Generation and Measurement of Non Equilibrium Spin Currents in Two Terminal Systems
T. P. Pareek, A. M. Jayannavar
Generation and measurement of non-equilibrium spin current in two probe configuration is discussed. It is argued and shown that spin current can be generated in two terminal non-ma…
Hartman effect in presence of Aharanov Bohm flux
Swarnali Bandopadhyay, Raishma Krishnan, A. M. Jayannavar
The Hartman effect for the tunneling particle implies the independence of group delay time on the opaque barrier width, with superluminal velocities as a consequence. This effect i…
Equilibrium currents in quantum double ring system: A non-trivial role of system-reservoir coupling
Colin Benjamin, A. M. Jayannavar
Amperes law states that the magnetic moment of a ring is given by current times the area enclosed. Also from equilibrium statistical mechanics it is known that magnetic moment is t…
Features in Evanescent Aharonov-Bohm interferometry
Colin Benjamin, A. M. Jayannavar
In this work we analyze an Aharonov-Bohm interferometer in the tunneling regime. In this regime, current magnification effect which arises in presence of transport currents is abse…
Survival of periodicity in presence of incoherence in asymmetric Aharonov-Bohm rings
Colin Benjamin, Swarnali Bandopadhyay, A. M. Jayannavar
Magneto conductance oscillations periodic in flux with periodicity and are seen in asymmetric Aharonov-Bohm rings as a function of density of electrons or Fermi w…
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…
