Quantum geometric bounds at finite temperature for one-dimensional chiral systems
Peng He, Hai-Tao Ding, Yu-Guo Liu
The geometry and topology of quantum states are intimately related at zero temperature through exact bounds that constrain geometric quantities from below by topological invariants…

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…

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…
