Quantum Transport in Graphene Nanoribbons with Realistic Edges
Patrick Hawkins, Milan Begliarbekov, Marko Zivkovic +2
Due to their unique electrical properties, graphene nanoribbons (GNRs) show great promise as the building blocks of novel electronic devices. However, these properties are strongly…
Index of refraction engineering in five level DIGS atoms
Steven A. Sagona-Stophel, James Owen Weatherall, Christopher P. Search
We present a five level atomic system in which the index of refraction of a probe laser can be enhanced or reduced below unity with vanishing absorption in the region between pairs…
Quantum Inductance and High Frequency Oscillators in Graphene Nanoribbons
Milan Begliarbekov, Stefan Strauf, Christopher P Search
Here we investigate high frequency AC transport through narrow graphene nanoribbons with topgate potentials that form a localized quantum dot. We show that as a consequence of the…
Lossless anomalous dispersion and an inversionless gain doublet via dressed interacting ground states (DIGS)
James Owen Weatherall, Christopher P. Search
Transparent media exhibiting anomalous dispersion have been of considerable interest since Wang, Kuzmich, and Dogariu [Nature {\bf 406}, 277 (2000)] first observed light propagate…
Quantum control of dispersion in electromagnetically induced transparency via interacting dressed ground states
James Owen Weatherall, Christopher P. Search
We offer a general treatment of electromagnetically induced transparency (EIT) in a five level system consisting of four metastable ground states. Two additional RF/microwave field…
Quantum bistability and spin current shot noise of a single quantum dot coupled to an optical microcavity
Ivana Djuric, Marko Zivkovic, Chris P. Search +1
Here we explore spin dependent quantum transport through a single quantum dot coupled to an optical microcavity. The spin current is generated by electron tunneling between a singl…
