ab: Summary: Interactions between a quantum system and its environment at low
    temperatures can lead to apparent violations of thermal laws for the
    system. The source of these violations is the coupling between the
    system and the environment, which prevents the system from entering
    into a thermal state, a state of Gibb’s form. On the other hand, for
    two-state systems, we show that one can define an effective
    temperature, placing the system into a ‘pseudo-thermal’ state where
    effective thermal laws can be applied. We then numerically explore
    these assertions for an $n$-state environment inspired by the
    spin-boson environment.
