演題:Interacting Anyons in One Dimension: zero-range interactions beyond Bose-Fermi statistics
要旨:Non-relativistic anyons in 1D possess generalized exchange statistics in which the exchange of two identical anyons generates a non-local phase that is governed by the spatial ordering of the particles and the statistical parameter . Working in the continuum, I will discuss the existence of two distinct types of 1D anyons, namely bosonic anyons and fermionic anyons. Later I will introduce a many-body Hamiltonian with additive two-body zero-range interactions that supports bosonic and fermionic anyon eigenstates, which are, for arbitrary interaction strength, related through a generalized bosonic-anyon–fermionic-anyon mapping, an extension of the celebrated Bose-Fermi mapping for zero-range interacting 1D systems. The momentum distributions of bosonic and fermionic anyons are distinct: while both feature and tails, the associated prefactors differ. Our work reveals intricate connections between the generalized exchange statistics, the universal two- and three-body Tan contacts of systems consisting of identical particles, and the emergence of statistics-induced chiral symmetry breaking. I will discuss about possible experimental realization with spin-orbit coupling of two distinguishable bosons.
