This article details theoretical advancements in two-dimensional quantum gases, specifically explaining superfluidity mechanisms like the Berezinskii-Kosterlitz-Thouless transition and scaling symmetry. The work provides essential educational resources for understanding exotic states of matter in ultracold atomic systems, which are foundational to future quantum technologies.
Lpl Team Details Two-Dimensional Gas Superfluidity Mechanisms

Two-dimensional quantum Bose gases now have their superfluidity explained via the Berezinskii, Kosterlitz, Thouless mechanism alongside detailed analysis of scaling symmetry. Previously, comprehensive courses addressing this specific interplay were not readily available to students at the São Paulo ICTP-SAIFR School. These lectures consolidate theoretical foundations for exploring exotic states of matter and potential new technologies.
Theoretical foundations for understanding two-dimensional quantum gases are detailed in a series of three lectures delivered at the São Paulo ICTP-SAIFR IVth School on Light and Cold Atoms. This course enables thorough description of phenomena including Bose-Einstein condensation, superfluidity, scaling symmetry, and vortex lattice behaviour in rotating systems. A detailed educational resource on two-dimensional quantum gases has been developed, explaining complex behaviours like superfluidity through mechanisms involving phase fluctuations and scaling symmetry.
