Brief Description

　The subject materials that we have identified so far are not only the hottest current research topics, more important, these are the areas that our community have enough technical know how, expertise, and insights to make major contributions.

To investigate the detailed mechanisms of inflation from non-equilibrium point of view(in particular, stochastic inflation) and compare with CMB data and large scale structures of the universe; the origin of dark matter within or beyond the Standard Model; the physics, properties, and origin of dark energy.

Gravitational energy, gravitational radiation reactions and quasi-normal modes of black holes which affect lots of topics in cosmology will be our main activities.

Canonical quantization of gravity using Ashtekar variables, stochastic gravity using closed-time-path techniques, and quantum to classical transitions will be studied.
