Influence of geometry variations on the gravitational focusing of timelike geodesic congruences
Masafumi Seriu
We derive a set of equations describing the linear response of the convergence properties of a geodesic congruence to arbitrary geometry variations. It is a combination of equation…
Asymptotic principal values and regularization methods for correlation functions with reflective boundary conditions
Masafumi Seriu
We introduce a concept of asymptotic principal values which enables us to handle rigorously singular integrals of higher-order poles encountered in the computation of various quant…
Smearing effect due to the spread of a probe-particle on the Brownian motion near a perfectly reflecting boundary
Masafumi Seriu, Chun-Hsien Wu
Quantum fluctuations of electromagnetic vacuum are investigated in a half-space bounded by a perfectly reflecting plate by introducing a probe described by a charged wave-packet di…
Switching effect upon the quantum Brownian motion near a reflecting boundary
Masafumi Seriu, Chun-Hsien Wu
The quantum Brownian motion of a charged particle in the electromagnetic vacuum fluctuations is investigated near a perfectly reflecting flat boundary, taking into account the smoo…
Dynamical Evolution of a Cylindrical Shell with Rotational Pressure
Masafumi Seriu
We prepare a general framework for analyzing the dynamics of a cylindrical shell in the spacetime with cylindrical symmetry. Based on the framework, we investigate a particular mod…
Evolution of the discrepancy between a universe and its model
Masafumi Seriu
We study a fundamental issue in cosmology: Whether we can rely on a cosmological model to understand the real history of the Universe. This fundamental, still unresolved issue is o…
