Searching for Axions on a Higher Note: Third-Harmonic Generation from Colliding High-Intensity Laser Beams
Ashis Paul, Leone di Mauro Villari, Davide Tedeschi +3
We propose a new laboratory strategy to generate and detect axion-like particles via third-harmonic generation induced by two non-collinear, polarised high-intensity laser beams of…
Enantio-selective inverse Faraday effect in isotropic chiral molecular mixtures
Raju Adhikary, Ambaresh Sahoo, Matteo Silvestri +5
Enantiomeric excess detection in a chiral molecular mixture is paramount because very often opposite enantiomers exhibit profound functional dissimilarities that play decisive role…
Chirally-sensitive optical rectification by isotropic chiral media
Raju Adhikary, Luca Assogna, Ambaresh Sahoo +8
Chiroptical sensing is central to gain fundamental insight into electronic, vibrational and rotational degrees of freedom of chiral molecules, and is a cornerstone for nanomedicine…
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 electroni…
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…
