Phenomenon of the time-reversal-violating photon polarization plane rotation by a gas placed to an electric field [PDF]

open access: yes, 1998
T-odd P-odd phenomenon of the photon polarization plane rotation (circular dichroism) is considered for an atomic (molecules) gas placed to an electric field.

Magnetic circular dichroism from the impurity band in III-V diluted magnetic semiconductors

open access: yes, 2008
The magnetic circular dichroism of III-V diluted magnetic semiconductors, calculated within a theoretical framework suitable for highly disordered materials, is shown to be dominated by optical transitions between the bulk bands and an impurity band ...

Angle-resolved x-ray circular and magnetic circular dichroisms: Definitions and applications [PDF]

open access: yes, 1996
We introduce definitions of angle-resolved x-ray circular dichroism (ARXCD) and magnetic x-ray circular dichroism (ARMXCD). As defined, the much larger effect of circular dichroism (ARXCD) is separated from the smaller magnetic (ARMXCD) effect.

Effective index of refraction, optical rotation, and circular dichroism in isotropic chiral liquid crystals [PDF]

open access: yes, 2001
This paper concerns optical properties of the isotropic phase above the isotropic-cholesteric transition and of the blue phase BP III. We introduce an effective index, which describes spatial dispersion effects such as optical rotation, circular ...

Slight Truncation Changes in Iron Oxide Nanocubes Strongly Affect Their Magnetic Properties

open access: yesAdvanced Functional Materials, EarlyView.
Subtle variations in nanoparticle morphology can lead to significant changes in functional properties. An automated shape‐fitting method captures minor differences in corner truncation between iron oxide nanocubes of similar sizes synthesized under identical conditions, revealing pronounced disparities in their magnetic and hyperthermia behavior ...

Circular Dichroism in Study of Drug Chirality

open access: yesАнтибиотики и Химиотерапия, 2020
Verapamyl substance and market verapamyl were investigated with circular dichroism. It was shown that circular dichroism provided rapid and highly efficient determination of the optic isomers and could be recommended as a method for control of drug ...

Characterization of optical parameters of breast cancer cell line - BT474 by polarimetry technique

open access: yesVietnam Journal of Science, Technology and Engineering, 2022
Breast cancer is a well-known health issue that has been a major focus for healthcare professionals for quite some time. Still, the most common noninvasive diagnostic tool - mammography - results in a high false positive rate along with risks of ...

Elliptical dichroism: operating principle of planar chiral metamaterials [PDF]

open access: yes, 2009
We employ a homogenization technique based on the Lorentz electronic theory to show that planar chiral structures (PCSs) can be described by an effective dielectric tensor similar to that of biaxial elliptically dichroic crystals. Such a crystal is shown

Circular‐Polarization‐Sensitive Organic Photodetectors with a Chiral Nanopatterned Electrode Inverse‐Designed by Genetic Algorithm

open access: yesAdvanced Functional Materials, EarlyView.
A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...
