Coplanar order induced by emergent frustration
Zehui Deng, Lu Liu, Wenan Guo +1
Traditional frustration arises from the conflict between the spin alignments due to the geometry or the nature of the interactions. Here, we demonstrate a novel form of frustration…

Universal Behavior in Entanglement Entropy Reveals Quantum Criticality and Underlying Symmetry Breaking
Zhe Wang, Zehui Deng, Zenan Liu +5
Entanglement plays a key role in quantum physics, but how much information it can extract from many-body systems is still an open question, particularly regarding quantum criticali…

Diagnosing Symmetry and First-Order Transition in the Model via Entanglement Entropy
Zehui Deng, Lu Liu, Wenan Guo +1
We study the scaling behavior of the Rényi entanglement entropy with smooth boundaries at the phase transition point of the two-dimensional model. Using the recently develo…
