Identifying non-Hermitian critical points with quantum metric
Jun-Feng Ren, Jing Li, Hai-Tao Ding +1
The geometric properties of quantum states is fully encoded by the quantum geometric tensor. The real and imaginary parts of the quantum geometric tensor are the quantum metric and…
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…
Direct Probe of Topology and Geometry of Quantum States on IBM Q
Tianqi Chen, Hai-Tao Ding, Ruizhe Shen +2
The concepts of topology and geometry are of critical importance in exploring exotic phases of quantum matter. Though they have been investigated on various experimental platforms,…
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…
