Juan Zurita, Charles Creffield and Gloria Platero Quantum 7, 1043 (2023) Abstract The duration of bidirectional transfer protocols in 1D topological models usually scales exponentially with distance. In this work, we propose transfer protocols in multidomain SSH chains and Creutz ladders that lose the exponential dependence, greatly speeding up the…
Álvaro Gómez-León, Gloria Platero PRL 110, 200403 (2013) We propose a general framework to solve tight binding models in D dimensional lattices driven by ac electric fields. Our method is valid for arbitrary driving regimes and allows us to obtain effective Hamiltonians for different external field configurations. We establish an…
Miguel Bello, Charles E. Creffield and Gloria Platero Phys. Rev. B 95, 094303 (2017). We analyze the dynamics of two strongly interacting fermions moving in two-dimensional lattices under the action of a periodic electric field, both with and without a magnetic flux. Due to the interaction, these particles bind together…
G. Engelhardt, M. Benito, G. Platero and T. Brandes. Phys. Rev. Lett. 118, 197702 (2017). The relationship of topological insulators and superconductors and the field of nonlinear dynamics is widely unexplored. To address this subject, we adopt the linear coupling geometry of the Su-Schrieffer-Heeger model, a paradigmatic example for a…
Miguel Bello, Sigmund Kohler, and Gloria Platero Phys. Rev. B 96,045408 (2017) We study the dissipative decay of states with a doubly occupied site in a two-electron Hubbard model, known as doublons. For the environment, we consider charge and current noise, which are modeled as a bosonic heat bath that…
Guillem Rosselló, Rosa López, and Gloria Platero Phys. Rev. B 96,075305 (2017), We investigate the role of chirality on the performance of a Maxwell demon implemented in a quantum Hall bar with a localized impurity. Within a stochastic thermodynamics description, we investigate the ability of such a demon to drive…
Jordi Picó-Cortés, Fernando Domínguez, and Gloria Platero Phys. Rev. B 96, 125438 (2017) We investigate theoretical aspects of the detection of Majorana bound states in Josephson junctions using the semiclassical resistively capacitively shunted junction (RCSJ) model of junction dynamics. The influence of a 4π-periodic supercurrent contribution can be detected through…
Sigmund Kohler Phys. Rev. Lett. 119, 196802 (2017) We propose a protocol for the measurement of adiabatic phases of periodically driven quantum systems coupled to an open cavity that enables dispersive readout. It turns out that the cavity transmission exhibits peaks at frequencies determined by a resonance condition that involves…
M. Benito, A. Gómez-León, V. M. Bastidas, T. Brandes and G. Platero Pys. Rev. B 90, 205127 (2014) Floquet Majorana fermions appear as steady states at the boundary of time-periodic topological phases of matter. In this work, we theoretically study the main features of these exotic topological phases in the…
F. Forster, G. Petersen, S. Manus, P. Hänggi, D. Schuh, W. Wegscheider, S. Kohler, and S. Ludwig Phys. Rev. Lett 112, 116803 (2014) Controlling coherent interaction at avoided crossings and the dynamics there is at the heart of quantum information processing. A particularly intriguing dynamics is observed in the…
