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…
Solitary-wave solutions in binary mixtures of Bose-Einstein condensates under periodic boundary conditions
J. Smyrnakis, M. Magiropoulos, G. M. Kavoulakis +1
We derive solitary-wave solutions within the mean-field approximation in quasi-one-dimensional binary mixtures of Bose-Einstein condensates under periodic boundary conditions, for…
Excitation spectrum of a two-component Bose-Einstein condensate in a ring potential
J. Smyrnakis, M. Magiropoulos, A. D. Jackson +1
A mixture of two distinguishable Bose-Einstein condensates confined in a ring potential has numerous interesting properties under rotational and solitary-wave excitation. The lowes…
Solitary waves and yrast states in Bose-Einstein condensed gases of atoms
A. D. Jackson, J. Smyrnakis, M. Magiropoulos +1
Considering a Bose-Einstein condensed gas confined in one dimension with periodic boundary conditions, we demonstrate that, very generally, solitary-wave and rotational excitations…
Solitary waves of Bose-Einstein condensed atoms confined in finite rings
J. Smyrnakis, M. Magiropoulos, G. M. Kavoulakis +1
Motivated by recent progress in trapping Bose-Einstein condensed atoms in toroidal potentials, we examine solitary-wave solutions of the nonlinear Schrödinger equation subject to p…
Solitary waves in mixtures of Bose gases confined in annular traps
J. Smyrnakis, M. Magiropoulos, G. M. Kavoulakis +1
A two-component Bose-Einstein condensate that is confined in a one-dimensional ring potential supports solitary-wave solutions, which we evaluate analytically. The derived solution…
