Solitons are ubiquitous phenomena that appear, among others, in the description of tsunami
waves, fiber-optic communication and ultracold atomic gases. The latter systems turned out …

We numerically study the transport properties of a two-dimensional Fermi gas in a weakly
and strongly interacting regimes, in the range of temperatures close to the transition to a …

The dynamics of linear and nonlinear excitations in a Bose gas in the Tonks-Girardeau
regime with longitudinal confinement are studied within a mean-field theory of quintic …

We characterize the collective modes of a soliton train in a quasi-one-dimensional Fermi
superfluid, using a mean-field formalism. In addition to the expected Goldstone and Higgs …

It is shown that a broad density perturbation in a Fermi (Tonks) cloud takes a shock wave
form in the course of free time evolution. A very accurate analytical description of shock …

Abstract Repulsive Bose–Einstein condensates, where short-range interaction is included
up to the third order by the interaction radius, demonstrate the existence of bright solitons in …

We analyze the ground state of the two-component gas of trapped ultracold fermionic atoms.
We neglect the forces between atoms in the same hyperfine state (the same component) …

We use a time-dependent dynamical mean-field-hydrodynamic model to study the formation
of fermionic dark solitons in a trapped degenerate Fermi gas mixed with a Bose–Einstein …

We investigate the mixing-demixing transition and the collapse in a quasi-two-dimensional
degenerate boson-fermion mixture (DBFM) with a bosonic vortex. We solve numerically a …

The two-component Fermi gas with contact attractive interactions between different spin
components can be described by the Yang-Gaudin model. Applying the Bethe ansatz …
