This talk explores the interplay between altermagnetism and superconductivity, focusing on how impurities can serve as local probes of altermagnetic superconductors. I will briefly introduce altermagnetic materials, their interplay with superconductivity, and review the basic theory of impurity states in superconductors. I will then present our original theoretical work on the role of impurities in altermagnetic superconductors, predicting the emergence of spin-polarized subgap states that extend along the crystal axes. These states form degenerate doublets, which can be split by crystal symmetry breaking or a magnetic field aligned with the N\u00e9el vector. Their unique spatial and spin properties provide measurable signatures via scanning tunneling microscopy, serving as a hallmark for altermagnetic superconductivity. Finally, I will discuss the interaction between impurities, revealing a position-dependent, spin-selective coupling that enables in-situ control of devices crucial for quantum information processing and topological superconductivity.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Andrea Maiani WINQ Postdoctoral fellow, Nordita. &nbsp; Impurity States in Altermagnetic Superconductors When: 12:00-13:00 CET, November 26th (Tuesday), 2024 Where: Sala de Seminarios (182), ICMM-CSIC, Campus de Cantoblanco, Madrid &nbsp; Altermagnets are a novel class of magnetic materials distinct from ferromagnets and antiferromagnets, characterized by vanishing net magnetization and unique spin-split band structures \u2013 appealing &hellip; <a href=\"https:\/\/wp.icmm.csic.es\/seminars\/2024\/11\/18\/andrea-maiani-26-11-24\/\" class=\"more-link\">Continue reading <span class=\"screen-reader-text\">Andrea Maiani (26\/11\/24)<\/span> <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":103,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-406","post","type-post","status-publish","format-standard","hentry","category-sin-categoria"],"_links":{"self":[{"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/posts\/406","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/users\/103"}],"replies":[{"embeddable":true,"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/comments?post=406"}],"version-history":[{"count":1,"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/posts\/406\/revisions"}],"predecessor-version":[{"id":408,"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/posts\/406\/revisions\/408"}],"wp:attachment":[{"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/media?parent=406"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/categories?post=406"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wp.icmm.csic.es\/seminars\/wp-json\/wp\/v2\/tags?post=406"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
