Microscopic theory of energy dissipation and decoherence in solid-state systems: A reformulation of the conventional Markov limit
Michele Pepe, David Taj, Rita Claudia Iotti +1
We present and discuss a general density-matrix description of energy-dissipation and decoherence phenomena in open quantum systems, able to overcome the intrinsic limitations of t…

Dissipation and Decoherence in Nanodevices: a Generalized Fermi's Golden Rule
David Taj, Rita Claudia Iotti, Fausto Rossi
We shall revisit the conventional adiabatic or Markov approximation, which --contrary to the semiclassical case-- does not preserve the positive-definite character of the correspon…
