Four-fermion interaction models are often used as simplified models of interacting fermion fields with the chiral symmetry. The chiral symmetry is dynamically broken for a larger four-fermion coupling. It is expected that the broken symmetry is restored under extreme conditions. In this paper, the finite size effect on the chiral symmetry breaking is investigated in the four-fermion interaction model. We consider the model on a flat spacetime with a compactified spatial coordinate, M D − 1 ⊗ S… Expand

D mesons as a probe of Casimir effect for chiral symmetry breaking
We propose $D$ mesons as probes to investigate finite-volume effects for chiral symmetry breaking at zero and finite temperatures. By using the $2+1$-flavor linear sigma model with constituent lightExpand
Charged Pion Condensation in Dense Quark Matter: Nambu-Jona-Lasinio Model Study
TLDR
It is shown that in real physical systems there could be conditions promoting the appearance of charged PC phenomenon in dense quark matter; specifically, if one takes into consideration the fact that system can have finite size, then a dense charged PC phase can be realized there. Expand
