Phase structure of the massive chiral Gross-Neveu model from Hartree-Fock
Christian Boehmer, Ulf Fritsch, Sebastian Kraus +1
The phase diagram of the massive chiral Gross-Neveu model (the massive Nambu-Jona-Lasinio model in 1+1 dimensions) is constructed. In the large N limit, the Hartree-Fock approach c…
Baryons in the large N limit of the massive two-dimensional Nambu-Jona-Lasinio model
Christian Boehmer, Felix Karbstein, Michael Thies
Baryons in the massive Nambu-Jona-Lasinio model in 1+1 dimensions (the massive chiral Gross-Neveu model) are studied in the limit of an infinite number of flavors. The baryon mass…
Tricritical behavior of the massive chiral Gross-Neveu model
Christian Boehmer, Michael Thies, Konrad Urlichs
The phase diagram of the massive chiral Gross-Neveu model (the 1+1-dimensional Nambu-Jona-Lasinio model at large N) is investigated in the vicinity of the tricritical point. Using…
