An experimental <atomic physicist> who coauthored a test of the <Berezinskii–Kosterlitz–Thouless transition> in trapped <ultracold gases>. Interference measurements examined how coherence changes with <temperature>, giving a laboratory probe of ordering that differs from conventional three-dimensional <Bose-Einstein condensation>.<Berezinskii-Kosterlitz-Thouless Crossover in a Trapped Atomic Gas by Zoran Hadzibabic and others>[Coherence measurements and low-dimensional crossover]{ref}
