Floquet quantum geometry in periodically driven topological insulators
Peng He, Jian-Te Wang, Jiangbin Gong +1
Quantum geometry plays a fundamental role across many branches of modern physics, yet its full characterization in nonequilibrium systems remains a challenge. Here, we propose a fr…
Proposal for realizing and probing topological crystalline insulators in optical lattices
Jing-Xin Liu, Jian-Te Wang, Shi-Liang Zhu
We develop a lattice model which exhibits topological transitions from topological insulators to mirror symmetry-protected topological crystalline insulators by introducing a…
Detecting degenerate bands topological invariants in optical lattice
Jing-Xin Liu, Jian-Te Wang, Hai-Tao Ding
In this paper, we present a novel experimental approach for simulating and detecting topological invariants using ultracold fermions confined in two-dimensional hexagonal optical l…
Realizing and detecting Stiefel-Whitney insulators in an optical Raman lattice
Jian-Te Wang, Jing-Xin Liu, Hai-Tao Ding +1
We propose a feasible scheme to realize a four-band Stiefel-Whitney insultor (SWI) with spin-orbit coupled ultracold atoms in an optical Raman lattice. Four selected spin states ar…
Non-Abelian quantum geometric tensor in degenerate topological semimetals
Hai-Tao Ding, Chang-Xiao Zhang, Jing-Xin Liu +3
The quantum geometric tensor (QGT) characterizes the complete geometric properties of quantum states, with the symmetric part being the quantum metric, and the antisymmetric part b…
Quantum quenches in a pseudo-Hermitian Chern insulator
Peng He, Yan-Qing Zhu, Jian-Te Wang +1
We propose to uncover the topology of a pseudo-Hermitian Chern insulator by quantum quench dynamics. The Bloch Hamiltonian of the pseudo-Hermitian Chern insulator is defined in the…
Extracting non-Abelian quantum metric tensor and its related Chern numbers
Hai-Tao Ding, Yan-Qing Zhu, Peng He +4
The complete geometry of quantum states in parameter space is characterized by the quantum geometric tensor, which contains the quantum metric and Berry curvature as the real and i…
Damping transition in an open generalized Aubry-André-Harper model
Peng He, Yu-Guo Liu, Jian-Te Wang +1
We study the damping dynamics of the single-particle correlation for an open system under periodic and aperiodic order, which is dominated by the Lindblad master equation. In the a…
