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…
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…
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.…
Landau diamagnetism revisited
S. Dattagupta, A. M. Jayannavar, N. Kumar
The problem of diamagnetism, solved by Landau, continues to pose fascinating issues which have relevance even today. These issues relate to inherent quantum nature of the problem,…
AC driven thermal ratchets
Debasis Dan, A. M. Jayannavar, Mangal C. Mahato
We consider the motion of a overdamped Brownian particle in periodic asymmetric potential with space dependent friction coefficient. In the presence of external time periodic forci…
