Phase time for a tunneling particle
Swarnali Bandopadhyay, A. M. Jayannavar
We study the nature of tunneling phase time for various quantum mechanical structures such as networks and rings having potential barriers in their arms. We find the generic presen…
Giant coherence in driven systems
Soumen Roy, Debasis Dan, A. M. Jayannavar
We study the noise-induced currents and reliability or coherence of transport in two different classes of rocking ratchets. For this, we consider the motion of Brownian particles i…
Noise induced currents and reliability of transport in frictional ratchets
Raishma Krishnan, Debasis Dan, A. M. Jayannavar
We study the coherence of transport of an overdamped Brownian particle in frictional ratchet system in the presence of external Gaussian white noise fluctuations. The analytical ex…
