Few-Body Physics in Quantum Gases
Few-body effects play an important role for the understanding of ultracold quantum gases. We make use of an effective field theory approach to investigate various aspects of universal few-body physics close to a Feshbach resonance. That is the regime where the scattering length is large compared to all other length scales of the system and thus determines the observables. It is also the regime ...
متن کاملMany-Body Physics: Unfinished Revolution
The study of many-body physics has provided a scientific playground of surprise and continuing revolution over the past half century. The serendipitous discovery of new states and properties of matter, phenomena such as superfluidity, the Meissner, the Kondo and the fractional quantum hall effects, have driven the development of new conceptual frameworks for our understanding about collective b...
متن کاملFew-body physics in effective field theory
Effective Field Theory (EFT) provides a powerful framework that exploits a separation of scales in physical systems to perform systematically improvable, model-independent calculations. Particularly interesting are few-body systems with short-range interactions and large two-body scattering length. Such systems display remarkable universal features. In systems with more than two particles, a th...
متن کاملUltracold halo dimers and few-body physics
Ultracold dimers in s-wave states are in the quantum halo regime1, if their binding energy is much smaller than a typical energy set by the long-range van der Waals interaction. In this regime, the scattering length is very large and details of the interatomic interaction become irrelevant. Studying the interactions of halo dimers provides experimental access to universal phenomena in few-body ...
