Subdiffusive hydrodynamics of nearly-integrable anisotropic spin chains
Jacopo De Nardis, Sarang Gopalakrishnan, Romain Vasseur +1
We address spin transport in the easy-axis Heisenberg spin chain subject to integrability-breaking perturbations. We find that spin transport is subdiffusive with dynamical exponen…
Subdiffusion and many-body quantum chaos with kinetic constraints
Hansveer Singh, Brayden Ware, Romain Vasseur +1
We investigate the spectral and transport properties of many-body quantum systems with conserved charges and kinetic constraints. Using random unitary circuits, we compute ensemble…
Operator front broadening in chaotic and integrable quantum chains
Javier Lopez-Piqueres, Brayden Ware, Sarang Gopalakrishnan +1
Operator spreading under unitary time evolution has attracted a lot of attention recently, as a way to probe many-body quantum chaos. While quantities such as out-of-time-ordered c…
Stability of superdiffusion in nearly integrable spin chains
Jacopo De Nardis, Sarang Gopalakrishnan, Romain Vasseur +1
Superdiffusive finite-temperature transport has been recently observed in a variety of integrable systems with nonabelian global symmetries. Superdiffusion is caused by giant Golds…
Local integrals of motion and the quasiperiodic many-body localization transition
Hansveer Singh, Brayden Ware, Romain Vasseur +1
We study the many body localization (MBL) transition for interacting fermions subject to quasiperiodic potentials by constructing the local integrals of motion (LIOMs) in the MBL p…
