Anomalous Diffusion and Superdiffusion in Integrable Spin Chains via a Soliton Gas Mapping
Andrew Urilyon, Romain Vasseur, Sarang Gopalakrishnan +1
We introduce a multi-species soliton gas in which each species has a distinct effective scattering length, and the repulsive scattering shift is set by the smaller of the two colli…

Ballistic macroscopic fluctuation theory via mapping to point particles
Jitendra Kethepalli, Andrew Urilyon, Tridib Sadhu +1
Ballistic Macroscopic Fluctuation Theory (BMFT) captures the evolution of fluctuations and correlations in systems where transport is strictly ballistic. We show that, for \emph{ge…

Simulating generalised fluids via interacting wave packets evolution
Andrew Urilyon, Leonardo Biagetti, Jitendra Kethepalli +1
One-dimensional integrable and quasi-integrable systems display, on macroscopic scales, a universal form of transport known as Generalized Hydrodynamics (GHD). In its standard Eule…
