Mode softening in time-crystalline transitions of open quantum systems
Xiaotian Nie, Wei Zheng
In this work, we generalize the concept of roton softening mechanism of spatial crystalline transition to time crystals in open quantum systems. We study a dissipative Dicke model…
Probing quantum many-body correlations by universal ramping dynamics
Libo Liang, Wei Zheng, Ruixiao Yao +11
Ramping a physical parameter is one of the most common experimental protocols in studying a quantum system, and ramping dynamics has been widely used in preparing a quantum state a…
Controlling higher-orbital quantum phases of ultracold atoms via coupling to optical cavities
Hui Tan, Jinsen Han, Wei Zheng +2
Orbital degree of freedom plays an important role in understanding exotic phenomena of strongly correlated materials. We study strongly correlated ultracold bosonic gases coupled t…
Topological Higgs Amplitude Modes in Strongly Interacting Superfluids
Junsen Wang, Youjin Deng, Wei Zheng
By studying the 2-dimensional Su-Schrieffer-Heeger-Bose-Hubbard model, we show the existence of topological Higgs amplitude modes in the strongly interacting superfluid phase. Usin…
Topological Micromotion of Floquet Quantum Systems
Peng Xu, Wei Zheng, Hui Zhai
The Floquet Hamiltonian has often been used to describe a time-periodic system. Nevertheless, because the Floquet Hamiltonian depends on a micro-motion parameter, the Floquet Hamil…
Nonlinear Hall response in the driving dynamics of ultracold atoms in optical lattices
Xiao-Long Chen, Wei Zheng
We propose that a nonlinear Hall response can be observed in Bloch oscillations of ultracold atoms in optical lattices under the condition of preserved time-reversal symmetry. In t…
