A Two-Dimensional Model with Chiral Condensates and Cooper Pairs Having QCD-like Phase Structure
Alan Chodos, Hisakazu Minakata, Fred Cooper +2
We describe how a generalization of the original Gross-Neveu model from U(N) to O(N) flavor symmetry leads to the appearance of a pairing condensate at high density, in agreement w…
Competing Condensates in Two Dimensions
Alan Chodos, Fred Cooper, Hisakazu Minakata
We generalize our previous 2-dimensional model in which a pairing condensate psi-psi was generated at large N. In the present case, we allow for both psi-psi and a chiral condensat…
Cosmological Neutrino Condensates
D. G. Caldi, Alan Chodos
We investigate the possibility that neutrinos form superfluid-type condensates in background cosmological densities. Such condensates could give rise to small neutrino masses and s…
The Gross-Neveu Model with Chemical Potential; An Effective Theory for Solitonic-Metallic Phase Transition in Polyacetylene?
Hisakazu Minakata, Alan Chodos
The Gross-Neveu model with chemical potential is investigated as a low-energy effective theory of polyacetylene. In particular, we focus on the abrupt change in the features of ele…
