    A single-mode microcavity with an embedded Aharonov-Bohm quantum ring, which is pierced by a magnetic flux and subjected to a lateral electric field, is studied theoretically. It is shown that external electric and magnetic ...
  • All-frequency reflectionlessness 

    Philbin, Thomas G. (IOP Publishing, 2015-12-11)
    We derive planar permittivity profiles that do not reflect perpendicularly exiting radiation of any frequency. The materials obey the Kramers-Kronig relations and have no regions of gain. Reduction of the Casimir force by ...

    We investigate the optoelectronic properties of novel graphene/FeCl3-intercalated few-layer graphene (FeCl3-FLG, dubbed graphexeter) heterostructures using photovoltage spectroscopy. We observe a prominent photovoltage ...
  • All-Optical Generation of Surface Plasmons in Graphene 

    Constant, Thomas J.; Hornett, Samuel M.; Chang, D.E.; Hendry, Euan (Cornell University, 2015-05-01)
    Here we present an all-optical plasmon coupling scheme, utilising the intrinsic nonlinear optical response of graphene. We demonstrate coupling of free-space, visible light pulses to the surface plasmons in a planar, ...

    Tamagnini, F; Novelia, J; Kerrigan, TL; Brown, JT; Tsaneva-Atanasova, Krasimira; Randall, AD (Frontiers, 2015-10-14)
    Amyloidopathy involves the accumulation of insoluble amyloid b (Ab) species in the brain’s parenchyma and is a key histopathological hallmark of Alzheimer’s disease (AD). Work on transgenic mice that overexpress Ab ...
  • Altered intrinsic pyramidal neuron properties and pathway-specific synaptic dysfunction underlie aberrant hippocampal network function in a mouse model of Tauopathy. 

    Booth, Clair A.; Witton, J; Nowacki, J; Tsaneva-Atanasova, Krasimira; Jones, MW; Randall, AD; Brown, JT (Society for Neuroscience -, 2016-01-13)
    The formation and deposition of tau protein aggregates is proposed to contribute to cognitive impairments in dementia by disrupting neuronal function in brain regions, including the hippocampus. We used a battery of in ...
  • An alternative calculation of the Casimir forces between birefringent plates 

    Philbin, Thomas G.; Leonhardt, Ulf (American Physical Society, 2008)
    Barash has calculated the Casimir forces between parallel birefringent plates with optical axes parallel to the plate boundaries [Izv. Vyssh. Uchebn.\ Zaved., Radiofiz., {\bf 12}, 1637 (1978)]. The interesting new feature ...
