Local Master Equation for Small Temperatures
Abstract: We present a local Master equation for open system dynamics in two forms: Markovian and non-Markovian. Both have a wider range of validity than the Lindblad equation investigated by Davies.For low temperatures, they do not require coupling to be exponentially weak in the system size. If the state remains a low bond dimension Matrix Product State throughout the evolution, the local equation can be simulated in time polynomial in system size. arXiv:1611.04188
We also investigate protocols like that of a D-Wave machine with the local master equation in the upcoming paper "Slow driving of disordered systems".
