We analyze different decoherence processes in a system coupled to a bath. Apart from the well known standard dephasing mechanism which is temperature dependent an alternative mechanism is presented, the spin-swap dephasing which does not need initial bath activation and is temperature independent. We show that for dipolar interaction the separation of time scales between system and bath can not produce pure dephasing, the process being accompained by dissipation. Activated and non activated…

TLDR
The performance characteristics of a heat rectifier and a heat pump are studied in a non Markovian framework and the combined system is studied in various system-bath coupling strengths.
