An open harmonic chain: Exact vs global and local reduced dynamics
For a three-oscillator chain with two unequal-temperature baths, the local GKSL master equation is numerically closer to the exact dynamics for weak inter-oscillator coupling, while the global equation wins above a temperature-dependent critical coupling.
