SUMMARY

A structured reservoir in the context of decay and Markov approximation refers to a system where the density of states is not constant, indicating fluctuations in energy levels. The Markov approximation simplifies the analysis by assuming a constant density of states, which is a specific case of the more complex structured reservoir scenario. Understanding these concepts is crucial for accurately modeling systems in statistical mechanics and quantum physics.

PREREQUISITES
  • Understanding of Markov processes and their applications

This is my very first post in this forum, so please correct me, if I'm doing something wrong (if this is not the correct forum for this question or so), but can anyone please tell me what a structured reservoir is when we are working with decay and Markow approximation?

As I understand it, the Markow approximation is the same as saying that the density of states is constant and in the more general case we have a structured reservoir. But what does this mean? Is it just that the density of states is not constant any more and thus is fluctuating?

Thanks

Yes, I believe that's correct.
