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 b…

Detecting Symmetry-Resolved Entanglement: A Quantum Monte Carlo Approach
Kuangjie Chen, Weizhen Jia, Xiaopeng Li +2
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…
