Phase diagram of rotating Bose-Einstein condensates trapped in power-law and hard-wall potentials
G. M. Kavoulakis
We investigate the rotational phase diagram of a quasi-two-dimensional, weakly-interacting Bose-Einstein condensate confined in power-law and in hard-wall trapping potentials. For…
Excitation spectrum of a bright solitary wave in a Bose-Einstein condensate and its connection with the Higgs and the Goldstone modes
G. M. Kavoulakis
We consider the problem of Bose-Einstein condensed atoms, which are confined in a (quasi) one-dimensional toroidal potential. We focus on the case of an effective attractive intera…
Rotating quantum droplets confined in a harmonic potential
S. Nikolaou, G. M. Kavoulakis, M. Ogren
We investigate the rotational properties of a two-component, two-dimensional self-bound quantum droplet, which is confined in a harmonic potential and compare them with the well-kn…
Superfluid-droplet crossover in a binary boson mixture on a ring: Exact diagonalization solutions for few-particle systems in one dimension
L. Chergui, J. Bengtsson, J. Bjerlin +3
We investigate the formation of self-bound quantum droplets in a one-dimensional binary mixture of bosonic atoms, applying the method of numerical diagonalization of the full Hamil…
Stationary states of Bose-Einstein condensed atoms rotating in an asymmetric ring potential
M. Ögren, Giannis Drougakis, Giorgos Vasilakis +2
We consider a Bose-Einstein condensate, which is confined in a very tight toroidal/annular trap, in the presence of a potential, which breaks the axial symmetry of the Hamiltonian.…
Many-body state and dynamic behaviour of the pair-correlation function of a small Bose-Einstein condensate confined in a ring potential
A. Roussou, J. Smyrnakis, M. Magiropoulos +1
We investigate the many-body state and the static and the dynamic behaviour of the pair-correlation function of a Bose-Einstein condensate with a finite atom number, which is confi…
