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…

Geometry and superfluidity of the flat band in a non-Hermitian optical lattice
Peng He, Hai-Tao Ding, Shi-Liang Zhu
We propose an ultracold-atom setting where a fermionic superfluidity with attractive s-wave interaction is uploaded in a non-Hermitian Lieb optical lattice. The existence of a real…

Tensor monopoles and negative magnetoresistance effect in optical lattices
Hai-Tao Ding, Yan-Qing Zhu, Zhi Li +1
We propose that a kind of four-dimensional (4D) Hamiltonians, which host tensor monopoles related to quantum metric tensor in even dimensions, can be simulated by ultracold atoms i…
