Tori, Klein Bottles, and Modulo 8 Parity/Time-reversal Anomalies of 2+1d Staggered Fermions
Nathan Seiberg, Wucheng Zhang
We study the symmetries of lattice staggered fermions in 2+1d. Using the symmetries, we can place the system on any sheared torus or Klein bottle. These different backgrounds provi…
Non-Equilibrium Phase Transition in a Boundary-Driven Dissipative Fermionic Chain
Hao Chen, Wucheng Zhang, Manas Kulkarni +1
We demonstrate that a boundary-localized periodic (Floquet) drive can induce nontrivial long-range correlations in a non-interacting fermionic chain which is additionally subject t…
LSM and CPT
Nathan Seiberg, Shu-Heng Shao, Wucheng Zhang
We study a number of 1+1d lattice models with anti-unitary symmetries that simultaneously reflect space and reverse time. Some of these symmetries are anomalous, leading to Lieb-Sc…
Sequential Generation of Two-dimensional Super-area-law States with Local Parent Hamiltonian
Wucheng Zhang
We construct examples of highly entangled two-dimensional states by exploiting a correspondence between stochastic processes in dimensions and quantum states in dimension…
Periodically Driven Open Quantum Systems: Spectral Properties and Non-Equilibrium Steady States
Hao Chen, Yu-Min Hu, Wucheng Zhang +5
In this article, we investigate periodically driven open quantum systems within the framework of Floquet-Lindblad master equations. Specifically, we discuss Lindblad master equatio…
