Extracting subleading corrections in entanglement entropy at quantum phase transitions
Menghan Song, Jiarui Zhao, Zi Yang Meng +2
We systematically investigate the finite size scaling behavior of the Rényi entanglement entropy (EE) of several representative 2d quantum many-body systems between a subregion and…
Resummation-based Quantum Monte Carlo for Entanglement Entropy Computation
Menghan Song, Ting-Tung Wang, Zi Yang Meng
Based on the recently developed resummation-based quantum Monte Carlo method for the SU() spin and loop-gas models, we develop a new algorithm, dubbed ResumEE, to compute the en…
Disorder Operator and Rényi Entanglement Entropy of Symmetric Mass Generation
Zi Hong Liu, Yuan Da Liao, Gaopei Pan +8
In recent years a consensus has gradually been reached that the previously proposed deconfined quantum critical point (DQCP) for spin-1/2 systems, an archetypal example of quantum…
Evolution of entanglement entropy at SU() deconfined quantum critical points
Menghan Song, Jiarui Zhao, Meng Cheng +4
Over the past two decades, the enigma of the deconfined quantum critical point (DQCP) has attracted broad attention across the condensed matter, quantum field theory, and high-ener…
Quantum criticality and entanglement for two dimensional long-range Heisenberg bilayer
Menghan Song, Jiarui Zhao, Yang Qi +2
The study of quantum criticality and entanglement in systems with long-range (LR) interactions is still in its early stages, with many open questions remaining. In this work, we in…
Finite-temperature critical behaviors in 2D long-range quantum Heisenberg model
Jiarui Zhao, Menghan Song, Yang Qi +2
The Mermin-Wagner theorem states that spontaneous continuous symmetry breaking is prohibited in systems with short-range interactions at spatial dimension . For long-range…
Dynamical properties of quantum many-body systems with long range interactions
Menghan Song, Jiarui Zhao, Chengkang Zhou +1
Employing large-scale quantum Monte Carlo simulations, we systematically compute the energy spectra of the 2D spin-1/2 Heisenberg model with long-range interactions. With the $1/r^…
