Precise computation of universal corner entanglement entropy at 2+1 dimension: From Ising to Gaussian quantum critical points
Ben Lee-Yeung Ngai, Justin Tim-Lok Chau, Junchen Rong +3
Computing the subleading logarithmic term in the entanglement entropy (EE) of (2+1)d quantum many-body systems remains a significant challenge, despite its central role in revealin…
Numerical evidence of a critical point in the (2+1)D SO(5) nonlinear sigma model with Wess-Zumino-Witten term
Yuan Da Liao, Bin-Bin Chen, Fakher F. Assaad +3
We develop an optimized continuous-field quantum Monte Carlo (QMC) algorithm to investigate the projected SO(5) nonlinear sigma model with a Wess-Zumino-Witten term, which describe…
Universal term of Entanglement Entropy in the -flux Hubbard model
Yuan Da Liao
Researchers in physical science aim to uncover universal features in strongly interacting many-body systems, often hidden in complicated observables like entanglement entropy (EE).…
Quasiparticle Spectroscopy of Chiral Charge Order
Jiangchang Zheng, Caiyun Chen, Gaopei Pan +11
Electronic interactions can give rise to novel charge density waves with unconventional ground states. Recent experiments report evidence for a chiral charge density wave (CDW) tha…
