Chiroptical studies on brevianamide B : vibrational and electronic circular dichroism confronted [PDF]
, 2015 Chiroptical spectroscopy, such as electronic circular dichroism (ECD) and vibrational circular dichroism (VCD) are highly sensitive techniques to probe molecular conformation, configuration, solvation and aggregation.

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

Chiral Surface Waves for Enhanced Circular Dichroism [PDF]
, 2017 We present a novel chiral sensing platform that combines a one-dimensional photonic crystal design with a birefringent surface defect. The platform sustains simultaneous transverse electric and transverse magnetic surface modes, which are exploited to ...

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 ...

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.

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 ...

Circular dichroism induced by Fano resonances in planar chiral oligomers
, 2015 We present a general theory of circular dichroism in planar chiral nanostructures with rotational symmetry. It is demonstrated, analytically, that the handedness of the incident field's polarization can control whether a nanostructure induces either ...
