Off-Resonance Enhancement of the Refractive Index via Indirect Optical Transitions
E. I. Battalova, A. I. Minibaev, A. V. Petrov +1
At resonance, the optical response of a homogeneous medium to incident light is governed by temporal dispersion, which induces changes in the refractive index (RI). However, recent…

Heat Generation in Spatially Confined Solids Through Electronic Light Scattering
Sergey Kharintsev, Elina Battalova
In this Letter, we study the optical heating of spatially dispersive solids due to electronic light scattering (ELS), a phenomenon driven by indirect optical transitions. In this p…

Extreme electron-photon interaction in perovskite glass
S. S. Kharintsev, E. I. Battalova, I. A. Matchenya +2
The interaction of light with solids can be dramatically enhanced owing to electron-photon momentum matching. This mechanism is driven by either quantum confinement or long-range s…
