Femtosecond self-diffraction as a measure of the nonlinear response spectrum
Luca Assogna, Giovanna Salvitti, Matteo Silvestri +11
Self diffraction is a four-wave mixing process proportional to the square modulus of third-order nonlinearity susceptibility , which is related to the material's electron…

Enhanced vibrational optical activity by near-zero index chiral effective media
Ashis Paul, Matteo Venturi, Raju Adhikary +8
The enhancement of the inherently weak optical activity of solvated molecules by superchiral fields, crucial for detecting their chirality, is a research frontier of photonics and…
