Electrically controlled terahertz magneto-optical phenomena in continuous and patterned graphene

Nature Communications, 2017
Time reversal symmetry breaking gives rise to magnetic circular dichroism and Faraday rotation in graphene. The authors use terahertz magneto-electro-optical spectroscopy to demonstrate that electrostatic doping at a fixed magnetic field allows inversion

Circular Dichroism of DNA [PDF]

European Journal of Biochemistry, 1970
The circular dichroism of sixteen DNA samples from fourteen species has been determined. Plots of molar ellipticity against base composition show considerable scatter, which is much too great to be accounted for in terms of reproducibility of materials and measurements.

A broadband silicon quarter-wave retarder for far-infrared spectroscopic circular dichroism

, 2014
The high brightness, broad spectral coverage and pulsed characteristics of infrared synchrotron radiation enable time-resolved spectroscopy under throughput-limited optical systems, as can occur with the high-field magnet cryostat systems used to study ...

Optical chirality from dark-field illumination of planar plasmonic nanostructures [PDF]

, 2017
Dark-field illumination is shown to make planar chiral nanoparticle arrangements exhibit circular dichroism in extinction analogous to true chiral scatterers.

Circular dichroism of chiral Majorana states

Beilstein Journal of Nanotechnology, 2018
Background: Majorana states in condensed matter devices may be of a localized nature, such as in hybrid semiconductor/superconductor nanowires, or chirally propagating along the edges such as in hybrid 2D quantum-anomalous Hall/superconductor structures ...

Exploring small energy scales with x-ray absorption and dichroism

, 2016
Soft x-ray linear and circular dichroism (XLD, XMCD) experiments at the Ce M$_{4,5}$ edges are being used to determine the energy scales characterizing the Ce $4f$ degrees of freedom in the ultrathin ordered surface intermetallic CeAg$_x$/Ag(111).

Stabilisation of Na,K-ATPase structure by the cardiotonic steroid ouabain [PDF]

, 2013
Cardiotonic steroids such as ouabain bind with high affinity to the membrane-bound cation-transporting P-type Na,K-ATPase, leading to complete inhibition of the enzyme.
