Study of quantum current enhancement, eigenenergy spectra and magnetic moments in a multiply connected system at equilibrium
Colin Benjamin, A. M. Jayannavar
A multiply connected system in both its open and closed form variations but in equilibrium is studied using quantum waveguide theory. The system exhibits remarkable features, in it…
Wave attenuation to clock sojourn times
Colin Benjamin, A. M. Jayannavar
The subject of time in quantum mechanics is of perennial interest especially because there is no observable for the time taken by a particle to transmit (or reflect) from a particu…
Dephasing via stochastic absorption: A case study in Aharonov-Bohm oscillations
Colin Benjamin, A. M. Jayannavar
The Aharonov-Bohm ring has been the mainstay of mesoscopic physics research since its inception. In this paper we have dwelt on the problem of dephasing of AB oscillations using a…
Quantum current enhancement effect in hybrid rings at equilibrium
Colin Benjamin, A. M. Jayannavar
Current enhancement- a novel quantum phenomena is found to occur in a mesoscopic hybrid ring at equilibrium. The hybrid system is described by a ring with bubble which is in turn c…
Effect of quantum entanglement on Aharonov-Bohm oscillations, spin-polarized transport and current magnification effect
A. M. Jayannavar
We present a simple model of transmission across a metallic mesoscopic ring. In one of its arm an electron interacts with a single magnetic impurity via an exchange coupling. We sh…
Inhomogeneous Systems and their Rectification Properties
A. M. Jayannavar
We explore the possibility of obtaining unidirectional current in a symmetric (periodic) potential system without the application of any obvious (apparent) externally applied bias.…
