Complete finite-size scaling theory of Renyi thermal entropy for second, first and weak first order quantum phase transitions
Zhe Wang, Yanzhang Zhu, Yi-Ming Ding +2
Establishing the nature of a quantum phase transition in finite-size simulations -- whether continuous, first-order, or weak first-order -- is a fundamental challenge in quantum ma…
Evaluating many-body stabilizer Rényi entropy by sampling reduced Pauli strings: singularities, volume law, and nonlocal magic
Yi-Ming Ding, Zhe Wang, Zheng Yan
We present a novel quantum Monte Carlo method for evaluating the -stabilizer Rényi entropy (SRE) for any integer . By interpreting -SRE as partition function ratios,…
Tracking the variation of entanglement Rényi negativity: a quantum Monte Carlo study
Yi-Ming Ding, Yin Tang, Zhe Wang +3
Entanglement entropy has been a powerful tool for analyzing phases and criticality in pure ground states via quantum Monte Carlo (QMC). However, mixed-state entanglement, relevant…
Universal Behavior in Entanglement Entropy Reveals Quantum Criticality and Underlying Symmetry Breaking
Zhe Wang, Zehui Deng, Zenan Liu +5
Entanglement plays a key role in quantum physics, but how much information it can extract from many-body systems is still an open question, particularly regarding quantum criticali…
