Entropy production in open quantum systems: exactly solvable qubit models

Entropy production in open quantum systems: exactly solvable qubit models

We present analytical results for the time-dependent information entropy in exactly solvable two-state (qubit) models. The first model describes dephasing (decoherence) in a qubit coupled to a bath of harmonic oscillators. The entropy production for this model in the regimes of "complete"...
