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…
Magnetic Order in bilayer Ruddlesden-Popper Nickelates
Yiming Wang, Guijing Duan, Zhiguang Liao +3
The recent discovery of high-temperature superconductivity in the bilayer nickelate LaNiO has led to extensive interest in the correlation physics of its normal state.…
Nonperturbative Nonlinear Hall Effect in Nonequilibrium Steady States
Lei Geng, Martin Eckstein, Lei Chen +4
The nonlinear Hall effect in quantum materials has attracted broad interest, yet most existing studies focus on the weak-field, perturbative regime. Here we develop a nonperturbati…
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…
