Outline of Final Research Achievements

Our collaboration is titled as Unified understandings of space-time structure and non-equilibrium physics. The major achievements of our collaboration are the followings. de Sitter space-time produces its characteristic super-horizon quantum fluctuation.We have pointed out that it could make fundamental couplings time dependent. We have make it clear that this effect is a consequence of the local Lorentz invariance of the general covariant theory. We have also pointed out that this quantum effect with ultra violet infrared mixing, could lead to time dependence of Dark energy and discussed its possible experimental confirmation.
