Abstract

Dimensionality can drastically affect order phenomena. We study the Berezinskii-Kosterlitz-Thouless phase transition in a two dimensional ultracold Bose gas. This transition to superfluidity without true long-range order replaces Bose-Einstein condensation known from three dimensional systems. Article not available.
