Limitation of the Lee-Huang-Yang interaction in forming a self-bound state in Bose-Einstein condensates

Gautam, S.; Adhikari, S.K. (2019-12-05)

The perturbative Lee-Huang-Yang (LHY) interaction proportional to n 3/2 , where n is the density, creates an infinitely repulsive potential at the center of a Bose-Einstein condensate (BEC) with net attraction, which ...
Supersolid-like solitons in a spin-orbit-coupled spin-2 condensate

Kaur, P.; Gautam, S.; Adhikari, S.K. (2022-06-22)

We study supersolid-like crystalline structures emerging in the stationary states of a quasi-two-dimensional spin-orbit (SO)-coupled spin-2 condensate in the ferromagnetic, cyclic, and antiferromagnetic phases by solving ...
Supersolid-like solitons in two-dimensional nonmagnetic spin-orbit coupled spin-1 and spin-2 condensates

Kaur, P.; Gautam, S.; Adhikari, S.K. (2022-12-15)

We demonstrate spontaneous generation of spatially-periodic supersolid-like super-lattice and stripesolitons in Rashba spin-orbit (SO) coupled spin-1 and spin-2 quasi-two-dimensional nonmagnetic BoseEinstein condensates ...
Weak-coupling to unitarity crossover in bose-fermi mixtures: mixing-demixing and spontaneous symmetry breaking in trapped systems

Gautam, S.; Adhikari, S.K. (2019-12-26)

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 Lee-HuangYang (LHY) corrections. We suggest ...
