有色真空中自发发射动力学的计算
Computation of spontaneous emission dynamics in colored vacua
摘要：
提出了一种计算有色真空中自发发射动力学的有效时域数值格式。从第一性原理出发，我们将缀饰二能级量子发射体的幺正演化映射到自相互作用条件下复谐振子的电磁辐射问题。这后一个干扰场系统可以有效地集成使用有限差分时域方法，而不需要计算周围环境的光子本征模。与以前的调查相比，我们的计算框架提供了一个统一的数值处理弱耦合和强耦合制度一样。我们通过考虑几个不同的例子来说明我们的计划的多功能性。
英文摘要：
We present an efficient time domain numerical scheme for computing spontaneous emission dynamics in colored vacua. Starting from first principles, we map the unitary evolution of a dressed two-level quantum emitter onto the problem of electromagnetic radiation from a complex harmonic oscillator under self-interaction conditions. This latter oscillator-field system can be efficiently integrated by using finite difference time domain method without the need for calculating the photonic eigenmodes of the surrounding environment. In contrast to earlier investigations, our computational framework provides a unified numerical treatment for both weak and strong coupling regimes alike. We illustrate the versatility of our scheme by considering several different examples.
