Effect of Soft Modes on the Shear Viscosity of Quark Matter
Takahiko Fukutome, Masaharu Iwasaki
We calculate shear viscosity of the quark matter at finite temperature and density. If we assume that the quark interacts with the soft mode, which is a collective mode of quark-an…
Shear viscosity of the quark matter
Masaharu Iwasaki, Hiromasa Ohnishi, Takahiko Fukutome
We discuss shear viscosity of the quark matter by using Kubo formula. The shear viscosity is calculated in the framework of the quasi-particle RPA for the Nambu-Jona-Lasinio model.…
Shear viscosity and spectral function of the quark matter
Masaharu Iwasaki, Hiromasa Ohnishi, Takahiko Fukutome
We discuss the shear viscosity of the quark matter by using the Kubo-Mori formula. It is found that the shear viscosity is expressed in terms of the quark spectral function. If the…
First order phase transition in the quark matter
Masaharu Iwasaki
We investigate chiral phase transition of the first order in the quark matter. Using the Nambu-Jona-Lasinio model, an equation of state of the quark matter which is similar to the…
Tetraquark particle in the string model
Masaharu Iwasaki, Takahiko Fukutome
We discuss possibility of the existence of tetraquark states made of four quarks in the string (flux tube) model. The new particle is composed of a diquark and an anti-diquark whic…
Latent heat in the chiral phase transition
Masaharu Iwasaki, Hiyoshi Kiuchi
The chiral phase transition at finite temperature and density is discussed in the framework of the QCD-like gauge field theory. The thermodynamical potential is investigated using…
