Exploring Flatland with Quantum Gases
Copyright: Prof. Dr. Jean Dalibard
In a 2D world, most transitions towards ordered states of matter like crystals or magnets would not occur because of the increased role of fluctuations. However, non-conventional topological transitions can still occur, as understood by Kosterlitz and Thouless.
In this talk I will present some important features of Flatland physics explored with cold atomic gases, such as the transition to a superfluid phase and the emergence of quasi long-range order. I will also connect the physics of these atomic systems with other prominent topological properties of matter, such as quantum-Hall type phenomena.
