Batch scheduling to minimize the weighted number of tardy jobs
(Pergamon Press, 2007)In this paper, we address a single-machine scheduling problem with due dates and batch setup times to minimize the weighted number of tardy jobs. We give a pseudo-polynomial dynamic program and a fully-polynomial approximation ... -
Decoherence in open quantum systems : a realistic approach
(Bilkent University, 2006)Decoherence mechanisms of opcu quantum systems ın intcraction with an enviromental bath is investigated using the master equation formalism. Widely used two-level approximation is questioned. -
Energy transfer rate in Coulomb coupled quantum wires
(American Institute of Physics, 1997)We study the energy transfer rate for electrons in two parallel quantum wires due to interwire Coulomb interactions. The energy transfer rate between the wires (similar to the Coulomb drag effect in which momentum transfer ... -
Overdetermined systems of linear equations

Plasmon-LO-phonon coupling effects on the drag rate in double quantum-well systems
(Elsevier, 1997)We study the Coulomb drag rate for electrons in a double-quantum-well structure taking into account the electron-optical phonon interactions. The full wave vector and frequency dependent random-phase approximation (RPA) ... -
The Smoluchowski-Kramers limit of stochastic differential equations with arbitrary state-dependent friction
(Springer, 2015)We study a class of systems of stochastic differential equations describing diffusive phenomena. The Smoluchowski-Kramers approximation is used to describe their dynamics in the small mass limit. Our systems have arbitrary ...
