I will describe how these methods might be used to experimentally reveal quantum critical dynamics which is invisible in conventional bulk transport measurements. Using the AdS4-Einstein-Maxwell system as a toy model, I will describe what happens as current is pushed through a geometric constriction in both hydrodynamic and quantum critical transport regimes, both in charge neutral and non-zero density limits. Remarkably, our model does appear to quantitatively capture locally imaged transport in charge neutral graphene at high temperatures, albeit in a largely ohmic transport regime.<\/p>\n<\/div><\/div>\n\n\n<iframe loading=\"lazy\"  style=\"display: block; margin: 0px auto;\"  id=\"_ytid_75724\"  width=\"1170\" height=\"658\"  data-origwidth=\"1170\" data-origheight=\"658\" src=\"https:\/\/www.youtube.com\/embed\/UUPYYEB942E?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__  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\n\n<div class=\"wp-block-file\"><a href=\"https:\/\/projects.ift.uam-csic.es\/holotube\/wp-content\/uploads\/2021\/06\/holotube2021.pdf\">Slides<\/a><a href=\"https:\/\/projects.ift.uam-csic.es\/holotube\/wp-content\/uploads\/2021\/06\/holotube2021.pdf\" class=\"wp-block-file__button\" download>Download<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Date : June 8, 2021, 18:00 CEST Andrew Lucas (University of Colorado Boulder) Link:&nbsp;https:\/\/zoom.us\/j\/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Title:&nbsp;Fingerprints of quantum criticality in locally resolved transport Abstract:&nbsp; New experimental methods such as nitrogen vacancy center magnetometry allow for the imaging of local transport phenomena well below the micrometer scale.
