标题： Radiation from a uniformly accelerating harmonic oscillator

摘要： 我们考虑一个均匀加速的谐振子的辐射，其与标量场的最小耦合突然变化。 量子算符的精确时间演化是用受迫谐振子的经典解来表示的。 在耦合常数跳变之后，振子迅速吸收能量，然后随后缓慢地发射能量。 在这里，吸收的能量与加速度无关，并且与场的高动量截断的对数成正比。 发射的能量依赖于加速度，并且也与截断的对数成正比。 特别是，如果耦合与探测器的自然频率（$e^2/(4m) \sim \omega_0$）相当，大量的能量会从振子中辐射出去。 显示英文摘要

摘要： We consider a radiation from a uniformly accelerating harmonic oscillator whose minimal coupling to the scalar field changes suddenly. The exact time evolutions of the quantum operators are given in terms of a classical solution of a forced harmonic oscillator. After the jumping of the coupling constant there occurs a fast absorption of energy into the oscillator, and then a slow emission follows. Here the absorbed energy is independent of the acceleration and proportional to the log of a high momentum cutoff of the field. The emitted energy depends on the acceleration and also proportional to the log of the cutoff. Especially, if the coupling is comparable to the natural frequency of the detector ($e^2/(4m) \sim \omega_0$) enormous energies are radiated away from the oscillator.
