Besides others, it already finds important applications in atomic clocks, for medical purposes, and in the search for<span style=\"font-family: Ubuntu\">&nbsp;dark matter. Many currently employed quantum sensing protocols exhibit a simple setup, in which a laser probes the optical properties of an ensemble of atoms, molecules, or other quantum emitters, which are subject to the external stimulus to be measured. An important figure of merit to predict the sensitivity is the signal-to-noise ratio. While it is easy to&nbsp;<\/span><span style=\"font-family: Ubuntu\">theoretically calculate the signal, the accurate prediction of the noise is challenging.<\/span><\/p>\n<p>Motivated by this, we have developed the Photon-Resolved Floquet Theory (PRFT), which besides predicting the state of a driven quantum system (e.g., the atom or molecule), can also predict the number of photons exchanged with the coherent driving field [1,2]. To this end, the PRFT introduces counting fields into the semiclassical equations of motions, that track the photons in the driving field. Interestingly, the PRFT predicts light-matter entanglement in the Floquet-state basis. This effect can be employed to devise a measurement-based quantum communication protocol, which has favorable scaling properties over long distances. We apply the PRFT to spectroscopy, where it can predict the Fisher information of coherent spectroscopic signals [3]. The PRFT thus opens new paths to design and optimize quantum sensors based on AMO systems, which might assist in the discovery of new physics.<\/p>\n<p>[1] G. Engelhardt, S. Choudhury, and W. V.

However, the advent of the Noisy Intermediate-Scale Quantum (NISQ) era forces us to investigate dissipation and decoherence and to find ways to utilize them effectively. This talk aims to provide examples where interactions with the environment play a pivotal role in generating and detecting collective quantum phenomena, inspiring new perspectives on harnessing environment interactions for advancing quantum technologies. Firstly, we will delve into the emerging field of topological quantum synchronization, a novel form of synchronization where topology and dissipation intertwine to protect synchronized dynamics against perturbation. Next, we will explore how carefully tailored interactions with the environment induce energy migration within small quantum spin networks characterized by a superradiant speed-up, demonstrating the potential for utilizing dissipation as a resource rather than a hindrance. Finally, if time permits, I will introduce a novel methodology for probing quantum criticality in non-equilibrium systems. This method circumvents the shortcomings of standard perturbative expansions, enabling a comprehensive and thermodynamically consistent understanding of critical phenomena in systems coupled to non-Markovian reservoirs.<\/p>\n\t\t\t\t\t<\/div><!-- .entry-content -->\n\t\t\t\t<footer class=\"entry-meta\">\n\t\t\t<span class=\"entry-format\"><i class=\"crycon-aside\" title=\"Minientrada\"><\/i><\/span>\n\t\t\t\t\t<\/footer>\n\n\t<\/article><!-- #post-2095 -->\n\n\t<article id=\"post-2081\" class=\"post-2081 post type-post status-publish format-standard hentry category-sin-categoria\">\n\t\t<header class=\"entry-header\">\n\t\t\t\t<h2 class=\"entry-title\"><a href=\"https:\/\/wp.icmm.csic.es\/npqsic\/gloria-platero-elected-a-fellow-of-the-american-physical-society\/\" title=\"Enlace permanente a Gloria Platero elected a Fellow of the American Physical Society\" rel=\"bookmark\">Gloria Platero elected a Fellow of the American Physical Society<\/a><\/h2>\n\t\t\t\t<div class=\"entry-meta\">\n\t\t\t\t\t<\/div><!-- .entry-meta -->\n\t\t<\/header><!-- .entry-header -->\n\t\t\t\t<div class=\"entry-content\">\n\t\t\t<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-2084 aligncenter\" src=\"https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/11\/APS-fellow-png-300x237.png\" alt=\"\" width=\"591\" height=\"467\" srcset=\"https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/11\/APS-fellow-png-300x237.png 300w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/11\/APS-fellow-png-1024x809.png 1024w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/11\/APS-fellow-png-768x607.png 768w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/11\/APS-fellow-png-150x118.png 150w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/11\/APS-fellow-png.png 1309w\" sizes=\"auto, (max-width: 591px) 100vw, 591px\" \/><\/p>\n<p>Gloria Platero was elected a Fellow of the American Physical Society on 21st September, 2022, for key theoretical physics contributions to the development of novel quantum circuit functionalities and protocols required to implement quantum information applications in real systems.<\/p>\n\t\t\t\t\t<\/div><!-- .entry-content -->\n\t\t\t\t<footer class=\"entry-meta\">\n\t\t\t<span class=\"entry-format\"><i class=\"crycon-aside\" title=\"Minientrada\"><\/i><\/span>\n\t\t\t\t\t<\/footer>\n\n\t<\/article><!-- #post-2081 -->\n\n\t<article id=\"post-1975\" class=\"post-1975 post type-post status-publish format-standard hentry category-32 category-publications\">\n\t\t<header class=\"entry-header\">\n\t\t\t\t<h2 class=\"entry-title\"><a href=\"https:\/\/wp.icmm.csic.es\/npqsic\/fast-quantum-transfer-mediated-by-topological-domain-walls\/\" title=\"Enlace permanente a Fast quantum transfer mediated by topological domain walls\" rel=\"bookmark\">Fast quantum transfer mediated by topological domain walls<\/a><\/h2>\n\t\t\t\t<div class=\"entry-meta\">\n\t\t\t\t\t<\/div><!-- .entry-meta -->\n\t\t<\/header><!-- .entry-header -->\n\t\t\t\t<div class=\"entry-content\">\n\t\t\t<p>Juan Zurita, Charles Creffield and Gloria Platero<\/p>\n<p><a href=\"https:\/\/quantum-journal.org\/papers\/q-2023-06-22-1043\/\">Quantum 7, 1043 (2023)<\/a><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/quantum-journal.org\/wp-content\/uploads\/2023\/06\/Figure4.png\" width=\"768\" height=\"384\"><\/p>\n<p><strong>Abstract<\/strong><\/p>\n<p>The duration of bidirectional transfer protocols in 1D topological models usually scales exponentially with distance.

