Wasserstein speed limits for Langevin systems (2312.07788v2)
Published 12 Dec 2023 in math-ph, cs.SY, eess.SY, math.MP, and math.OC
Abstract: Physical systems transition between states with finite speed that is limited by energetic costs. In this work, we derive bounds on transition times for general Langevin systems that admit a decomposition into reversible and irreversible dynamics, in terms of the Wasserstein distance between states and the energetic costs associated with respective reversible and irreversible currents. For illustration we discuss Brownian particles subject to arbitrary forcing and an RLC circuit with time-varying inductor.
