Abstract

Few years ago it was suggested by S. Tan that the properties of cold and dilute quantum gases depend on a new characteristic quantity, the ``contact''. The ``contact'' describes the probability of two particles coming close to each other, i.e. it is a measure of the number of close particle pairs in the system. Utilizing this concept, a series of theorems, already verified experimentally, predicts the macroscopic properties of the system. In my talk I will present Tan’s  ``contact'' and its generalization to nuclear systems, introducing the various nuclear contacts, and their applications.