We also investigate how to harness the localization properties of the Creutz ladder-with two localized modes per domain wall-to choose the two states along the ladder that will be swapped during the transfer protocol, without disturbing the states located in the intermediate walls between them.

Along this direction, driving materials out of equilibrium with a time-periodic modulation has proven to be an efficient tool for realizing unconventional configurations as transient states, or even novel out-of-equilibrium phases. In these systems, known as Floquet materials, the electronic degrees of freedom are dressed by the interaction with the electric field, which can be exploited to engineer the electronic, dynamical and topological properties of materials. In solid-state platforms, such fields can be implemented by shining classical light, i.e., a high-intensity laser, on the sample.<\/p>\n<p style=\"text-align: left\">In recent years, the idea of using quantum light for the same task has gathered considerable attention. In these set-ups, the high-intensity laser can be replaced by individual photons trapped inside a quantum cavity that are made to interact coherently with a quantum material. Although there are crucial differences between both approaches, the strategies of driven systems can guide this new research route, and the resulting hybrid systems have been denominated cavity quantum materials.<\/p>\n<h5><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1961\" src=\"https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_2-300x93.png\" alt=\"\" width=\"632\" height=\"196\" srcset=\"https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_2-300x93.png 300w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_2-1024x316.png 1024w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_2-768x237.png 768w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_2-1536x475.png 1536w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_2-2048x633.png 2048w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_2-150x46.png 150w\" sizes=\"auto, (max-width: 632px) 100vw, 632px\" \/><\/h5>\n<p style=\"text-align: left\">&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1960 alignright\" style=\"text-indent: 10px\" src=\"https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_1-1024x946.png\" alt=\"\" width=\"391\" height=\"361\" srcset=\"https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_1-1024x946.png 1024w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_1-300x277.png 300w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_1-768x709.png 768w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_1-1536x1418.png 1536w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_1-2048x1891.png 2048w, https:\/\/wp.icmm.csic.es\/npqsic\/wp-content\/uploads\/sites\/51\/2023\/03\/figure_1-150x139.png 150w\" sizes=\"auto, (max-width: 391px) 100vw, 391px\" \/><\/p>\n<p style=\"text-align: left\">The present dissertation explores the interaction of both classical and quantum light with a particular class of quantum<span style=\"font-family: Ubuntu\">&nbsp;materials: topological insulators. The non-trivial topological properties of the bulk, which can be characterized by the value of a topological invariant, are related with the physics at the boundary, and lead to the appearance of topologically protected edge states. From a theoretical point of view, we investigate how the interaction with light can alter the topological features of a system, in two different aspects: first, by modifying the existing phase or by inducing non-trivial features in an otherwise trivial sample, and second, by hindering them. For this, different <\/span><span style=\"font-family: Ubuntu\">issues<\/span><span style=\"font-family: Ubuntu\"> have to be addressed: are there any broken symmetries in the interacting system? What is the fate of the edge states in a finite system? Are they topologically protected? Is the topological invariant well-defined? From these questions it becomes clear that complete characterization of topological phases requires studying both the boundary and the bulk physics.&nbsp;<\/span><\/p>\n\t\t\t\t\t<\/div><!-- .entry-content -->\n\t\t\t\t<footer class=\"entry-meta\">\n\t\t\t<span class=\"entry-format\"><i class=\"crycon-aside\" title=\"Minientrada\"><\/i><\/span>\n\t\t\t\t\t<\/footer>\n\n\t<\/article><!-- #post-1956 -->\n\n\t<article id=\"post-1937\" class=\"post-1937 post type-post status-publish format-standard has-post-thumbnail hentry category-29 category-articles tag-30\">\n\t\t<header class=\"entry-header\">\n\t\t\t\t<h2 class=\"entry-title\"><a href=\"https:\/\/wp.icmm.csic.es\/npqsic\/new-article-proposal-for-detection-of-the-0%e2%80%b2-and-%cf%80%e2%80%b2-phases-in-quantum-dot-josephson-junctions\/\" title=\"Enlace permanente a New Editors&#8217; Suggestion: Proposal for Detection of the 0\u2032 and \u03c0\u2032 Phases in Quantum-Dot Josephson Junctions\" rel=\"bookmark\">New Editors&#8217; Suggestion: Proposal for Detection of the 0\u2032 and \u03c0\u2032 Phases in Quantum-Dot Josephson Junctions<\/a><\/h2>\n\t\t\t\t<div class=\"entry-meta\">\n\t\t\t\t\t<\/div><!-- .entry-meta -->\n\t\t<\/header><!-- .entry-header -->\n\t\t\t\t<div class=\"entry-content\">\n\t\t\t<h5 class=\"authors\">We are pleased to announce our latest article and thank the APS for considering it an Editors&#8217; Suggestion on PRL.

