Tunable magnon emission from a nano-optomagnet
Anna Duvakina, Vage Karakhanyan, Mingran Xu +6
The growing demand for dense, energy-efficient, and high-frequency signal processing continues to drive device miniaturization. While downscaling remains a central challenge, magno…
Optomagnetism with plasmonic skyrmion
Vage Karakhanyan, Thierry Grosjean
Research at the frontier between optics and magnetism is revealing a wealth of innovative phenomena and avenues of exploration. Optical waves are demonstrating the capacity to indu…
Optical spin waves
Vage Karakhanyan, Roland Salut, Miguel Suarez +2
Chirality is inherent to a broad range of systems, including in solid-state and wave physics. The precession (chiral motion) of electron spins in magnetic materials, forming spin w…
Seven-probe scintillator dosimeter for treatment verification in HDR-brachytherapy
Mathieu Gonod, Miguel Angel Suarez, Carlos Chacon Avila +7
Purpose: We introduce a novel concept of a compact multiprobe scintillator detector and demonstrate its applicability in HDR-brachytherapy. Our fabricated seven-probe system is suf…
Inverse-Faraday effect from the orbital angular momentum of light
Vage Karakhanyan, Clément Eustache, Yannick Lefier +1
It is usually admitted that the inverse Faraday effect (IFE) originates from the spin angular momentum (SAM) of light. In this paper, we evidence that part of the IFE in a metal is…
Optomagnets in nonmagnetic plasmonic nanostructures
Vage Karakhanyan, Yannick Lefier, Clément Eustache +1
Using a hydrodynamic model of the free electron gas of metal, we theoretically investigate optically-induced DC current loops in a plasmonic nanostructure. Such current loops origi…
Acoustic Phonon Sideband Dynamics During Polaron Formation in a Single Quantum Dot
Daniel Wigger, Vage Karakhanyan, Christian Schneider +5
When an electron-hole pair is optically excited in a semiconductor quantum dot the host crystal lattice needs to adapt to the presence of the generated charge distribution. Therefo…
