Effect of magnetic flux and of electron momentum on the transmission amplitude in the Aharonov-Bohm ring
M. V. Amaresh Kumar, Debendranath Sahoo
A characterization of the two-terminal open-ring Aharonov-Bohm interferometer is made by analyzing the phase space plots in the complex transmission amplitude plane. Two types of p…
Mixing quantum and classical mechanics and uniqueness of Planck's constant
Debendranath Sahoo
Observables of quantum or classical mechanics form algebras called quantum or classical Hamilton algebras respectively (Grgin E and Petersen A (1974) {\it J Math Phys} {\bf 15} 764…
Aharonov-Bohm oscillations and spin transport in a mesoscopic ring with a magnetic impurity
Sandeep K. Joshi, Debendranath Sahoo, A. M. Jayannavar
We present a detailed analysis of the Aharonov-Bohm (AB) interference oscillations manifested through transmission of an electron in a mesoscopic ring with a magnetic impurity atom…
Loss of interference in an Aharonov-Bohm ring
Sandeep K. Joshi, Debendranath Sahoo, A. M. Jayannavar
We study a simple model of dephasing of Aharonov-Bohm oscillations in the transmission of an electron across a mesoscopic ring. A magnetic impurity in one of the arms of the ring c…
Role of quantum entanglement due to a magnetic impurity on current magnification effect in mesoscopic open rings
Colin Benjamin, Sandeep K. Joshi, Debendranath Sahoo +1
We study the current magnification effect in presence of exchange scattering of electron from a magnetic impurity placed in one arm of an open mesoscopic ring. The exchange interac…

Sandeep K. Joshi, Debendranath Sahoo, A. M. Jayannavar
We present a detailed analysis of the Aharonov-Bohm interference oscillations manifested through transmission of an electron in a mesoscopic ring with a magnetic impurity atom inse…
