Chiral Anomaly and Spin Gap in One-Dimensional Interacting Fermions
Semiclassical approach has been developed for the one-dimensional interacting fermion systems. Starting from the incommensurate spin density wave (SDW) mean field state for the repulsive Hubbard model in 1D, the nonAbelian bosonized Lagrangian describing the spin-charge separation is obtained. The Berry phase term is derived from the chiral anomaly, and we obtain the massless Tomonaga-Luttinger...
متن کاملAdsorption and diffusion in a one-dimensional potential well.
We investigate the adsorption and diffusion of colloidal particles at an interface containing a one-dimensional potential well. It is observed how the adsorption kinetics onto the wall is altered with time, and one observes the formation of a particle chain. We find that the time it takes for a bead to penetrate into the chain depends strongly on the particle density, and beyond a critical valu...
متن کاملOne-dimensional anyons with competing δ-function and derivative δ-function potentials
We propose an exactly solvable model of one-dimensional anyons with competing δ-function and derivative δ-function interaction potentials. The Bethe ansatz equations are derived in terms of the N -particle sector for the quantum anyonic field model of the generalized derivative nonlinear Schrödinger equation. This more general anyon model exhibits richer physics than that of the recently studie...
متن کاملD-anyons: one-dimensional anyons with competing δ-function and derivative δ-function potentials
We propose an exactly solvable model of anyons confined to one dimension with competing δ-function and derivative δ-function interaction potentials. The Bethe ansatz equations are derived in terms of the N -particle sector for the quantum anyonic field model of the generalized derivative nonlinear Schrödinger equation. This more general anyon model exhibits richer physics than that of the recen...
متن کاملOne-dimensional SU(3) bosons with δ-function interaction
Abstract In this paper, we solve one-dimensional SU(3) bosons with repulsive δ-function interaction using the Bethe ansatz method. The features of the ground and low-lying excited states are studied by both numerical and analytical methods. We show that the ground state is a SU(3) colour ferromagnetic state. The configurations of quantum numbers for the ground state are given explicitly. For a ...
