Theory of competing excitonic orders in insulating WTe monolayers
Yves H. Kwan, T. Devakul, S. L. Sondhi +1
We develop a theory of the excitonic phase recently proposed as the zero-field insulating state observed near charge neutrality in monolayer WTe. Using a Hartree-Fock approxima…
Superuniversality from disorder at two-dimensional topological phase transitions
Byungmin Kang, S. A. Parameswaran, Andrew C. Potter +2
We investigate the effects of quenched randomness on topological quantum phase transitions in strongly interacting two-dimensional systems. We focus first on transitions driven by…
Asymptotically exact theory for nonlinear spectroscopy of random quantum magnets
S. A. Parameswaran, Sarang Gopalakrishnan
We study nonlinear response in quantum spin systems {near infinite-randomness critical points}. Nonlinear dynamical probes, such as two-dimensional (2D) coherent spectroscopy, can…
Spin crossovers and superdiffusion in the one-dimensional Hubbard model
Michele Fava, Brayden Ware, Sarang Gopalakrishnan +2
We use tools from integrability and generalized hydrodynamics to study finite-temperature dynamics in the one-dimensional Hubbard model. First, we examine charge, spin, and energy…
Glide symmetry breaking and Ising criticality in the quasi-1D magnet CoNbO
Michele Fava, Radu Coldea, S. A. Parameswaran
We construct a microscopic spin-exchange Hamiltonian for the quasi-1D Ising magnet CoNbO that captures detailed and hitherto-unexplained aspects of its dynamic spin structu…
