Asymmetric q-Gaussian functions generalizing the Breit-Wigner-Fano functions

Previous studies (Sparavigna, 2023) have demonstrated the Tsallis q-Gaussian functions suitable for the analysis of Raman spectra. The q-Gaussians are symmetric functions that can be used for simulating different line shapes of Raman bands. Here we propose an asymmetric form of the q-Gaussians, to generalize the Breit-Wigner-Fano profiles. Some examples are proposed, in particular a case study of the LO band of SiC.
