Recently solvable SYK-like models of randomly interacting phonons and complex fermions in (0+1)-dimensions have been shown to match many of the properties of non-Fermi liquid superconductors. Superconductivity is better understood in higher dimensional models. We embed the phonon-fermion dot in a d-dimensional lattice and derive the effective action for collective fields. Near the saddle point, the model is governed by a phase field which is conjugated to charge fluctuations and impacts superconducting properties. At low energies the system is strongly coupled and is conjectured to have a gravitational dual. We discuss putative holographic theories able to match the IR behavior of the random phonon-fermion gas.<\/p>\n\n\n\n<div class=\"wp-block-file\"><a href=\"https:\/\/projects.ift.uam-csic.es\/holotube\/wp-content\/uploads\/2020\/10\/inkof.pdf\">inkof<\/a><a href=\"https:\/\/projects.ift.uam-csic.es\/holotube\/wp-content\/uploads\/2020\/10\/inkof.pdf\" class=\"wp-block-file__button\" download>Download<\/a><\/div>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\"  style=\"display: block; margin: 0px auto;\"  id=\"_ytid_43190\"  width=\"1170\" height=\"658\"  data-origwidth=\"1170\" data-origheight=\"658\" src=\"https:\/\/www.youtube.com\/embed\/QQwmvt2aQ88?enablejsapi=1&#038;autoplay=0&#038;cc_load_policy=0&#038;cc_lang_pref=&#038;iv_load_policy=1&#038;loop=0&#038;rel=1&#038;fs=1&#038;playsinline=0&#038;autohide=2&#038;theme=dark&#038;color=red&#038;controls=1&#038;\" class=\"__youtube_prefs__  epyt-is-override  no-lazyload\" title=\"YouTube player\"  allow=\"fullscreen; accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen data-no-lazy=\"1\" data-skipgform_ajax_framebjll=\"\"><\/iframe>\n<\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Gian Andrea Inkof Affiliation:Karlsruhe Institute of Technology Title:Superconductivity in SYK models Abstract:The tendency of non-Fermi liquid states towards superconductivity through pairing of fermionic excitations is complicated by the disappearance of quasi-particles at strong coupling.
