Singlet-triplet filtering and entanglement in a quantum dot structure
G. Giavaras, J. H. Jefferson, M. Fearn +1
We consider two interacting electrons in a semiconductor quantum dot structure which consists of a small dot within a larger dot, and demonstrate a singlet-triplet filtering mechan…
Electronic Properties of Alkali- and Alkaline-Earth-Intercalated Silicon Nanowires
S. Sirichantaropass, V. M. García-Suárez, C. J. Lambert
We present a first-principles study of the electronic properties of silicon clathrate nanowires intercalated with various types of alkali or alkaline-earth atoms. We find that the…
Quantum entanglement generation with surface acoustic waves
G. Giavaras, J. H. Jefferson, A. Ramsak +2
We propose a scheme to produce spin entangled states for two interacting electrons. One electron is bound in a well in a semiconductor quantum wire and the second electron is trans…
Controlled electron transport through single molecules
C. J. Lambert, I. M. Grace, T. Papadopoulos
Using a first principles approach, we study the electron transport properties of a new class of molecular wires containing fluorenone units, whose features open up new possibilitie…
Control of electron transport through Fano resonances in molecular wires
Theodoros Papadopoulos, Iain Grace, Colin Lambert
Using a first principles approach, we study the electron transport properties of two molecules of length 2.5nm which are the building blocks for a new class of molecular wires cont…
Quantized invariant tori in Andreev billiards of mixed phase space
Z. Kaufmann, A. Kormányos, J. Cserti +1
Comparing the results of exact quantum calculations and those obtained from the EBK-like quantization scheme of Silvestrov et al [Phys. Rev. Lett. 90, 116801 (2003)] we show that t…
