Resolving Quantum Criticality in the Honeycomb Hubbard Model
Fo-Hong Wang, Fanjie Sun, Chenghao He +1
Quantum phase transitions driven by electronic correlations are central to understanding the physics of graphene and related two-dimensional materials. A paradigmatic example is th…
Stabilizer-Rényi Microscopy of Critical Correlations in Interacting Fermions
Jun Qi Fang, Fo-Hong Wang, Xiao Yan Xu
Quantum magic---the resource that separates universal quantum computation from efficiently simulable Clifford circuits---has emerged as a diagnostic of many-body quantum states, ye…
Untwisted and Twisted Rényi Negativities: Toward a Rényi Proxy for Logarithmic Negativity in Fermionic Systems
Fo-Hong Wang, Xiao Yan Xu
Entanglement entropy is a fundamental measure of quantum entanglement for pure states, but for large-scale many-body systems, Rényi entanglement entropy is much more computational…
Chiral excitation flows of a multinode network based on synthetic gauge fields
Xian-Liang Lu, Fo-Hong Wang, Jia-Jin Zou +1
Chiral excitation flows have attracted significant attention due to their unique unidirectionality. Such flows have been studied in three-node networks with synthetic gauge fields…
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…
Entanglement Rényi Negativity of Interacting Fermions from Quantum Monte Carlo Simulations
Fo-Hong Wang, Xiao Yan Xu
Many-body entanglement unveils additional aspects of quantum matter and offers insights into strongly correlated physics. While ground-state entanglement has received much attentio…
