Fermion-Boson Duality of One-dimensional Quantum Particles with Generalized Contact Interaction
Abstract
For a system of spinless one-dimensional fermions, the non-vanishing short-range limit of two-body interaction is shown to induce the wave-function discontinuity. We prove the equivalence of this fermionic system and the bosonic particle system with two-body δ-function interaction with the reversed role of strong and weak couplings. KEYWORDS: one-dimensional system, ε-interaction, solvable many-body problem, exact bosonization
