Droplet to soliton crossover at negative temperature in presence of bi-periodic optical lattices
Abstract It is shown that the phenomenon of negative temperature essentially occurs in Bose-Einstein condensate due to the realization of the upper bound energy state utilizing a combination of expulsive harmonic oscillator and optical lattice potentials. We study the existence of quantum droplets a...
