We uncover a wide range of exotic phases, including superconducting, topological, and\u2014most strikingly\u2014<em>topological superconducting<\/em> states. The latter presents several aspects of novelty. The most intriguing one is that differently from the paradigmatic example of one-dimensional topological superconductivity appearing in the celebrated Kitaev chain, this phase is purely induced by competing interactions. We also outline how these phases can be realized and detected with current experimental tools, opening a powerful new route for a deeper understanding of strongly interacting fermionic quantum matter.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We uncover a wide range of exotic phases in the iconic t-J model, including superconducting, topological, and\u2014most strikingly\u2014topological superconducting states.<\/p>\n","protected":false},"author":34,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[38,42],"tags":[],"_links":{"self":[{"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/posts\/54382"}],"collection":[{"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/users\/34"}],"replies":[{"embeddable":true,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/comments?post=54382"}],"version-history":[{"count":2,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/posts\/54382\/revisions"}],"predecessor-version":[{"id":54386,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/posts\/54382\/revisions\/54386"}],"wp:attachment":[{"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/media?parent=54382"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/categories?post=54382"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/tags?post=54382"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
