Hall conductivity reveals the nature of quantum coherence in strongly correlated metals
Emily Z. Zhang, Thomas P. Devereaux
Linear-in-temperature resistivity is a hallmark for strange metallic transport, and appears universally in many strongly correlated electron systems. However, the focus on the long…
Electric field control of a quantum spin liquid in weak Mott insulators
Daniel J. Schultz, Alexandre Khoury, Félix Desrochers +3
The triangular lattice Hubbard model at strong coupling, whose effective spin model contains both Heisenberg and ring exchange interactions, exhibits a rich phase diagram as the ra…
Disentangling spin excitation continua in classical and quantum magnets using 2D nonlinear spectroscopy
Emily Z. Zhang, Ciarán Hickey, Yong Baek Kim
Inelastic neutron scattering (INS) has traditionally been one of the primary methods for investigating quantum magnets, particularly in identifying a continuum of excitations as a…
Spin excitation continuum to topological magnon crossover and thermal Hall conductivity in Kitaev magnets
Emily Z. Zhang, Reja H. Wilke, Yong Baek Kim
There has been great interest in identifying a Kitaev quantum spin liquid state in frustrated magnets with bond-dependent interactions. In particular, the experimental report of a…
Intrinsic Thermal Hall Effect in Mott Insulators
Jixun K. Ding, Emily Z. Zhang, Wen O. Wang +4
In light of recent experimental data indicating a substantial thermal Hall effect in square lattice antiferromagnetic Mott insulators, we investigate whether a simple Mott insulato…
Detection of chiral spin fluctuations driven by frustration in Mott insulators
Kuan H. Hsu, Chunjing Jia, Emily Z. Zhang +4
Topologically ordered states, such as chiral spin liquids, have been proposed as candidates that host fractionalized excitations. However, detecting chiral character or proximity t…
