Spectroscopic evidence for possible quantum spin liquid behavior in a two-dimensional Mott insulator
Haiyang Chen, Fo-Hong Wang, Qiang Gao +6
Mott insulators with localized magnetic moments will exhibit a quantum spin liquid (QSL) state when the quantum fluctuations are strong enough to suppress the ordering of the spins…

Twisted Rényi Negativity as a Reliable Proxy for Mixed-State Entanglement in Fermionic Systems
Fo-Hong Wang, Xiao Yan Xu
Characterizing mixed-state entanglement in fermionic quantum matter represents a fundamental challenge at the intersection of condensed matter physics and quantum information. Unli…
