Measuring Rényi entanglement entropy with high efficiency and precision in quantum Monte Carlo simulations
Jiarui Zhao, Bin-Bin Chen, Yan-Cheng Wang +3
We develop a nonequilibrium increment method in quantum Monte Carlo simulations to obtain the Rényi entanglement entropy of various quantum many-body systems with high efficiency a…
Fermion sign bounds theory in quantum Monte Carlo simulation
Xu Zhang, Gaopei Pan, Xiao Yan Xu +1
Sign problem in fermion quantum Monte Carlo (QMC) simulation appears to be an extremely hard problem. Traditional lore passing around for years tells people that when there is a si…
Unlocking the general relationship between energy and entanglement spectra via the wormhole effect
Zheng Yan, Zi Yang Meng
Based on the path integral formulation of the reduced density matrix, we develop a scheme to overcome the exponential growth of computational complexity in reliably extracting low-…
Superconductivity and bosonic fluid emerging from Moiré flat bands
Xu Zhang, Kai Sun, Heqiu Li +2
Although evidence of inter-valley attraction-mediated by phonon or topological fluctuations is accumulating, the origin of superconductivity in the flat-band quantum moiré material…
Nematic Quantum Criticality in Dirac Systems
Jonas Schwab, Lukas Janssen, Kai Sun +4
We investigate nematic quantum phase transitions in two different Dirac fermion models. The models feature twofold and fourfold, respectively, lattice rotational symmetries that ar…
Dynamical properties of collective excitations in twisted bilayer Graphene
Gaopei Pan, Xu Zhang, Heqiu Li +2
Employing the recently developed momentum-space quantum Monte Carlo scheme, we study the dynamic response of single-particle and collective excitations in realistic continuum model…
