| Research Abstract |
We have attempted to construct a non-perturbative formula for description of transport phenomena in strongly correlated systems, such as finite-temperature and -density QCD and many-body systems of cold atoms around the unitary limit. Transport coefficients, which characterize non-equilibrium state at low energy and long wave-length limit of the systems, are evaluated by the Functional renormalization group method, in which we can start from microscopic Lagrangian and integrate out high energy modes to get low energy effective theories. Also, as a complementary method, we have employed effective field theories on basis of symmetries and their spontaneous breaking.
In formulation for spontaneous symmetry breaking phases, we are left with some problems, e.g., to see if the renormalization group method automatically produces effective degrees of freedom at low energies.
