Analytical solution of the Gross-Neveu model at finite density
نویسنده
چکیده
Recent numerical calculations have shown that the ground state of the Gross-Neveu model at finite density is a crystal. Guided by these results, we can now present the analytical solution to this problem in terms of elliptic functions. The scalar potential is the superpotential of the nonrelativistic Lamé Hamiltonian. This model can also serve as analytically solvable toy model for a relativistic superconductor in the Larkin-Ovchinnikov-Fulde-Ferrell phase.

Variational solution of the Gross - Neveu model at finite temperature in the large N limit
Variational solution of the Gross-Neveu model at finite temperature in the large N limit. Abstract We use an improved nonperturbative variational method to investigate the phase transition of the Gross-Neveu model. It is shown that the variational procedure can be generalized to the finite temperature case. The large N result for the phase transition is correctly reproduced.
متن کاملThe Gross-Neveu Model with Chemical Potential; An Effective Theory for Solitonic-Metallic Phase Transition in Polyacetylene?
The Gross-Neveu model with chemical potential is investigated as a lowenergy effective theory of polyacetylene. In particular, we focus on the abrupt change in the features of electric conductivity such as sharp rise in the Pauli paramagnetism at dopant concentration of about 6%. We will try to explain it by the finite density phase transition in the Gross-Neveu model. The thermodynamic Bethe a...
متن کاملPhase Diagram of Gross-Neveu Model at Finite Temperature, Density and Constant Curvature
We discuss a phase structure of chiral symmetry breaking in the Gross-Neveu model at finite temperature, density and constant curvature. The effective potential is evaluated in the leading order of the 1/N -expansion and in a weak curvature approximation. The third order critical line is found on the critical surface in the parameter space of temperature, chemical potential and constant curvatu...
متن کاملEmergence of Skyrme crystal in Gross-Neveu and ’t Hooft models at finite density
We study two-dimensional, large N field theoretic models (Gross-Neveu model, ’t Hooft model) at finite baryon density near the chiral limit. The same mechanism which leads to massless baryons in these models induces a breakdown of translational invariance at any finite density. In the chiral limit baryonic matter is characterized by a spatially varying chiral angle with a wave number depending ...
متن کاملLee-Yang edge singularity in the three-dimensional Gross-Neveu model at finite temperature
We discuss the relevance of the Lee-Yang edge singularity to the finite-temperature Z2-symmetry restoration transition of the Gross-Neveu model in three dimensions. We present an explicit result for its large-N free-energy density in terms of ζ(3) and the absolute maximum of Clausen’s function. The Gross-Neveu model in d = 3 dimensions provides a remarkable example of a second order temperature...
