Parametrizations of triaxial deformation and E2 transitions of the wobbling band
Yoshifumi R. Shimizu, Takuya Shoji, Masayuki Matsuzaki
By the very definition the triaxial deformation parameter is related to the expectation values of the K=0 and K=2 components of the intrinsic quadrupole tensor operator. On the…
Tilting instability in negative-γrotating nuclei
Masayuki Matsuzaki
Based on the cranking model and the random phase approximation, we point out that the wobbling excitation on top of the s band in ^{182}Os is stable against angular momentum tiltin…
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…
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…
