Application of perturbation theory to finding vibrational frequencies of a spheroid
M. O. Nestoklon, L. Saviot, S. V. Goupalov
We apply perturbation theory of boundary conditions, originally developed by A.B. Migdal and independently by S.A. Moszkowski for deformed atomic nuclei, to finding eigenfrequencie…

Confined acoustic phonons in CsPbI3 nanocrystals explored by resonant Raman scattering on excitons
Carolin Harkort, Ina V. Kalitukha, Nataliia E. Kopteva +8
Optical properties of the lead halide perovskites nanocrystals are controlled by confined excitons and rich spectrum of confined acoustic and optical phonons. We study experimental…

Strong shape-dependent intensity of inelastic light scattering by gold nanocrystals
Lucien Saviot, Vincent Laude
We present a numerical approach to calculate inelastic light scattering spectra from gold nanocrystals, based on the finite element method. This approach is validated by comparison…
