Exact Solution of Double δ Function Bose Gas through an Interacting Anyon Gas
Abstract
A 1D Bose gas interacting through δ,δ' and double δ function potentials is shown to be equivalent to a δ anyon gas, allowing an exact Bethe ansatz solution. In the noninteracting limit, it describes an ideal gas with generalized exclusion statistics and solves some recent controversies.
