Abstract

In nature, we have many boundaries and interfaces between different kinds of things. Then there are some interesting phenomena related to those interfaces. When we throw a ball into a wall, the ball might go through the wall. Or the reflected ball from the wall might be identical to not the original one but the new one. This new ball would have the information over the wall. In this talk, I would like to introduce you an example of such interesting worlds. One of the goals in this kind of research is to comprehend the transport phenomena in matter. Here I will especially focus on physics of quarks, one of the elementary particles in the standard model of particle physics, based on quantum chromodynamics (QCD), which is the fundamental theory of quarks. My goal in this study is to understand various phenomena happening at the interior of neutron stars and hypothetical quark stars. Throughout the talk, you will see a harmony among particle physics, astrophysics and condensed matter physics.
