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.

研究了描述均匀加速系统的伦德勒空间中的量子场，特别强调了它们在视界附近的行为。计算了标量场、矢量场（电磁场）和张量场（引力场）的传播子，并检验了相应的粒子交换势。阐明了它们的虚部与伦德勒空间中已知的Unruh效应之间的关系，讨论了视界附近物质的稳定性。这项研究发表在《物理学》杂志上。在标量场的情况下，也研究了它们的热力学性质。本征模的能谱具有伦德勒空间的简并特征，热力学函数具有空间维数2的简并特征。关于这项工作的论文正在准备中。
