Quantum Phases of Attractive Matter Waves in a Toroidal Trap / A. Parola, L. Salasnich, R. Rota, L. Reatto. - In: PHYSICAL REVIEW A. - ISSN 1050-2947. - 72:6(2005), p. 063612.063612.
Abstract:
Investigating the quantum phase transition in a ring from a uniform attractive Bose-Einstein condensate to a localized bright soliton we find that the soliton undergoes transverse collapse at a critical interaction strength, which depends on the ring dimensions. In addition, we predict the existence of other soliton configurations with many peaks, showing that they have a limited stability domain. Finally, we show that the phase diagram displays several new features when the toroidal trap is set in rotation.
