Critical Entanglement Dynamics at Dynamical Quantum Phase Transitions
Kaiyuan Cao, Mingzhi Li, Xiang-Ping Jiang +2
We investigate the critical behavior of momentum-space entanglement entropy at dynamical quantum phase transitions (DQPTs) in translationally invariant two-band insulators and supe…
Phase-Singularity Control of Topological Acoustic Spin Textures
Huaijin Ma, Te Liu, Jiachen Sheng +6
Acoustic spin textures provide a degree of freedom for programmable topological field states, yet a unified framework for constructing and classifying higher-order textures in open…
Maximal Entanglement and Frozen Information: A Unified Framework for Dynamical Quantum Phase Transitions
Kaiyuan Cao, Mingzhi Li, Xiang-Ping Jiang +2
Dynamical quantum phase transitions (DQPTs) are temporal singularities marked by zeros of the Loschmidt echo, yet their underlying quantum-information structure remains elusive. He…
Tailoring Dynamical Quantum Phase Transitions via Double-Mode Squeezing Manipulation
Kaiyuan Cao, Haodong Wang, Xiang-Ping Jiang +2
We propose a protocol to tailor dynamical quantum phase transitions (DQPTs) by double-mode squeezing onto the initial state in the XY chain. The effect of squeezing depends critica…
