Chiral phase transition and color superconductivity in an extended NJL model with higher-order multi-quark interactions
K. Kashiwa, H. Kouno, T. Sakaguchi +2
The chiral phase transition and color superconductivity in an extended NJL model with eight-quark interactions are studied. The scalar-type nonlinear term hastens the chiral phase…
Wobbling motion in triaxial superdeformed nuclei
Masayuki Matsuzaki, Yoshifumi R. Shimizu, Kenichi Matsuyanagi
We discuss some characteristic features of the wobbling motion excited on the triaxial superdeformed Lu nucleus. We show how these features are connected to the moments of inertia…
Chiral phase transition in an extended NJL model with higher-order multi-quark interactions
Kouji Kashiwa, Hiroaki Kouno, Tomohiko Sakaguchi +2
The chiral phase transition is studied in an extended Nambu--Jona-Lasinio model with eight-quark interactions. Equations for scalar and vector quark densities, derived in the mean…
Meson loop effect on high density chiral phase transition
Tomohiko Sakaguchi, Kouji Kashiwa, Masayuki Matsuzaki +2
We test the stability of the mean-field solution in the Nambu--Jona-Lasinio model. For stable solutions with respect to both the σand πdirections, we investigate effects of the mes…
Liquid-gas instability and superfluidity in nuclear matter
Masayuki Matsuzaki
We study effects of the medium polarization on superfluidity in symmetric nuclear matter in a relativistic formalism. An effect of the liquid-gas instability is emphasized. We exam…
