Absolutely Stable Spatiotemporal Order in Noisy Quantum Systems
Max McGinley, Sthitadhi Roy, S. A. Parameswaran
We introduce a model of non-unitary quantum dynamics that exhibits infinitely long-lived discrete spatiotemporal order robust against any unitary or dissipative perturbation. Ergod…
High-temperature transport and polaron speciation in the anharmonic Holstein model
Attila Szabó, S. A. Parameswaran, Sarang Gopalakrishnan
We study the finite-temperature transport of electrons coupled to anharmonic local phonons. Our focus is on the high-temperature incoherent regime, where controlled calculations ar…
Beyond the Freshman's Dream: Classical fractal spin liquids from matrix cellular automata in three-dimensional lattice models
Sounak Biswas, Yves H. Kwan, S. A. Parameswaran
We construct models hosting classical fractal spin liquids on two realistic three-dimensional (3D) lattices of corner-sharing triangles: trillium and hyperhyperkagome (HHK). Both m…
One-Dimensional Luttinger Liquids in a Two-Dimensional Moiré Lattice
Pengjie Wang, Guo Yu, Yves H. Kwan +13
The Luttinger liquid (LL) model of one-dimensional (1D) electronic systems provides a powerful tool for understanding strongly correlated physics including phenomena such as spin-c…
Kekulé spiral order at all nonzero integer fillings in twisted bilayer graphene
Yves H. Kwan, Glenn Wagner, Tomohiro Soejima +4
We study magic angle graphene in the presence of both strain and particle-hole symmetry breaking due to non-local inter-layer tunneling. We perform a self-consistent Hartree-Fock s…
Hydrodynamic non-linear response of interacting integrable systems
Michele Fava, Sounak Biswas, Sarang Gopalakrishnan +2
We develop a formalism for computing the non-linear response of interacting integrable systems. Our results are asymptotically exact in the hydrodynamic limit where perturbing fiel…
