Abstract: We derive exact solutions for a one-dimensional Gross–Pitaevskii system with Neumann boundary conditions using Jacobi elliptic functions. Additionally, we investigate the classical linearized eigenvalue problem for this system, providing three exact special eigenpairs and determining… read more here.

Abstract: Using a nonperturbative approach based on the Cornwall–Jackiw–Tomboulis (CJT) effective action [Formula: see text] for composite operators, the phase structure of the simplest massless [Formula: see text]-dimensional Gross–Neveu model is investigated. We have calculated [Formula:… read more here.
