Density Renormalization Group for Classical Liquids
Satoshi Iso, Kiyoharu Kawana
We study response of liquid to a scale transformation, which generates a change of the liquid density, and obtain a set of differential equations for correlation functions. The set…
Amplification of gravitational motion via Quantum weak measurement
Kiyoharu Kawana, Daiki Ueda
We investigate a new experimental possibility of measuring the Newtonian gravitational constant by using the weak measurement. Amplification via weak measurement is one of the…
Hillclimbing saddle point inflation
Kiyoharu Kawana, Katsuta Sakai
Recently a new inflationary scenario was proposed in arXiv:1703.09020 which can be applicable to an inflaton having multiple vacua. In this letter, we consider a more general situa…
RG-improvement of the effective action with multiple mass scales
Satoshi Iso, Kiyoharu Kawana
Improving the effective action by the renormalization group (RG) with several mass scales is an important problem in quantum field theories. A method based on the decoupling theore…
