Spontaneous continuous-symmetry breaking and tower of states in a comb chain
Jingya Wang, Zenan Liu, Bin-Bin Mao +4
Based on the study of a one-dimensional (1D) antiferromagnetic Heisenberg model on a comb lattice, this work identifies an example of spontaneous continuous symmetry breaking in a…
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…
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…
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…
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…
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 directl…
