Quantum Fisher information of magnetic quantum phase transition on Kondo lattice
Yuan Fang, Lei Chen, Mounica Mahankali +4
Strange metals exemplify highly collective quantum many-body systems that call for new means of characterization, and there is considerable potential for quantum information approa…
Topology and compact molecular orbitals in twisted bilayer WSe
Chenyuan Li, Rwik Dutta, Fang Xie +4
Recent observations of superconductivity in twisted bilayer WSe (tWSe) have motivated theoretical proposals for unconventional pairing mechanisms. A central question is whe…
Chiral Weyl-Kondo semimetals and hexagonal heavy fermion systems
Kuan-Sen Lin, Yuan Fang, Henrique Fabrelli +7
Strong correlation, in concert with symmetry and topology, engenders novel gapless phases of matter, though only a tip of the iceberg has been seen. An exemplary framework is provi…
Signatures of Green's function zeros and their topology using impurity spectroscopy
Sayan Mitra, Fang Xie, Marek Kolmer +2
Topology without quasiparticles has emerged as a key framework for understanding Mott insulators, where Green's-function zeros encode nontrivial topological structure. Yet, experim…
Spin Excitations and Flat Electronic Bands in a Cr-based Kagome Superconductor
Zehao Wang, Yucheng Guo, Hsiao Yu Huang +33
In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs)…
Topological chiral superconductivity from antiferromagnetic correlations in moiré bands with extreme spin-orbit coupling
Chenyuan Li, Fang Xie, Jennifer Cano +1
Motivated by the strong-correlation phenomenology observed near the superconducting phase in twisted bilayer WSe, we study multi-orbital - models that are derived from di…
