Dark solitons of the Gross-Neveu model
arXiv:2111.00836 · doi:10.1093/ptep/ptab165
Abstract
We present N-soliton solutions for the classical (1+1)-dimensional Gross-Neveu model which satisfy non-zero boundary conditions. These solutions are obtained by direct method using some properties of the soliton matrices that appear in the framework of the Cauchy matrix approach.
