Beth-Uhlenbeck equation for the thermodynamics of fluctuations in a generalised 2+1D Gross-Neveu model
Biplab Mahato, David Blaschke, Dietmar Ebert
We study a generalized version of the Gross-Neveu model in 2+1 dimensions. The model is inspired from Graphene, which shows a linear dispersion relation near the Dirac points. The…
Variational path-integral approach to back-reactions of composite mesons in the Nambu-Jona-Lasinio model
D. Blaschke, D. Ebert
For the investigation of back-reactions of composite mesons in the NJL model, a variational path-integral treatment is formulated which yields an effective action $\mathscr{A}_{\rm…
Phase transitions in hexagonal, graphene-like lattice sheets and nanotubes under the influence of external conditions
D. Ebert, K. G. Klimenko, P. B. Kolmakov +1
In this paper we consider a class of (2+1)D schematic models with four-fermion interactions that are effectively used in studying condensed-matter systems with planar crystal struc…
Pseudopotential model for Dirac electrons in graphene with line defects
D. Ebert, V. Ch. Zhukovsky, E. A. Stepanov
We consider electron transport in a planar fermion model containing various types of line defects modelled by --function pseudopotentials with different matrix coefficients. The…
Suppression of superconductivity by inhomogeneous chiral condensation in the NJL model
D. Ebert, T. G. Khunjua, K. G. Klimenko +1
We investigate the possibility of spatially inhomogeneous chiral and Cooper, or superconducting, pairing in the (1+1)-dimensional model by Chodos et al [ Phys. Rev. D61, 045011 (20…
Finite-size effects in pion condensation phenomena of dense baryonic matter in the NJL model
D. Ebert, T. G. Khunjua, K. G. Klimenko +1
The properties of two-flavored massless Nambu-Jona-Lasinio model in (1+1)-dimensional spacetime with compactified space coordinate are investigated in the presence…
