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…
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…
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…
