Bose-Einstein-Young condensates
Abstract
Description
We demonstrate a possibility to create a new state of ultracold atoms which we call a Bose-Einstein-Young condensate. Atoms are supposed to be in different hyperfine state of the same isotope. The wave function of such a state, although totally symmetric with respect to simultaneous permutation of co-ordinates and spins of any pair of atoms, has more complicated structure than a simple product of totally symmetric co-ordinate and spin parts. Its properties with respect to permutations of only co-ordinates or only spins are characterized by a particular Young diagram, a symbol denoting an irreducible representation of the permutation group.
