Electric circuit analog of Landau-Zener tunneling using time-varying elements
Enhong Cheng, Zheng Lian, Zezhou Chen +1
Landau-Zener tunneling (LZT) is a fundamental dynamical phenomenon, ubiquitous in various quantum systems. Here, we propose a time-varying electric circuit to address the question…
Direct measurement of the quantum geometric tensor in pseudo-Hermitian systems
Ze-Hao Huang, Hai-Tao Ding, Li-Jun Lang
The quantum geometric tensor (QGT) fundamentally encodes the geometry and topology of quantum states in both Hermitian and non-Hermitian regimes. While adiabatic perturbation theor…
Interaction-induced reentrance of Bose glass and quench dynamics of Bose gases in twisted bilayer and quasicrystal optical lattices
Shi-Hao Ding, Li-Jun Lang, Qizhong Zhu +1
We investigate the ground-state and dynamical properties of ultracold Bose gases in optical lattices with a quasicrystal structure, inspired by recent experiments on twisted bilaye…
Non-Abelian geometry, topology, and dynamics of a nonreciprocal Su-Schrieffer-Heeger ladder
Ziyu Zhou, Zhi-Cong Xu, Li-Jun Lang
Non-Hermiticity naturally breaks down the adiabaticity and thus leads to non-Abelian behaviors in multi-band systems. Here, we study how non-Abelian properties emerge in non-Hermit…
