Unconventional Quantum Criticality in Long-Range Spin-1 Chains: Insights from Entanglement Entropy and Bipartite Fluctuations
Justin Tim-Lok Chau, Jiarui Zhao, Nicolas Laflorencie +1
We study the ground-state phase diagram of a spin-1 Heisenberg chain with staggered long-range (LR) interactions decaying as using a quantum Monte Carlo approach…
Detecting Symmetry-Resolved Entanglement: A Quantum Monte Carlo Approach
Kuangjie Chen, Weizhen Jia, Xiaopeng Li +3
Symmetry and entanglement are two fundamental concepts in quantum many-body physics. Their interplay is captured by symmetry-resolved entanglement, which decomposes the total entan…
Scaling of Disorder Operator and Entanglement Entropy at Easy-Plane Deconfined Quantum Criticalities
Jiarui Zhao, Zi Yang Meng, Yan-Cheng Wang +1
We systematically investigate the scaling behaviors of the disorder operator and the entanglement entropy (EE) of the easy-plane JQ (EPJQ) model at its transitions between the anti…
Extracting Universal Corner Entanglement Entropy during the Quantum Monte Carlo Simulation
Yuan Da Liao, Menghan Song, Jiarui Zhao +1
The subleading corner logarithmic corrections in entanglement entropy (EE) are crucial for revealing universal characteristics of the quantum critical points (QCPs), but they are c…
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…
Unconventional Scalings of Quantum Entropies in Long-Range Heisenberg Chains
Jiarui Zhao, Nicolas Laflorencie, Zi Yang Meng
In this work, building on state-of-the-art quantum Monte Carlo simulations, we perform systematic finite-size scaling of both entanglement and participation entropies for long-rang…