A major effort in this direction has been devoted to using classical light in the form of Floquet drives to manipulate and induce states with non-trivial topology. A different route can be achieved with cavity photons. In this talk, I will discuss a prototypical model for topological phase transition, the one-dimensional Su-Schrieffer-Heeger (SSH) model, coupled to a single mode cavity [1]. I will demonstrate that quantum light can affect the topological properties of the system, including the finite-length energy spectrum hosting edge modes and the topological phase diagram. In particular, I will show that depending on the lattice geometry and the strength of light-matter coupling one can either turn a trivial phase into a topological one or vice versa using quantum cavity fields. Furthermore, the polariton spectrum of the coupled electron-photon system contains signatures of the topological phase transition in the SSH model.<\/p>\n<hr>\n<p><strong>References:<\/strong><\/p>\n<p>[1] Olesia Dmytruk and Marco Schir\u00f3, Controlling topological phases of matter with quantum light,&nbsp;<a href=\"https:\/\/arxiv.org\/abs\/2204.05922\">arXiv:2204.05922<\/a>.<\/p>\n\t\t\t\t\t<\/div><!-- .entry-content -->\n\t\t\t\t<footer class=\"entry-meta\">\n\t\t\t<span class=\"entry-format\"><i class=\"crycon-aside\" title=\"Minientrada\"><\/i><\/span>\n\t\t\t\t\t<\/footer>\n\n\t<\/article><!-- #post-1892 -->\n\n\t<article id=\"post-1795\" class=\"post-1795 post type-post status-publish format-standard has-post-thumbnail hentry category-other-activities\">\n\t\t<header class=\"entry-header\">\n\t\t\t\t<h2 class=\"entry-title\"><a href=\"https:\/\/wp.icmm.csic.es\/npqsic\/group-seminar-illuminating-van-der-waals-materials-from-graphene-to-twisted-mos2\/\" title=\"Enlace permanente a Group Seminar: Illuminating van der Waals materials: from graphene to twisted  MoS2\" rel=\"bookmark\">Group Seminar: Illuminating van der Waals materials: from graphene to twisted  MoS2<\/a><\/h2>\n\t\t\t\t<div class=\"entry-meta\">\n\t\t\t\t\t<\/div><!-- .entry-meta -->\n\t\t<\/header><!-- .entry-header -->\n\t\t\t\t<div class=\"entry-content\">\n\t\t\t<p style=\"text-align: left\"><strong>Marta Prada, <\/strong>from the Institute for Theoretical Physics, Universit\u00e4t Hamburg, will give a seminar entitled <strong><span style=\"color: #8eaebd\">\u00abIlluminating van der Waals materials: from graphene to twisted MoS2\u00bb.<\/span><\/strong><\/p>\n<p><strong>Date: October 11th, 2022, 11:00h.<\/strong><\/p>\n<p><strong>Location: <\/strong>Instituto de Ciencias Materiales de Madrid (ICMM-CSIC)<\/p>\n<p>We address the low-lying energy levels of van-der Waals structures via resistively-detected electron spin resonance (ESR). In graphene, the structure of the topological bands is reflected in transport experiments, where our numerical models allow us to identify the resonance signatures. We resolve the intrinsic spin-orbit gap [1], the g-factor anisotropic corrections [2, 3], the sub-lattice splitting [4], and the hyperfine-induced splitting in 13C-based graphene [5]. Using Floquet formalism, we find theoretical evidence of a topological transition by illuminating an ideal sample of graphene and the connection between angular momentum and sublattice spin. Finally, we study twisted MoS2 samples, where we resolve low-lying Moir\u00e9 bands near the conduction band.<\/p>\n<p style=\"text-align: left\">Keywords: Twisted bilayer MoS2, Moir\u00e9, superlattices, Mini-bands, Schottky barrier, Resonant Tunneling,<br \/>\nTransition metal dichalcogenides<\/p>\n<p>[1] J.
