Relating non-Hermitian and Hermitian quantum systems at criticality
Chang-Tse Hsieh, Po-Yao Chang
We demonstrate three types of transformations that establish connections between Hermitian and non-Hermitian quantum systems at criticality, which can be described by conformal fie…

2D Gapless Topological Superfluids Generated by Pairing Phases
Jiapei Zhuang, Ching-Yu Huang, Po-Yao Chang +1
We systematically investigate the ground state phase diagram and the finite temperature phase transitions for a Rydberg-dressed Fermi gas loaded in a bilayer optical lattice. When…

General properties of fidelity in non-Hermitian quantum systems with PT symmetry
Yi-Ting Tu, Iksu Jang, Po-Yao Chang +1
The fidelity susceptibility is a tool for studying quantum phase transitions in the Hermitian condensed matter systems. Recently, it has been generalized with the biorthogonal basi…
