This system has topological semimetal-like crossing nodes in the spectrum of hydrodynamic modes that require the protection of a special combination of translational and boost symmetries in two spatial directions. One possible origin for the non-conservation terms of the energy momentum tensor is an external gravitational field which could be generated by a specific coordinate transformation from the flat spacetime. This suggests that topologically trivial modes could become topologically nontrivial by being observed in a special non-inertial reference frame. Finally a holographic realization of this system will be introduced.\u00a0<\/p>\n\n\n\n<div class=\"wp-block-file\"><a href=\"https:\/\/projects.ift.uam-csic.es\/holotube\/wp-content\/uploads\/2020\/11\/topohydroHolotube.pptx\">topohydroHolotube<\/a><a href=\"https:\/\/projects.ift.uam-csic.es\/holotube\/wp-content\/uploads\/2020\/11\/topohydroHolotube.pptx\" class=\"wp-block-file__button\" download>Download<\/a><\/div>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/upload.wikimedia.org\/wikipedia\/commons\/e\/e4\/Borromean_Seifert_surface.png\" alt=\"File:Borromean Seifert surface.png - Wikipedia\" width=\"364\" height=\"458\"\/><\/figure><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Date : 24th of November 2020, 15:00 CET Ya-Wen Sun&nbsp;(UCAS Beijing) Link:&nbsp;https:\/\/zoom.us\/j\/96945024145?pwd=aHM4emtlWFJ0M2VBd1pCSmhtYVptdz09 Title:&nbsp;Topological modes in hydrodynamics and holography Abstract:\u00a0In this talk I will show that gapless modes in relativistic hydrodynamics could become topologically nontrivial by weakly breaking the conservation of energy momentum tensor in a specific way.
