Emergent Symmetry and Phase Transitions on the Domain Wall of Topological Orders
Hong-Hao Song, Chen Peng, Rui-Zhen Huang +1
The one-dimensional (1D) domain wall of 2D topological orders is studied theoretically. The Ising domain wall model is shown to have an emergent SU(2) confor…
Squeezing and Entanglement Dynamics in Phase-Sensitive Non-Hermitian Systems
Ruicong Huang, Wencong Wang, Yuyang Liang +2
Over the past decade, parity-time (PT) symmetry and anti-PT (APT) symmetry in various physical systems have been extensively studied, leading to significant experimental and theore…
Noninvertible Symmetry-Enriched Quantum Critical Point
Linhao Li, Rui-Zhen Huang, Weiguang Cao
Noninvertible symmetry generalizes traditional group symmetries, advancing our understanding of quantum matter, especially one-dimensional gapped quantum systems. In critical latti…
Universal entanglement correction induced by relevant deformations at the quantum critical point
Rui-Zhen Huang, Chen Peng
Local relevant deformations are important tool to study universal properties of quantum critical points. We investigate the effect of small relevant deformations on the bi-partite…
