Controlled Coulomb effects in core-shell quantum rings
Anna Sitek, Miguel Urbaneja Torres, Kristinn Torfason +2
We analyse theoretically the possibilities of contactless control of in-gap states formed by a pair of electrons confined in a triangular quantum ring. The in-gap states are corner…
Normal and inverted hysteresis in perovskite solar cells
George Alexandru Nemnes, Cristina Besleaga, Viorica Stancu +6
Hysteretic effects are investigated in perovskite solar cells in the standard FTO/TiO/CHNHPbICl/spiro-OMeTAD/Au configuration. We report normal (NH) and inv…
Thermoelectric Current and Coulomb-Blockade Plateaus in a Quantum Dot
Kristinn Torfason, Andrei Manolescu, Sigurdur I. Erlingsson +1
A Generalized Master Equation (GME) is used to study the thermoelectric currents through a quantum dot in both the transient and steady-state regime. The two semi-infinite leads ar…
Excitation of collective modes in a quantum flute
Kristinn Torfason, Andrei Manolescu, Valeriu Molodoveanu +1
We use a generalized master equation (GME) formalism to describe the non-equilibrium time-dependent transport of Coulomb interacting electrons through a short quantum wire connecte…
Generalized Master equation approach to mesoscopic time-dependent transport
Kristinn Torfason, Andrei Manolescu, Valeriu Molodoveanu +1
We use a generalized Master equation (GME) formalism to describe the non-equilibrium time-dependent transport through a short quantum wire connected to semi-infinite biased leads.…
Magnetotransport in a time-modulated double quantum point contact system
Chi-Shung Tang, Kristinn Torfason, Vidar Gudmundsson
We report on a time-dependent Lippmann-Schwinger scattering theory that allows us to study the transport spectroscopy in a time-modulated double quantum point contact system in the…
Coherent magnetotransport and time-dependent transport through split-gated quantum constrictions
Kristinn Torfason, Chi-Shung Tang, Vidar Gudmundsson
The authors report on modeling of transport spectroscopy in split-gate controlled quantum constrictions. A mixed momentum-coordinate representation is employed to solve a set of ti…
