This pedagogical review critically re-evaluates the validity regimes of the Lindblad master equation for modeling open quantum systems. By contrasting standard approximations like Born and Markov with refined expectations through case studies, it provides a practical checklist for researchers assessing framework breakdown in driven simulators or many-body contexts. The work is essential for physicists navigating non-equilibrium condensed matter and strongly correlated electron problems where traditional folklore may no longer hold.
Is Lindblad for me?
arXiv:2506.22436v3 Announce Type: replace Abstract: The Lindblad master equation is a foundational tool for modeling the dynamics of open quantum systems. As its use has extended far beyond its original domain, the boundaries of its validity have grown opaque. In particular, the rise of new research areas including open quantum many-body systems, non-equilibrium condensed matter, and the possibility to test its limits in driven-open quantum simulators, call for a critical revision of its regimes of applicability. In this pedagogical review, we re-examine the folklore surrounding its three standard approximations (Born, Markov, and Rotating Wave Approximation), as we build our narrative by employing a series of examples and case studies accessible to any reader with a solid background on the fundamentals of quantum mechanics. As a synthesis of our work, we offer a checklist that contrasts common lore with refined expectations, offering a practical guideline for assessing the breakdown of the Lindblad framework in the problem at hand.
