Weak-coupling to unitarity crossover in Bose-Fermi mixtures: Mixing-demixing and spontaneous symmetry breaking in trapped systems
Sandeep Gautam, S. K. Adhikari
The usual treatment of a Bose-Fermi mixture relies on weak-coupling Gross-Pitaevskii (GP) and density-functional (DF) Lagrangians, often including the more realistic {perturbative}…
Limitation of the Lee-Huang-Yang interaction in forming a self-bound state in Bose-Einstein condensates
Sandeep Gautam, S. K. Adhikari
The perturbative Lee-Huang-Yang (LHY) interaction proportional to , where is the density, creates an infinitely repulsive potential at the center of a Bose-Einstein co…
Three-dimensional vortex-bright solitons in a spin-orbit coupled spin- condensate
Sandeep Gautam, S. K. Adhikari
We demonstrate stable and metastable vortex-bright solitons in a three-dimensional spin-orbit-coupled three-component hyperfine spin-1 Bose-Einstein condensate (BEC) using numerica…
Vortex-bright solitons in a spin-orbit coupled spin- condensate
Sandeep Gautam, S. K. Adhikari
We study the vortex-bright solitons in a quasi-two-dimensional spin-orbit-coupled (SO-coupled) hyperfine spin-1 three-component Bose-Einstein condensate (BEC) using variational met…
Fractional-charge vortex in a spinor Bose-Einstein condensate
Sandeep Gautam, S. K. Adhikari
We classify all possible fractional charge vortices of charge less than unity in spin-1 and spin-2 polar and cyclic Bose-Einstein condensates (BECs) with zero magnetization. Static…
Analytic models for density of a ground-state spinor condensate
Sandeep Gautam, S. K. Adhikari
We demonstrate that the ground state of a trapped spin-1 and spin-2 spinor ferromagnetic Bose-Einstein condensate (BEC) can be well approximated by a single decoupled Gross-Pitaevs…
