Kohler's Rule Holds in the Strange Metallic Hubbard Model
Rebekah M. Jin, Emily Z. Zhang, Jixun K. Ding +2
Unconventional magnetotransport violating Kohler's rule has been reported in many strongly correlated strange metals, but the exact origin of these violations is yet unknown. To in…
Robust Strange Metallicity across Attractive and Repulsive Hubbard Models
Xiaoyue Ma, Emily Z. Zhang, Thomas P. Devereaux
Using determinant quantum Monte Carlo simulations, we compare charge transport in the two-dimensional attractive and repulsive Hubbard models at strong coupling, . Althoug…
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…
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…
Microscopic Roadmap to a Yao-Lee Spin-Orbital Liquid
Derek Churchill, Emily Z. Zhang, Hae-Young Kee
The exactly solvable spin-1/2 Kitaev model on a honeycomb lattice has drawn significant interest, as it offers a pathway to realizing the long-sought after quantum spin liquid. Bui…
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…
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…
Quantum Fluctuations Suppress the Critical Fields in BaCo(AsO)
Shiva Safari, William Bateman-Hemphill, Asimpunya Mitra +10
Early efforts to realize exotic quantum ground states in frustrated magnets focused on frustration arising from the lattice geometry alone. Attention has shifted to bond-dependent…
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…
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…
Geometrical frustration versus Kitaev interactions in BaCo(AsO)
Thomas Halloran, Félix Desrochers, Emily Z. Zhang +12
Recently, Co-based honeycomb magnets have been proposed as promising candidate materials to host the Kitaev spin liquid state. One of the front-runners is BaCo(AsO) (BC…
Uncovering footprints of dipolar-octupolar quantum spin ice from neutron scattering signatures
Masashi Hosoi, Emily Z. Zhang, Adarsh S. Patri +1
Recent experiments on CeZrO suggest that this material may host a novel form of quantum spin ice, a three-dimensional quantum spin liquid with an emergent photon. The C…
Dynamical Signatures of Rank-2 Spin Liquids
Emily Z. Zhang, Finn Lasse Buessen, Yong Baek Kim
Emergent gauge theories and artificial photons in frustrated magnets are outstanding examples of many-body collective phenomena. The classical and quantum regimes of these s…
Topological magnons for thermal Hall transport in frustrated magnets with bond-dependent interactions
Emily Z. Zhang, Li Ern Chern, Yong Baek Kim
Thermal transport in topologically-ordered phases of matter provides valuable insights as it can detect the charge-neutral quasiparticles that would not directly couple to electrom…
