Breakdown of the Migdal approximation at Lifshitz

Apr 20,2016·While 203 K high temperature superconductivity in H 3 S has been interpreted by BCS theory in the dirty limit here we focus on the effects of hydrogen zero-point-motion and the multiband electronic structure relevant for multigap superconductivity near Lifshitz transitions.We describe how the topology of the Fermi surfaces evolves with pressure giving different Lifshitz-transitions.Cited by 10Publish Year 2018Author Katsuya Shimizu,Mari Einaga,Masafumi Sakata,Akiyoshi Masuda,Harushige Nakao,Mikhail Eremets,AlEmergence of superconductivity in doped H 2 O ice at high Jul 28,2017·Introduction.The theoretical prediction 1 and subsequent experimental discovery 2 of superconductivity in H 3 S at 200 GPa,with the record critical temperature (T C) of 203 K,rekindled the century-old dream of a room temperature superconductor.The mechanism for superconductivity is clearly understood within the strong coupling theory of Bardeen,Cooper,and Schrieffer 3 and the highCited by 26Publish Year 2019Author Xiaoli Huang,Xin Wang,Defang Duan,Bertil Sundqvist,Bertil Sundqvist,Xin Li,Yanping Huang,HongStructure and superconductivity of hydrides at high To note,superconductivity under pressure has been extended to most elements of periodic table.Back in the year 1935,Wigner and Huntington theoretically predicted that solid hydrogen would be metallized at high pressure,that is metallic hydrogen ,which is believed to be a room-temperature superconductor .Therefore,searching for metallic
