Shear Viscosity at the van Hove singularity
Yi-Hui Xing, Wu-Ming Liu
The applicability of the semiclassical Boltzmann transport theory is fundamentally challenged in strongly correlated systems where quasiparticle excitations are ill-defined. When t…
Strange metal at the Lifshitz transition
Yi-Hui Xing, Wu-Ming Liu, Xiao-Tian Zhang
Strange metal behavior is widely observed in cuprates, ruthenates, and twisted bilayer graphene. We study quantum critical transport at a two-dimensional Lifshitz transition, where…
Non-Fermi-Liquid/Marginal-Fermi-Liquid Signatures Induced by Van Hove Singularity
Yi-Hui Xing, Wu-Ming Liu
We theoretically study the two-dimensional metal that is coupled to critical magnons and features van Hove singularities on the Fermi surface. When there is only translationally in…
Interference of Two-Dimensional Bose-Einstein Condensates in Micro-Gravity
Tie-Fu Zhang, Hao Zhu, Wen-Kai Bai +3
We investigate the interference of two-dimensional Bose-Einstein condensates in micro-gravity, which influenced by the interaction strength, initial momentum, gravitational potenti…
