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 metals are ubiquitously observed in a variety of strongly correlated materials, among which high temperature cuprates\cite{Greene2020} and twisted bilayer graphenes\cite{Ca…

Spin pumping effect in non-Fermi liquid metals
Xiao-Tian Zhang, Yi-Hui Xing, Xu-Ping Yao +3
Spin pumping effect is a sensitive and well-established experimental method in two-dimensional (2D) magnetic materials. We propose that spin pumping effect can be a valuable probe…
