Investigation on the directional transportation of coupled Brownian motors with asymmetric friction

Abstract: <sec>Biological molecular motors exist in cells widely. They can make use of intracellular free energy to complete all kinds of internal biological transports by transforming chemical energy into mechanical energy. The kind of directional movement of biological molecular motors plays a very important role in intracellular material transportation. In order to study the transport mechanism of molecular motors further, a large number of ratchet models are proposed, such as rocking ratchets and flashing ratc… Show more

“…Similarly, when a Brownian motor moves in a periodic potential, there are various random fluctuations such as the thermal fluctuation. Gaussian noises are commonly selected to model the thermal fluctuation [47][48][49][50]. In a Gaussian distribution the tails of the probability density fall off exponentially, and the mean squared displacement in the passive motion grows linearly with time.…”
