Modeling an efficient Brownian heat engine
Mesfin Asfaw
We discuss the effect of subdividing the ratchet potential on the performance of a tiny Brownian heat engine that is modeled as a Brownian particle hopping in a viscous medium in a…
Exploring the operation of a tiny heat engine
Mesfin Asfaw, Mulugeta Bekele
We model a tiny heat engine as a Brownian particle that moves in a viscous medium in a sawtooth potential (with or without load) assisted by placed hot and cold…
Energetics of a simple microscopic heat engine
Mesfin Asfaw, Mulugeta Bekele
We model a microscopic heat engine as a particle hopping on a one-dimensional lattice in a periodic sawtooth potential, with or without load, assisted by the thermal kicks it gets…
An adjustable Brownian heat engine
Mesfin Asfaw, Mulugeta Bekele
A microscopic heat engine is modeled as a Brownian particle in a sawtooh potential (with load) moving through a highly viscous medium driven by the thermal kick it gets from altern…
