Entanglement Growth from Entangled States: A Unified Perspective on Entanglement Generation and Transport
Chun-Yue Zhang, Zi-Xiang Li, Shi-Xin Zhang
Studies of entanglement dynamics in quantum many-body systems have focused largely on initial product states. Here, we investigate the far richer dynamics from initial entangled st…
Universal Decay of Mutual Information and Conditional Mutual Information in Gapped Pure- and Mixed-State Quantum Matter
Jinmin Yi, Kangle Li, Chuan Liu +2
For spin and fermionic systems in any spatial dimension, we establish that the superpolynomial decay behavior of mutual information and conditional mutual information is a universa…
Bond Additivity and Persistent Geometric Imprints of Entanglement in Quantum Thermalization
Chun-Yue Zhang, Shi-Xin Zhang, Zi-Xiang Li
Characterizing the intricate structure of entanglement in quantum many-body systems remains a central challenge, as standard measures often obscure underlying geometric details. In…
Graph-theoretical search for integrable multistate Landau-Zener models
Zixuan Li, Chen Sun
The search for exactly solvable models is an evergreen topic in theoretical physics. In the context of multistate Landau-Zener models -- -state quantum systems with linearly tim…
