Features of magneto-optics of dichroic cholesteric liquid crystals

open access: yesКомпьютерная оптика, 2021
In this work, magneto-optical properties of a dichroic cholesteric liquid-crystal layer are theoretically investigated at large values of the magneto-optical parameter.

Study of Light Polarization by Ferrofluid Film Using Jones Calculus

open access: yesCondensed Matter, 2022
We studied the polarized light patterns obtained using a thin film of ferrofluid subjected to an applied magnetic field. We obtained patterns of polarized light with magnetic field configurations between parallel plates, monopolar, tetrapolar, and ...

Ultrafast Demagnetization Measurements Using Extreme Ultraviolet Light: Comparison of Electronic and Magnetic Contributions

open access: yesPhysical Review X, 2012
Ultrashort pulses of extreme ultraviolet light from high-harmonic generation are a new tool for probing coupled charge, spin, and phonon dynamics with element specificity, attosecond pump-probe synchronization, and time resolution of a few femtoseconds ...

Quantum Magneto-Optics in Graphene

open access: yesPhotonics, 2015
The optical conductivity of graphene in quantizing magnetic fields is studied. Both dynamical conductivities, longitudinal and Hall’s, are analytically evaluated. The conductivity peaks are explained in terms of electron transitions.

Photospheric high-frequency acoustic power excess in sunspot umbra: signature of magneto-acoustic modes [PDF]

open access: yes, 2013
We present observational evidence for the presence of MHD (magnetohydrodynamic) waves in the solar photosphere deduced from SOHO/MDI (Solar and Heliospheric Observatory/Michelson Doppler Imager) Dopplergram velocity observations.

Surface-plasmon-polariton-driven narrow-linewidth magneto-optics in Ni nanodisk arrays

open access: yesNanophotonics, 2019
The field of magnetoplasmonics exploits interactions between light and magnetic matter at the nanoscale for light manipulation and resonant magneto-optics. One of the great challenges of this field is overcoming optical losses in magnetic metals.
