Lee-Yang Zeros and Pseudocritical Drift in J-Q Néel-VBS Transitions
Chunhao Guo, Zhe Wang, Danhe Wang +3
Square-lattice J-Q models provide a sign-problem-free setting for probing the quantum phase transition between Néel antiferromagnet and columnar valence-bond solid. We analyze this…
Entanglement Rényi Negativity across the Finite-Temperature Transition in the O(3) Universality Class
Dong-Xu Liu, Yi-Ming Ding, Zhe Wang +1
The fate of quantum entanglement at finite-temperature phase transitions remains an open question, particularly for continuous symmetry breaking where zero-temperature Goldstone mo…
Generalized Reduced-Density-Matrix Quantum Monte Carlo Gives Access to More
Zhiyan Wang, Zhe Wang, Bin-Bin Mao +1
For a long time, people have been focusing on how to extract more information, such as off-diagonal observables, from the quantum Monte Carlo (QMC) simulation of the partition func…
Universal and non-universal contributions of entanglement under different bipartitions
Zhe Wang, Chunhao Guo, Bin-Bin Mao +1
Entanglement entropy (EE) is a fundamental probe of quantum phases and critical phenomena, which was thought to reflect only bulk universality for a long time. Very recently, peopl…
Bipartite entanglement and surface criticality: The extra contribution of non-ordinary edge in entanglement
Yanzhang Zhu, Zenan Liu, Zhe Wang +2
Recent works on the scaling behaviors of entanglement entropy at the SO(5) deconfined quantum critical point (DQCP) sparked a huge controversy. Different bipartitions gave out tota…
Detecting underlying symmetry-protected topological phases via strange correlators and edge engineering
Zhe Wang, Longye Lu, Shang-Qiang Ning +4
The vast majority of symmetry-protected topological (SPT) states are difficult to detect, which often leads to their misidentification as ordinary or topologically trivial phases.…
