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…
Transition from the mean-field to the bosonic Laughlin state in a rotating Bose-Einstein condensate
G. Vasilakis, A. Roussou, J. Smyrnakis +3
We consider a weakly-interacting Bose-Einstein condensate that rotates in either a harmonic, or a weakly-anharmonic trapping potential. Performing numerical calculations, we invest…
Fragility of the Laughlin state in an anharmonically-trapped Bose-Einstein condensate
A. Roussou, J. Smyrnakis, M. Magiropoulos +3
When a Bose-Einstein condensate rotates in a purely harmonic potential with an angular frequency which is close to the trap frequency, its many-body state becomes highly correlated…
Excitation spectrum of a mixture of two Bose gases confined in a ring potential with interaction asymmetry
A. Roussou, J. Smyrnakis, M. Magiropoulos +5
We study the rotational properties of a two-component Bose-Einstein condensed gas of distinguishable atoms which are confined in a ring potential using both the mean-field approxim…
Rotating Bose-Einstein condensates with a finite number of atoms confined in a ring potential: Spontaneous symmetry breaking, beyond the mean-field approximation
A. Roussou, J. Smyrnakis, M. Magiropoulos +2
Motivated by recent experiments on Bose-Einstein condensed atoms which rotate in annular/toroidal traps we study the effect of the finiteness of the atom number on the states o…
Hysteresis and metastability of Bose-Einstein condensed clouds of atoms confined in ring potentials
A. Roussou, G. D. Tsibidis, J. Smyrnakis +4
We consider a Bose-Einstein condensed cloud of atoms which rotate in a toroidal/annular potential. Assuming one-dimensional motion, we evaluate the critical frequencies associated…
