Evolution of entanglement spectra under generic quantum dynamics
Po-Yao Chang, Xiao Chen, Sarang Gopalakrishnan +1
We characterize the early stages of the approach to equilibrium in isolated quantum systems through the evolution of the entanglement spectrum. We find that the entanglement spectr…
Quantum chaos dynamics in long-range power law interaction systems
Xiao Chen, Tianci Zhou
We use out-of-time-order commutator (OTOC) to diagnose the propagation of chaos in one dimensional long-range power law interaction system. We map the evolution of OTOC to a classi…
Multiple topological transitions in twisted bilayer graphene near the first magic angle
Kasra Hejazi, Chunxiao Liu, Hassan Shapourian +2
Recent experiments have observed strongly correlated physics in twisted bilayer graphene (TBG) at very small angles, along with nearly flat electron bands at certain fillings. A go…
Operator Dynamics in Brownian Quantum Circuit
Tianci Zhou, Xiao Chen
We explore the operator dynamics in a random -spin model with pairwise interactions (Brownian quanum circuit). We introduce the height of an operator to characterize its spa…
Operator scrambling and quantum chaos
Xiao Chen, Tianci Zhou
Operator scrambling is a crucial ingredient of quantum chaos. Specifically, in the quantum chaotic system, a simple operator can become increasingly complicated under unitary time…
A candidate Theory for the "Strange Metal" phase at Finite Energy Window
Xiaochuan Wu, Xiao Chen, Chao-Ming Jian +2
We propose a lattice model for strongly interacting electrons with the potential to explain the main phenomenology of the strange metal phase in the cuprate high temperature superc…
Entanglement signatures of emergent Dirac fermions: kagome spin liquid & quantum criticality
Wei Zhu, Xiao Chen, Yin-Chen He +1
Quantum spin liquids (QSL) are exotic phases of matter that host fractionalized excitations. It is difficult for local probes to characterize QSL, whereas quantum entanglement can…
