Abstract: | We derive quantum diffusion equations with transport coefficients explicitly depending on time from generalized non-Markovian
Langevin equations and obtain generalized fluctuation-dissipation relations. We substantiate the axiomatic Lindblad approach
in the microscopic model. For non-Markovian dynamics, we find sets of diffusion coefficients that ensure the purity of states
at any instant.
