Seminar on Few-Body Systems

On Tuesday 1 March 2016, at 11.00 am in Blokhintsev Hall (4 floor) a seminar “Growth Points of the (Universal) Few-Body Physics” will be held.

Speaker: O.I.Kartavtsev (DLNP, JINR)

Abstract:

Overview of the few-body problems of topical interest is given. Most attention is devoted to the systems, which reveal new and peculiar properties and for which a fast progress is desired. Their modern status is described, unresolved questions are indicated and possible developments are discussed.

An incomplete list of topics includes: appearance of the infinite double-exponential energy spectrum, also known as “super-Efimov” effect; universal four-body resonances in bosonic and fermionic systems; few particles with inverse-square potentials; few-body problem for the sum of the repulsive Coulomb and contact potentials; features of few particles in low and “mixed” dimensions.
