In a recent study, researchers made a significant observation of the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a 2D dipolar gas of ultracold atoms. This work marks a milestone in understanding how 2D superfluids behave with long-range and anisotropic dipolar interactions. The researchers are an international team of physicists, led by Prof. Jo Gyu-Boong from the Department of Physics at the Hong Kong University of Science and Technology (HKUST).
