چکیده
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.

On the other hand, powdered drugs are widely used in hospitals; however, drug mixture is a very time-consuming process. The objective of this invention was to acc...
متن کاملClosed-loop control strategy with improved current for a flashing ratchet
– We show how to switch on and off the ratchet potential of a collective Brownian motor, depending only on the position of the particles, in order to attain a current higher than or at least equal to that induced by any periodic flashing. Maximization of instant velocity turns out to be the optimal protocol for one particle but is nevertheless defeated by a periodic switching when a sufficientl...
متن کاملQuantum rectifiers from harmonic mixing
– We investigate dissipative quantum transport in extended periodic systems that are subjected to electric harmonic mixing fields Ehm(t) = E1 cos(Ωt)+E2 cos(2Ωt+φ). Although such a drive possesses no net bias on average, the interplay of quantum dissipation and nonlinear response causes a finite directed current. We thus discover the paradigm of a dissipative quantum rectifier. The quantum curr...
