Mass hierarchy in collective modes of pair-density-wave superconductors
Shao-Kai Jian, Michael M. Scherer, Hong Yao
We study collective modes near the quantum critical point of a pair-density-wave (PDW) superconductor in 2+1 dimensions. The fate of gaps of various collective modes is investigate…
Violation of the viscosity/entropy bound in translationally invariant non-Fermi liquids
Xian-Hui Ge, Shao-Kai Jian, Yi-Li Wang +2
The shear viscosity is an important characterization of how a many-body system behaves like a fluid. We study the shear viscosity in a strongly interacting solvable model, consisti…
Quantum criticality preempted by nematicity
Shi-Xin Zhang, Shao-Kai Jian, Hong Yao
Exotic physics often emerges around quantum criticality in metallic systems. Here we explore the nature of topological phase transitions between 3D double-Weyl semimetals and insul…
Exciton Condensation in Quantum Hall Bilayers at Total Filling
Zheng Zhu, Shao-Kai Jian, D. N. Sheng
We study the coupled quantum Hall bilayers each at half-filled first excited Landau levels with varying the layer distance. Based on numerical exact diagonalization on torus, we id…
Universal properties of many-body quantum chaos at Gross-Neveu criticality
Shao-Kai Jian, Hong Yao
Quantum chaos in many-body systems may be characterized by the Lyapunov exponent defined as the exponential growth rate of out-of-time-order correlators (OTOC). So far Lyaponov exp…
Global phase diagram of the one-dimensional Sachdev-Ye-Kitaev model at finite
Xin Dai, Shao-Kai Jian, Hong Yao
Many key features of the higher-dimensional Sachdev-Ye-Kitaev (SYK) model at {\it finite} remain unknown. Here we study the SYK chain consisting of () fermions p…
