Two-mode collapse and revival of quantum coherent state in a tilted optical lattice
Chi-Kin Lai, Shengjie Jin, Yuanzhe Hu +6
Collective dynamics is an important out-of-equilibrium feature of quantum coherent states and usually reflects the intrinsic properties of the state. Collapse and revival (CR) dyna…
Observation of a tripartite quantum phase for coexisting extended, localized, and critical states
Zhongshu Hu, Yajing Guo, Yu-Dong Wei +8
The disordered quantum world hosts three fundamental types of states: extended, localized, and critical, of which the critical states are confined to fine-tuned critical points or…
Experimental engineering of Floquet topological phases in a one-dimensional optical lattice
Pengju Zhao, Yudong Wei, Zhongshu Hu +3
Periodic driving enables realization of topological phases without static counterparts. We experimentally realize and detect a one-dimensional anomalous Floquet topological phase i…
A Radio-Frequency Emitter Design for the Low-Frequency Regime in Atomic Experiments
Yudong Wei, Zhongshu Hu, Yajing Guo +4
Radio-frequency (RF) control is a key technique in cold atom experiments. We present a compact and efficient RF circuit based on a capacitive transformer network, where a low-frequ…
