Collective Current Rectification
We consider a set of coupled underdamped ac-driven dynamical units exposed to a heat bath. The coupling scheme defines the absence/presence of certain symmetries, which in turn cause a nonzero/zero value of a mean dc-output. We discuss dynamical mechanisms of a dc-current appearance and identify current reversals with synchronization/desynchronization transitions in the collective ratchet’s dyn...
متن کاملCurrent Rectification in Dynamical Networks
We consider a network of coupled underdamped ac-driven dynamical units exposed to a heat bath. The topology of connections defines the absence/presence of certain spatial symmetries, which in turn cause nonzero/zero value of a mean dc-output. We discuss dynamical mechanisms of the rectification and identify dc-current reversals with synchronization/desynchronization transitions in the network d...
متن کاملCurrent Rectification at Quartz Nanopipet Electrodes
Ag/AgCl reference electrodes fabricated from pulled quartz tubes with orifice radii of 20 nm to 20 μm were characterized in KCl solutions of different concentrations by cyclic voltammetry. Linear current-voltage (i-V) dependence was observed with micropipet electrodes (with micrometer-sized tips) with the same concentration (0.01-1 M) of KCl inside and outside the pipet, but current rectificati...
متن کاملLeak Current Rectification in Myxicola Giant Axons
Early leak current, i.e. for times similar to the time to peak of the transient current was measured in Myxicola giant axons in the presence of tetrodotoxin. The leak current-voltage relation rectifies, showing more current for strong depolarizing pulses than expected from symmetry around the holding potential. A satisfactory practical approximation for most leak corrections is constant resting...
متن کاملBrownian motors: current fluctuations and rectification efficiency.
With this work, we investigate an often neglected aspect of Brownian motor transport, namely, the role of fluctuations of the noise-induced current and its consequences for the efficiency of rectifying noise. In doing so, we consider a Brownian inertial motor that is driven by an unbiased monochromatic, time-periodic force and thermal noise. Typically, we find that the asymptotic, time-, and no...
