\omega(r,t')dt'}dr$
- Coherent - when ω is not a function of r (There are no interesting dynamics)
- Stationary - when ω is not a function of time (the system can be refucus by a π pulse for any time)
- Incoherent - stationary and not coherent, explicitly $\omega$ is a function of r (interesting question is the distribution of ω(r)
- Decoherent - when ω is a function of time and r, and the t dependence is stochastic/Marchovian (interesting dynamics: distribution of ω(r), spectral density of ω(r)
- Periodic - ω is a simple function of time (interesting dynamics: distribution of ω(r) at the characteristic frequency)
