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…
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…
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…
