Solving Nonequilibrium Dynamics via Influence Matrix Bootstrap: Floquet-PXP Model
Xiao-Yang Yang, He-Ran Wang, Zhong Wang
Studies of integrable systems have profoundly deepened the fundamental understanding of quantum many-body physics. While equilibrium properties such as ground states and thermodyna…
Non-Bloch self-energy of dissipative interacting fermions
He-Ran Wang, Zijian Wang, Zhong Wang
The non-Hermitian skin effect describes the phenomenon of exponential localization of single-particle eigenstates near the boundary of the system. We consider its generalization to…
Exact Hidden Markovian Dynamics in Quantum Circuits
He-Ran Wang, Xiao-Yang Yang, Zhong Wang
Characterizing nonequilibrium dynamics in quantum many-body systems is a challenging frontier of physics. In this Letter, we systematically construct solvable nonintegrable quantum…
Steady-state topological order
Xu-Dong Dai, Zijian Wang, He-Ran Wang +1
We investigate a generalization of topological order from closed systems to open systems, for which the steady states take the place of ground states. We construct typical lattice…
