Excitation spectrum and critical exponents of a one-dimensional integrable model of fermions with correlated hopping

R. Z. Bariev, A. Klümper, A. Schadschneider +1

We investigate the excitation spectrum of a model of colour fermions with correlated hopping which can be solved by a nested Bethe ansatz. The gapless excitations of particle-h…
