Dynamical singularity of the rate function for quench dynamics in finite-size quantum systems
Yumeng Zeng, Bozhen Zhou, Shu Chen
The dynamical quantum phase transition is characterized by the emergence of nonanalytic behaviors in the rate function, corresponding to the occurrence of exact zero points of the…

Holographic Anomalous Chiral Current Near a Boundary
Rong-Xin Miao, Yu-Qian Zeng
Due to the Weyl anomaly, an axial vector field produces novel anomalous chiral currents in spacetime with boundaries. Remarkably, the chiral current is not invariant under the gaug…

Bounded light cone and robust topological order out of equilibrium
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +3
The ground state degeneracy of topologically ordered gapped Hamiltonians is the bedrock for self-correcting quantum memories, which are unfortunately not stable away from equilibri…
