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…
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-…
Scaling of entanglement entropy at deconfined quantum criticality
Jiarui Zhao, Yan-Cheng Wang, Zheng Yan +2
We develop a nonequilibrium increment method to compute the Rényi entanglement entropy and investigate its scaling behavior at the deconfined critical (DQC) point via large-scale q…
Emergent Rokhsar-Kivelson point in realistic quantum Ising models
Zheng Zhou, Zheng Yan, Changle Liu +2
We show that the Rokhsar-Kivelson (RK) point in quantum dimer models (QDM) can emerge in realistic quantum Ising spin systems. Specifically, we investigate the -- tr…
Quantum optimization within lattice gauge theory model on a quantum simulator
Zheng Yan, Zheng Zhou, Yan-Hua Zhou +4
Simulating lattice gauge theory (LGT) Hamiltonian and its nontrivial states by programmable quantum devices has attracted numerous attention in recent years. Rydberg atom arrays co…
Phase Diagram of Triangular Lattice Quantum Ising Model under External Field
Yuan Da Liao, Han Li, Zheng Yan +4
Quantum Ising model on a triangular lattice hosts a finite temperature Berezinskii-Kosterlitz-Thouless (BKT) phase with emergent U(1) symmetry, and it will transit into an up-up-do…
