Short summary
This work provides some clarifications on the long-known Redfield theory of spin relaxation, which considers a small system coupled to a large ensemble of particles in thermodynamic equilibrium. The derivation is rewritten so as to emphasize the usual assumptions and their consequences. In particular, the respective roles of the detailed balance balance assumption and the non-commutativity of the spin–bath coupling are discussed.
