Addressing general measurements in quantum Monte Carlo
Zhiyan Wang, Zenan Liu, Bin-Bin Mao +2
Quantum Monte Carlo is one of the most promising approaches for dealing with large-scale quantum many-body systems. It has played an extremely important role in understanding stron…
Sudden change in entanglement Hamiltonian: Phase diagram of an Ising entanglement Hamiltonian
Zhe Wang, Siyi Yang, Bin-Bin Mao +2
The form of the entanglement Hamiltonian varies with the parameters of the original system. Whether there is a singularity is the key problem for demonstrating/negating the univers…
High-efficiency quantum Monte Carlo algorithm for extracting entanglement entropy in interacting fermion systems
Weilun Jiang, Gaopei Pan, Zhe Wang +3
The entanglement entropy probing novel phases and phase transitions numerically via quantum Monte Carlo has made great achievements in large-scale interacting spin/boson systems. I…
Tracking the variation of entanglement Rényi negativity: a quantum Monte Carlo study
Yi-Ming Ding, Yin Tang, Zhe Wang +3
Entanglement entropy has been a powerful tool for analyzing phases and criticality in pure ground states via quantum Monte Carlo (QMC). However, mixed-state entanglement, relevant…
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…
Bipartite reweight-annealing algorithm of quantum Monte Carlo to extract large-scale data of entanglement entropy and its derivative
Zhe Wang, Zhiyan Wang, Yi-Ming Ding +2
We propose a quantum Monte Carlo scheme capable of extracting large-scale data of Rényi entanglement entropy (EE) with high precision and low technical barrier. Instead of directly…
Surface phase transitions in a (1+1)-dimensional conformal field theory boundary coupled to a (2+1)-dimensional bulk
Zhe Wang, Shang-Qiang Ning, Zenan Liu +4
We design a (2+1))-dimensional [(2+1)D] quantum spin model in which spin-1/2 ladders are coupled through antiferromagnetic Ising interactions. The model hosts a quantum phase trans…
