Symmetries as Ground States of Local Superoperators: Hydrodynamic Implications
Sanjay Moudgalya, Olexei I. Motrunich
Symmetry algebras of quantum many-body systems with locality can be understood using commutant algebras, which are defined as algebras of operators that commute with a given set of…
Edge states of 2D time-reversal-invariant topological superconductors with strong interactions and disorder: A view from the lattice
Jun Ho Son, Jason Alicea, Olexei I. Motrunich
Two-dimensional time-reversal-invariant topological superconductors host helical Majorana fermions at their boundary. We study the fate of these edge states under the combined infl…
Robustness and eventual slow decay of bound states of interacting microwave photons in the Google Quantum AI experiment
Federica Maria Surace, Olexei Motrunich
Integrable models are characterized by the existence of stable excitations that can propagate indefinitely without decaying. This includes multi-magnon bound states in the celebrat…
Exotic quantum liquids in Bose-Hubbard models with spatially-modulated symmetries
Pablo Sala, Yizhi You, Johannes Hauschild +1
We investigate the effect that spatially modulated continuous conserved quantities can have on quantum ground states. We do so by introducing a family of one-dimensional local quan…
Weak integrability breaking perturbations of integrable models
Federica Maria Surace, Olexei Motrunich
A quantum integrable system slightly perturbed away from integrability is typically expected to thermalize on timescales of order , where is the perturbation stre…
Numerical Methods for Detecting Symmetries and Commutant Algebras
Sanjay Moudgalya, Olexei I. Motrunich
For families of Hamiltonians defined by parts that are local, the most general definition of a symmetry algebra is the commutant algebra, i.e., the algebra of operators that commut…
