Universality in Dynamical Formation of Entanglement for Quantum Chaos
Hiroto Kubotani, Mikito Toda, Satoshi Adachi
Dynamical formation of entanglement is studied for quantum chaotic bi-particle systems. We find that statistical properties of the Schmidt eigenvalues for strong chaos are well des…
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…
de Broglie-Bohm Interpretatin for Analytic Solutions of The Wheeler-DeWitt Equation in Spherically Symmetric Space-time
Masakatsu Kenmoku, Hiroto Kubotani, Eiichi Takasugi +1
We discuss the implications of a wave function for quantum gravity, which involves nothing but 3-dimensional geometries as arguments and is invariant under general coordinate trans…
Analytic Solutions of The Wheeler-DeWitt Equation in Spherically Symmetric Space-time
Masakatsu Kenmoku, Hiroto Kubotani, Eiichi Takasugi +1
We study the quantum theory of the Einstein-Maxwell action with a cosmological term in the spherically symmetric space-time, and explored quantum black hole solutions in Reissner-N…
de Broglie-Bohm interpretation for wave function of Reissner-Nordstrom-de Sitter black hole
Masakatsu Kenmoku, Hiroto Kubotani, Eiichi Takasugi +1
We study the canonical quantum theory of the Reissner-Nordstrom-de Sitter black hole(RNdS). We obtain an exact general solution of the Wheeler-DeWitt equation for the spherically s…
