Navier-Stokes equations for nearly integrable quantum gases
Maciej Łebek, Miłosz Panfil
The Navier-Stokes equations are paradigmatic equations describing hydrodynamics of an interacting system with microscopic interactions encoded in transport coefficients. In this wo…
Super-Tonks-Girardeau Quench in the Extended Bose-Hubbard Model
Maciej Marciniak, Maciej Łebek, Jakub Kopyciński +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…
Prethermalization in coupled one-dimensional quantum gases
Maciej Łebek, Miłosz Panfil, Robert M. Konik
We consider the problem of the development of steady states in one-dimensional Bose gas tubes that are weakly coupled to one another through a density-density interaction. We analy…
Phase diagram and elementary excitations of strongly interacting droplets with non-local interactions
Maciej Łebek, Jakub Kopyciński, 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…
Ultrawide dark solitons and droplet-soliton coexistence in a dipolar Bose gas with strong contact interactions
Jakub Kopyciński, Maciej Łebek, Wojciech Górecki +1
We look into dark solitons in a quasi-1D dipolar Bose gas and in a quantum droplet. We derive the analytical solitonic solution of a Gross-Pitaevskii-like equation accounting for b…
Repulsive dynamics of strongly attractive one-dimensional quantum gases
Maciej Łebek, Andrzej Syrwid, Piotr T. Grochowski +1
We analyze the dynamics of one-dimensional quantum gases with strongly attractive contact interactions. We specify a class of initial states for which attractive forces effectively…
Beyond Gross-Pitaevskii equation for 1D gas: quasiparticles and solitons
Jakub Kopyciński, Maciej Łebek, Maciej Marciniak +3
Describing properties of a strongly interacting quantum many-body system poses a serious challenge both for theory and experiment. In this work, we study excitations of one-dimensi…
Many-body molecule formation at a domain wall in a one-dimensional strongly interacting ultracold Fermi gas
Andrzej Syrwid, Maciej Łebek, Piotr T. Grochowski +1
We analyze how the presence of the bound state on top of strong intercomponent contact repulsion affects the dynamics of a two-component ultracold Fermi gas confined in a one-dimen…
Thermodynamic Casimir forces in strongly anisotropic systems within the class
Maciej Łebek, Paweł Jakubczyk
We analyze the thermodynamic Casimir effect in strongly anizotropic systems from the vectorial class in a slab geometry. Employing the imperfect (mean-field) Bose gas…
