Magnetic Phase Transitions driven by non-equilibrium spins (2008)
Siddiqui, L., Zainuddin, A. N. M., Datta, S.
It is well-known that the Curie temperature, and hence the magnetization, in diluted magnetic semiconductor like GaMnAs can be controlled by changing the equilibrium density of holes in the material....
Electronic transport driven spin-dynamics (2008)
Siddiqui, L., Saha, D., Datta, S., Bhattacharya, P.
We propose a model to explore the dynamics of spin-systems coupled by exchange interaction to the conduction band electrons of a semiconductor material that forms the channel in a...
The role of many-particle excitations in Coulomb blockaded transport (2008)
Muralidharan, Bhaskaran, Siddiqui, L, Ghosh, A W
We discuss the role of electron-electron and electron-phonon correlations in current flow in the Coulomb blockade regime, focusing specifically on non-trivial signatures arising from the breakdown of...
Phonon runaway in carbon nanotube quantum dots (2008)
Siddiqui, L, Ghosh, A W, Datta, Supriyo
We explore electronic transport in a nanotube quantum dot strongly coupled with vibrations and weakly with leads and the thermal environment. We show that the recent observation of anomalous...
Role of Many-particle excitations in Coulomb Blockaded Transport (2008)
Muralidharan, B., Siddiqui, L., Ghosh, A. W.
We discuss the role of electron-electron and electron-phonon correlations in current flow in the Coulomb Blockade regime, focusing specifically on nontrivial signatures arising from the break-down of...
Phonon runaway in nanotube quantum dots (2006)
Siddiqui, L., Ghosh, A. W., Datta, S.
We explore electronic transport in a nanotube quantum dot strongly coupled with vibrations and weakly with leads and the thermal environment. We show that the recent observation of anomalous...
