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…

XUV plasmonic waveguides by near-zero index heterostructures
Luca Assogna, Carino Ferrante, Alessandro Ciattoni +1
The lack of transmissive photonic components in the extreme ultra-violet (XUV) constitutes a challenge for micro/nano-metric confinement. Here, we theoretically design a novel appr…
