A Chern-Simons theory for dipole symmetry
Xiaoyang Huang
We present effective field theories for dipole symmetric topological matters that can be described by the Chern-Simons theory. Unlike most studies using higher-rank gauge theory, w…
Deep reinforcement learning for quantum Hamiltonian engineering
Pai Peng, Xiaoyang Huang, Chao Yin +3
Engineering desired Hamiltonian in quantum many-body systems is essential for applications such as quantum simulation, computation and sensing. Conventional quantum Hamiltonian eng…
Prethermal quasiconserved observables in Floquet quantum systems
Chao Yin, Pai Peng, Xiaoyang Huang +2
Prethermalization, by introducing emergent quasiconserved observables, plays a crucial role in protecting Floquet many-body phases over exponentially long time, while the ultimate…
Observation of Floquet prethermalization in dipolar spin chains
Pai Peng, Chao Yin, Xiaoyang Huang +2
Periodically driven Floquet quantum systems provide a promising platform to investigate novel physics out of equilibrium. Unfortunately, the drive generically heats up the system t…
Bell inequalities violation within non-Bunch-Davies states
Jun Feng, Xiaoyang Huang, Yao-Zhong Zhang +1
We study the quantum nature of non-Bunch-Davies states in de Sitter space by evaluating CHSH inequality on a localized two-atom system. We show that quantum nonlocality can be gene…
Quantum estimation in an expanding spacetime
Xiaoyang Huang, Jun Feng, Yao-Zhong Zhang +1
We investigate the quantum estimation on the Hubble parameter of an expanding de Sitter space by quantum metrological techniques. By exploring the dynamics of a freely falling Unru…
