On the Discretization Error of the Discrete Generalized Quantum Master Equation
Ruojing Peng, Lachlan P. Lindoy, Joonho Lee
The transfer tensor method (TTM) [Cerrillo and Cao, Phys. Rev. Lett. 2014, 112, 110401] can be considered a discrete-time formulation of the Nakajima-Zwanzig quantum master equatio…
