Potential-Shape Control of Work Extraction in Brownian Information Engines
A study of how the geometry of the confining potential governs the information-to-energy conversion of a Brownian information engine operating in a single heat bath with measurement-based feedback. Concave (versus convex) monostable confinement raises the achievable work bound, bistable confinement exhibits a transition between engine and refrigerator behavior with barrier height, and multistable confinement can harvest more energy still, all within the stochastic-thermodynamic bound linking work, free energy, and mutual information.
Achievable Information-Energy Exchange in a Brownian Information Engine through Potential Profiling
This paper studies how the shape of a confining potential controls information-energy exchange in a Brownian information engine, an overdamped Brownian particle in a single heat bath driven by a symm…
