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…
Superuniversality of superdiffusion
Enej Ilievski, Jacopo De Nardis, Sarang Gopalakrishnan +2
Anomalous finite-temperature transport has recently been observed in numerical studies of various integrable models in one dimension; these models share the feature of being invari…
Hydrodynamics of nonintegrable systems from a relaxation-time approximation
Javier Lopez-Piqueres, Brayden Ware, Sarang Gopalakrishnan +1
We develop a general kinetic theory framework to describe the hydrodynamics of strongly interacting, nonequilibrium quantum systems in which integrability is weakly broken, leaving…
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…
Mean-field entanglement transitions in random tree tensor networks
Javier Lopez-Piqueres, Brayden Ware, Romain Vasseur
Entanglement phase transitions in quantum chaotic systems subject to projective measurements and in random tensor networks have emerged as a new class of critical points separating…
Anomalous low-frequency conductivity in easy-plane XXZ spin chains
Utkarsh Agrawal, Sarang Gopalakrishnan, Romain Vasseur +1
In the easy-plane regime of XXZ spin chains, spin transport is ballistic, with a Drude weight that has a discontinuous fractal dependence on the value of the anisotropy $Δ= \cos πλ…
