Universal Non-Gaussian Velocity Distribution in Violent Gravitational Processes
O. Iguchi, Y. Sota, T. Tatekawa +2
We study the velocity distribution in spherical collapses and cluster-pair collisions by use of N-body simulations. Reflecting the violent gravitational processes, the velocity dis…
Bose Einstein Condensation as Dark Energy and Dark Matter
Masako Nishiyama, Masa-aki Morita, Masahiro Morikawa
We study a cosmological model in which the boson dark matter gradually condensates into dark energy. Negative pressure associated with the condensate yields the accelerated expansi…
Linear Temperature-Mass relation and Local virial relation: Two hypotheses for self-gravitating systems
Y. Sota, O. Iguchi, M. Morikawa +1
We propose two hypotheses which characterize the quasi-equilibrium state that realizes after a cold collapse of self-gravitating system. The first hypothesis is the linear temperat…
Complete Resolution of the Quantum Zeno Paradox for Outside Observers
M. Hotta, M. Morikawa
The quantum Zeno paradox is fully resolved for purely indirect and incomplete measurements performed by the detectors outside the system. If the outside detectors are prepared to o…
