| Research Abstract |
Quantum fields in Rindler space, which describes uniformly accelerated systems, are studied, with particular emphasis on their behaviors near the horizon. Propagators of scalar, vector (electromagnetic) and tensor (gravitational) fields are calculated and corresponding particle exchange potentials are examined. The relation between their imaginary parts and the Unruh effect known in Rindler space is clarified and the stability of matter near the horizon is discussed. This work has been published in Phys. Rev. D In the case of scalar fields, their thermodynamic properties are also studied. The energy spectra of the eigenmodes have degeneracies characteristic of Rindler space and the thermodynamic functions are found to have features of those for spatial dimension 2. A paper is now in preparation on this work.
