Poisson-shot-noise hybrid machines: efficiency and quasistatic divergence
Rita Majumdar, Costantino Di Bello, Ralf Metzler +2
We study stochastic models of a microscopic active heat engine, comprised of an overdamped Brownian particle trapped in a harmonic potential, and in simultaneous contact with therm…

Optimal constrained control for generally damped Brownian heat engines
Monojit Chatterjee, Viktor Holubec, Rahul Marathe
Optimization of cyclic stochastic heat engines, a topic spanning decades of research, commonly assumes fixed control or response parameters at discrete points in the cycle-a limita…

Optimizing power and efficiency of a single spin heat engine
Rita Majumdar, Monojit Chatterjee, Rahul Marathe
We study the behavior of a single spin in the presence of a time-varying magnetic field utilizing Glauber dynamics. We engineer the system to function as an engine by changing the…
