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…
Larkin-Ovchinnikov-Fulde-Ferrell state in two-color quark matter
Kenji Fukushima, Kei Iida
We explore the phase structure of two-color and two-flavor QCD in the space of the quark chemical potential μ_q and the isospin chemical potential μ_I. Using a mean-field model we…
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.…
Amplification of Quantum Meson Modes in the Late Time of the Chiral Phase Transition
K. Watanabe, Y. Tsue
We investigate the time evolution of the quantum meson modes in the late time of chiral phase transition. In particular, it is shown that there exists a possible solution to the eq…
Landau Potential Study of the Chiral Phase Transition in a QCD-Like Theory
Y. Tsue, H. Fujii, Y. Hashimoto
We investigate the chiral phase transition of a QCD-like theory, based the shape change of the effective potential near the critical point. The potential is constructed with the au…
The distribution of localization centers in some discrete random systems
Fumihiko Nakano
As a supplement of our previous work, we consider the localized region of the random Schroedinger operators on and study the point process composed of their eigenv…
