Tunnelling magnetoresistance anomalies of a Coulomb blockaded quantum dot
Piotr Stefanski
We consider quantum transport and tunneling magnetoresistance (TMR) through an interacting quantum dot in the Coulomb blockade regime, attached to ferromagnetic leads. We show that…
Proposal for a correlation induced spin-current polarizer
Piotr Stefanski
We propose a spin polarizer device composed of a quantum dot connected to the spin polarized leads. The spin control of the current flowing through the device is entirely due to th…
Charge dynamics effects in conductance through a large semi-open quantum dot
Piotr Stefanski, Arturo Tagliacozzo, Bogdan R. Bulka
Fano lineshapes in resonant transmission in a quantum dot imply interference between localized and extended states. The influence of the charge accumulated at the localized levels,…
Fano versus Kondo Resonances in a Multilevel "Semi-Open" Quantum Dot
Piotr Stefanski, Arturo Tagliacozzo, Bogdan R. Bulka
Linear conductance across a large quantum dot via a single level e_0 with large hybridization to the contacts is strongly sensitive to quasi-bound states localized in the dot and w…
Quantum dots as scatterers in electronic transport : interference and correlations
Piotr Stefanski
Conductance through a system consisting of a wire with side-attached quantum dots is calculated. Such geometry of the device allows to study the coexistence of quantum interference…
