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…
Robustness of Magic in the quantum Ising chain via Quantum Monte Carlo tomography
Hari Timsina, Yi-Ming Ding, Emanuele Tirrito +5
We study the behavior of magic as a bipartite correlation in the quantum Ising chain across its quantum phase transition, and at finite temperature. In order to quantify the magic…
Detecting (emergent) continuous symmetry of criticality via subsystem's entanglement spectrum
Bin-Bin Mao, Zhe Wang, Bin-Bin Chen +1
The (emergent) symmetry of a critical point is one of the most important information to identify the universality class and effective field theory, which is fundamental for various…
Identifying two-dimensional topological phase transition by entanglement spectrum : A fermion Monte Carlo study
Weilun Jiang, Xiaofan Luo, Bin-Bin Mao +1
Among many types of quantum entanglement properties, the entanglement spectrum provides more abundant information than other observables. Exact diagonalization and density matrix r…
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…
