State-selective entanglement and point-gap topology in the unidirectional Bose-Hubbard chain

Chuan-Fu Lin, Yu-Chin Tzeng, Po-Yao Chang

We study the effect of repulsive interactions on skin modes and entanglement in the unidirectional Bose--Hubbard model. Although the ground state of this integrable model undergoes…

Hyperbolic polaritons in topological nodal ring semimetals

Ashutosh Singh, Maria Sebastian, Yuanping Chen +2

In mirror-symmetric systems, there is a possibility of the realization of extended gapless electronic states characterized as nodal lines or rings. Strain induced modifications to…

Prethermalization and transient dynamics of the Multi-Channel Kondo systems under generic quantum quenches: Insights form Large- Schwinger-Keldysh approach

Iksu Jang, Po-Yao Chang

Understanding out-of-equilibrium many-body quantum systems is crucial in contemporary physics. However, capturing the universal dynamics of such systems remains challenging despite…

Interaction-induced Metal to Topological Insulator Transition

Yu-Chin Tzeng, Po-Yao Chang, Min-Fong Yang

By means of exact diagonalizations, the Bernevig-Hughes-Zhang model at quarter-filling in the limit of strong Hubbard on-site repulsion is investigated. We find that the non-intera…

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…
