We identify three Goldstone branches, each with first-sound, second-sound or spin-sound character. In analogy with a diatomic crystal, the resulting lattice has a two-domain primitive basis, and we find that the crystal (first-sound-like) branch is split into optical and acoustic phonons. We also find a spin-Higgs branch that is associated with the supersolid modulation amplitude.<\/p>\r\n<p><br \/>See the paper here: <a href=\"https:\/\/journals.aps.org\/prl\/abstract\/10.1103\/PhysRevLett.133.103401\">PhysRevLett.133.103401<\/a> and <a href=\"https:\/\/arxiv.org\/abs\/2312.03390\">arXiv:2312.03390<\/a><\/p>\r\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Together with our local ultracold theory collaborator Russell Bisset and external collaborator Blair Blakie and their teams, we investigate the excitation spectrum of binary supersolids, revealing new sound and Higgs modes that are unique to this system!<\/p>\n","protected":false},"author":26,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[42],"tags":[],"_links":{"self":[{"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/posts\/51685"}],"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\/26"}],"replies":[{"embeddable":true,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/comments?post=51685"}],"version-history":[{"count":4,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/posts\/51685\/revisions"}],"predecessor-version":[{"id":52840,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/posts\/51685\/revisions\/52840"}],"wp:attachment":[{"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/media?parent=51685"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/categories?post=51685"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.erbium.at\/FF\/wp-json\/wp\/v2\/tags?post=51685"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
