  abstract = {In this chapter we review the recent advances in experimental investigation and theoretical understanding of Berezinskii–Kosterlitz–Thouless (BKT) physics in ultracold trapped atomic gases. We explain how to produce quasi two-dimensional (2D) samples by freezing out one degree of freedom with laser beams, and we detail the modeling of atomic interactions in this constrained geometry. We discuss some remarkable properties of the equation of state of dilute 2D Bose gases, such as its scale invariance. We also comment on the “competition” between the superfluid, BKT-driven phase transition in a homogenous 2D fluid of bosons, and the more conventional Bose–Einstein condensation that is expected for an ideal 2D Bose gas confined in a harmonic potential. We present some experimental techniques that allow one to measure the equation of state of the gas, monitor the occurrence of a BKT-driven phase transition, and observe thermally activated quantized vortices, which constitute the microscopic building block of the BKT mechanism…},
