1 5 Se p 20 07 Efficiency and Current in a correlated ratchet

We present a detailed study of the transport and the efficiency of a ratchet system in a periodic potential in the presence of correlated noises. The current and the efficiency of the system are investigated. It is found that, when the potential is spatially symmetric, the correlation between the two noises can induce a net transport. The efficiency shows many interesting features as a function...

Efficiency of the SQUID ratchet driven by external current

We study theoretically the efficiency of an asymmetric superconducting quantum interference device (SQUID)which is constructed as a loopwith three capacitively and resistively shunted Josephson junctions. Two junctions are placed in series in one arm and the remaining one is located in the other arm. The SQUID is threaded by an externalmagnetic flux and driven by an external current of both con...

Nonsinusoidal current and current reversals in a gating ratchet.

In this work, the ratchet dynamics of Brownian particles driven by an external sinusoidal (harmonic) force is investigated. The gating ratchet effect is observed when another harmonic is used to modulate the spatially symmetric potential in which the particles move. For small amplitudes of the harmonics, it is shown that the current (average velocity) of particles exhibits a sinusoidal shape as...

Symmetries of the ratchet current.

Recent advances in nonequilibrium statistical mechanics shed new light on the ratchet effect. The ratchet motion can thus be understood in terms of symmetry (breaking) considerations. We introduce an additional symmetry operation besides time reversal, that switches between two modes of operation. That mode reversal combined with time reversal decomposes the nonequilibrium action so as to clari...

Signal mixing in a ratchet device: commensurability and current control

Rectification current in overdamped ratchets can be easily controlled by applying two driving signals and tuning either their relative phase or their frequency ratio. The interplay of the two inputs generates intriguing transport mechanisms that can be implemented to optimize shuttling and separation of particles in a variety of physical and technological applications. PACS. 05.40.-a Fluctuatio...
