Abstract

Critical observations The Berezinskii–Kosterlitz–Thouless phase transition, occurring in two-dimensional Bose gases, is expected to show an extended range of universal scaling behaviour in thermodynamic quantities. A clear demonstration of this 'critical' behaviour has remained elusive, but now Chen-Lung Hung et al. confirm its existence through in situ density and density-fluctuation measurements of two-dimensional caesium Bose gases at different temperatures and interaction strengths.
