Bose-Einstein Condensation in Geometrically Deformed Tubes

TL;DR

This paper demonstrates that Bose-Einstein condensates can be achieved in quasi-one-dimensional systems through geometric deformation of the confining tube, such as bending.

Contribution

It introduces a novel method of inducing Bose-Einstein condensation via geometrical deformation rather than traditional temperature or interaction controls.

Findings

Condensation can be triggered by bending the tube.

Geometrical deformation affects the quantum states in the system.

Purely geometric methods can induce quantum phase transitions.

Abstract

We show that Bose-Einstein condensate can be created in quasi-one-dimensional systems in a purely geometrical way, namely by bending or other suitable deformation of a tube.
