Inhomogeneities in Newtonian Cosmology and its Backreaction to the Evolution of the Universe
Takayuki Tatekawa, Momoko Suda, Kei-ichi Maeda +1
We study an effect of inhomogeneity of density distribution of the Universe. We propose a new Lagrangian perturbation theory with a backreaction effect by inhomogeneity. The inhomo…

Quantum Trajectory in Multi-Dimensional Non-Linear System
Hiroto Kubotani
We discuss quantum dynamics in multi-dimensional non-linear systems. It is well-known that wave functions are localized in a kicked rotor model. However, coupling with other degree…
