Gap solitons in superfluid boson-fermion mixtures
Sadhan K. Adhikari, Boris A. Malomed
Using coupled equations for the bosonic and fermionic order parameters, we construct families of gap solitons (GSs) in a nearly one-dimensional Bose-Fermi mixture trapped in a peri…
Superfluid Fermi-Fermi mixture: phase diagram, stability, and soliton formation
Sadhan K. Adhikari
We study the phase diagram for a dilute Bardeen-Cooper-Schrieffer superfluid Fermi-Fermi mixture (of distinct mass) at zero temperature using energy densities for the superfluid fe…
One-dimensional superfluid Bose-Fermi mixture: mixing, demixing and bright solitons
Sadhan K. Adhikari, Luca Salasnich
We study a ultra-cold and dilute superfluid Bose-Fermi mixture confined in a strictly one-dimensional atomic waveguide by using a set of coupled nonlinear mean-field equations obta…
Mixing-demixing transition and collapse of a vortex state in a quasi-two-dimensional boson-fermion mixture
Sadhan K. Adhikari, Luca Salasnich
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 quan…
Formation of bright solitons and soliton trains in a fermion-fermion mixture by modulational instability
Sadhan K. Adhikari
We employ a time-dependent mean-field-hydrodynamic model to study the generation of bright solitons in a degenerate fermion-fermion mixture in a cigar-shaped geometry using variati…
Finite-well potential in the 3D nonlinear Schroedinger equation: Application to Bose-Einstein condensation
Sadhan K. Adhikari
Using variational and numerical solutions we show that stationary negative-energy localized (normalizable) bound states can appear in the three-dimensional nonlinear Schrödinger eq…
