Transport coefficient
text:
A transport coefficient γ measures how rapidly a perturbed system returns to equilibrium. The transport coefficients occur in transport phenomenon with transport laws where: Transport coefficients can be expressed via a Green–Kubo relation: where A is an observable occurring in a perturbed Hamiltonian, ⟨ ⋅ ⟩ is an ensemble average and the dot above the A denotes the time derivative.
For times t that are greater than the correlation time of the fluctuations of the observable the transport coeffic
