作为谱几何的真空能量

Vacuum Energy as Spectral Geometry

Stephen A. Fulling

摘要:

量子真空能量(卡西米尔能量)是回顾了数学观众作为一个主题,在谱理论。然后用闭经典轨道和周期轨道精确求解了某些一维系统。证明了局域谱密度、能量密度、全局本征值密度和总能量之间的关系。这一材料提供了用半经典近似和其他方法处理高维系统(自伴二阶偏微分算子)的背景和动机。

英文摘要:

Quantum vacuum energy (Casimir energy) is reviewed for a mathematical audience as a topic in spectral theory. Then some one-dimensional systems are solved exactly, in terms of closed classical paths and periodic orbits. The relations among local spectral densities, energy densities, global eigenvalue densities, and total energies are demonstrated. This material provides background and motivation for the treatment of higher-dimensional systems (self-adjoint second-order partial differential operators) by semiclassical approximation and other methods.
