Shear viscosity of classical Yang-Mills field

Hidefumi Matsuda, Teiji Kunihiro, Berndt Müller +2

We investigate the shear viscosity of the classical Yang-Mills (CYM) field on a lattice by using the Green-Kubo formula, where the shear viscosity is calculated from the time-c…

Probing the BSM physics with CMB precision cosmology: an application to supersymmetry

Ioannis Dalianis, Yuki Watanabe

The cosmic history before the BBN is highly determined by the physics that operates beyond the Standard Model (BSM) of particle physics and it is poorly constrained observationally…

Entropy production and isotropization in Yang-Mills theory with use of quantum distribution function

Hidekazu Tsukiji, Teiji Kunihiro, Akira Ohnishi +1

We investigate thermalization process in relativistic heavy ion collisions in terms of the Husimi-Wehrl (HW) entropy defined with the Husimi function, a quantum distribution functi…

Entropy production from chaoticity in Yang-Mills field theory with use of the Husimi function

Hidekazu Tsukiji, Hideaki Iida, Teiji Kunihiro +2

We investigate possible entropy production in Yang-Mills (YM) field theory by using a quantum distribution function called Husimi function for YM field, which…

Study of entropy production in Yang-Mills theory with use of Husimi function

Hidekazu Tsukiji, Hideaki Iida, Teiji Kunihiro +2

Understanding the thermalization process in a pure quantum system is a challenge in theoretical physics. In this work, we explore possible thermalization mechanism in Yang-Mills(YM…

Entropy production in quantum Yang-Mills mechanics in semi-classical approximation

Hidekazu Tsukiji, Hideaki Iida, Teiji Kunihiro +2

We discuss thermalization of isolated quantum systems by using the Husimi-Wehrl entropy evaluated in the semiclassical treatment. The Husimi-Wehrl entropy is the Wehrl entropy obta…

Entropy production in classical Yang-Mills theory from Glasma initial conditions

Hideaki Iida, Teiji Kunihiro, Berndt Mueller +3

We study the thermalization process in classical Yang-Mills (CYM) field theory starting from noisy glasma-like initial conditions by investigating the initial-value sensitivity of…

Tetraquark and Pentaquark Systems in Lattice QCD

F. Okiharu, T. Doi, H. Ichie +5

Motivated by the recent experimental discoveries of multi-quark candidates, e.g., the , we study multi-quark systems in lattice QCD. First, we perform accurate mass meas…

Chaotic dynamics in preheating after inflation

Yoshida Jin, Shinji Tsujikawa

We study chaotic dynamics in preheating after inflation in which an inflaton is coupled to another scalar field through an interaction . We first estimate t…
