Super-Tonks-Girardeau Quench in the Extended Bose-Hubbard Model
Maciej Marciniak, Maciej Åebek, Jakub KopyciÅski +3
We investigate the effect of a quench from a one-dimensional gas with strong and repulsive local interactions to a strongly attractive one, known as the super-Tonks-Girardeau effec…
Chapman-Enskog theory and crossover between diffusion and superdiffusion for nearly integrable quantum gases
Maciej Åebek, MiÅosz Panfil
Integrable systems feature an infinite number of conserved charges and on hydrodynamic scales are described by generalised hydrodynamics (GHD). This description breaks down when th…
Phase diagram and elementary excitations of strongly interacting droplets with non-local interactions
Maciej Åebek, Jakub KopyciÅski, Wojciech Górecki +2
A one-dimensional bosonic gas with strong contact repulsion and attractive non-local interactions may form a quantum droplet with a flat-top density profile. We focus on a system i…
Navier-Stokes equations for nearly integrable quantum gases
Maciej Åebek, MiÅosz Panfil
The Navier-Stokes equations are paradigmatic equations describing hydrodynamics of an interacting system with microscopic interactions encoded in transport coefficients. In this wo…
