Abstract
We introduce a q-boson system with infinite range interaction which exhibits in the thermodynamic limit a Bose-Einstein condensation. Young tableaux analysis is used to solve the quantum problem of the system and to show that for a particular value of the deformation parameter the system behaves as a Bose gas with hard-core repulsion on a full graph. The method used to solve our system is of general validity and can be applied to other Hamiltonians with infinite range interactions.File in questo prodotto:
