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 paper models the magnetic order in the bilayer nickelate La₃Ni₂O₇ as arising from local moments interacting via combined RKKY and superexchange couplings, predicting a wavevect…
Nonlinear thermal and thermoelectric transport from quantum geometry
Yuan Fang, Shouvik Sur, Yonglong Xie +1
Quantum geometry may enable the development of quantum phases ranging from superconductivity to correlated topological states. One powerful probe of quantum geometry is the nonline…
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…
Uniaxial strain tuned magnetism of the altermagnet candidate h-FeS
Weiliang Yao, Feng Ye, Zachary J. Morgan +9
Altermagnets are collinear magnetic materials with 'alter'nating local crystalline environments, characterized by joint spin and crystalline symmetries that enable ferromagnetic-li…
