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…

Photon momentum enabled light absorption in bulk silicon
Sergey S. Kharintsev, Aleksey I. Noskov, Elina I. Battalova +6
Photons do not carry sufficient momentum to induce indirect optical transitions in semiconducting materials such as silicon, necessitating the assistance of lattice phonons to cons…
