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…

Dephasing of Aharonov-Bohm oscillations 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 interference oscillations manifested through transmission of an electron in a mesoscopic ring with a magnetic impurity atom inse…

Quantum Stochastic Absorption
Sandeep K. Joshi, Debendranath Sahoo, A. M. Jayannavar
We report a detailed and systematic study of wave propagation through a stochastic absorbing random medium. Stochastic absorption is modeled by introducing an attenuation constant…
