Revising quantum optical phenomena in adatoms coupled to graphene nanoantennas [PDF]

open access: yesNanophotonics, 2022
Graphene flakes acting as photonic nanoantennas may sustain strong electromagnetic field localization and enhancement. To exploit the field enhancement, quantum emitters such as atoms or molecules should be positioned in such close proximity to the flake

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

open access: yesNature 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

Scattering of Ultrashort X-ray Pulses on Diamonds with NV Centers

open access: yesCrystals, 2022
The scattering of ultra-short X-ray pulses (USPs) is an important component of diffraction analysis of matter. Usually, the specific scattering of such USPs is not taken into account to determine the structure of a substance.

Specificity of scattering of ultrashort laser pulses by molecules with polyatomic structure

open access: yesScientific Reports, 2022
The theory of scattering of ultrashort laser pulses (USP) is the basis of diffraction analysis of matter using modern USP sources. At present, the peculiarities of interaction of USP with complex structures are not well developed.
