Abstract
We find the general solution to the time-dependent Hartree-Fock problem for scattering solutions of the Gross–Neveu models, with both discrete () and continuous () chiral symmetry. We find new multibreather solutions both for the model, generalizing the Dashen–Hasslacher–Neveu breather solution, and also new twisted breathers for the model. These solutions satisfy the full time-dependent Hartree-Fock consistency conditions, and only in the special cases of kink scattering do these conditions reduce to the integrable Sinh–Gordon equation. We also show that all baryons and breathers are composed of constituent twisted kinks of the model. Our solution depends crucially on a general class of transparent, time-dependent Dirac potentials found recently by algebraic methods.
