We compute the spectrum of radiation emitted by a generic quantum system interacting with an external classic noise. Our motivation is a wish to understand this phenomenon within the framework of collapse models. However, the computation is general and applies to practically any situation in which a quantum system interacts with a noise. The computation is carried out at a perturbative level. This poses problems as regards the correct way of performing the analysis, as repeatedly discussed in the literature. We will also clarify this issue.

Abstract
We compute the spectrum of radiation emitted by a generic quantum system interacting with an external classic noise. Our motivation is a wish to understand this phenomenon within the framework of collapse models. However, the computation is general and applies to practically any situation in which a quantum system interacts with a noise. The computation is carried out at a perturbative level. This poses problems as regards the correct way of performing the analysis, as repeatedly discussed in the literature. We will also clarify this issue.File in questo prodotto:
