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.

Bioinspired Magneto-optical Bacteria [PDF]

open access: yesInorganic Chemistry, 2014
"Two-in-one" magneto-optical bacteria have been produced using the probiotic Lactobacillus fermentum for the first time. We took advantage of two features of bacteria to synthesize this novel and bifunctional nanostructure: their metal-reducing properties, to produce gold nanoparticles, and their capacity to incorporate iron oxide nanoparticles at ...

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 ...

Magneto-optical cooling of atoms [PDF]

open access: yesOptics Letters, 2014
We propose an alternative method to laser cooling. Our approach utilizes the extreme brightness of a supersonic atomic beam, and the adiabatic atomic coilgun to slow atoms in the beam or to bring them to rest. We show how internal-state optical pumping and stimulated optical transitions, combined with magnetic forces can be used to cool the ...

Femtosecond electron and spin dynamics probed by nonlinear optics [PDF]

open access: yes, 1999
A theoretical calculation is performed for the ultrafast spin dynamics in nickel using an exact diagonalization method. The present theory mainly focuses on a situation where the intrinsic charge and spin dynamics is probed by the nonlinear (magneto ...

Integrating planar photonics for multi-beam generation and atomic clock packaging on chip

open access: yesLight: Science & Applications, 2023
The commercialization of atomic technologies requires replacing laboratory-scale laser setups with compact and manufacturable optical platforms. Complex arrangements of free-space beams can be generated on chip through a combination of integrated ...

Magnetoplasmonic design rules for active magneto-optics

open access: yes, 2014
Light polarization rotators and non-reciprocal optical isolators are essential building blocks in photonics technology. These macroscopic passive devices are commonly based on magneto-optical Faraday and Kerr polarization rotation.
