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…
Quantum spin pumping with adiabatically modulated magnetic barrier's
Ronald Benjamin, Colin Benjamin
A quantum pump device involving magnetic barriers produced by the deposition of ferro magnetic stripes on hetero-structure's is investigated. The device for dc- transport does not…
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…
