Virtual Black Holes in a Third Quantized Formalism
Yoshiaki Ohkuwa, Mir Faizal, Yasuo Ezawa
In this paper, we will analyse virtual black holes using the third quantization formalism. As the virtual black hole model depends critically on the assumption that the quantum flu…
Gravitational waves originated before compactification in Kaluza-Klein theory
T. Ezawa, H. Iwasaki, A. Nakamura +2
We investigate the propagation of multidimensional gravitational waves generated before compactification and observes today as 4-dimensional gravitational waves and gauge fields by…
Correspondence between the first and the second order formalism in the generalized gravity of f(R)-type
Y. Ezawa, H. Iwasaki, Y. Ohkuwa +2
We clarify the correspondence between the first order formalism and the second order formalism in the generalized gravity where the Lagrangian density is given by a function of the…
Coherent state approach to quantum clock in a model where the Hamiltonian is a difference between two harmonic oscillators
Yoshiaki Ohkuwa
In order to study the "problem of time", Rovelli proposed a model of a two harmonic oscillator system where one of the oscillators can be thought of as a 'clock' for the other osci…
