Phase-Transition-Driven Hyperbolic Optical Response and Directional Polaritons in Epitaxial VO2 Thin Films
Maria Chiara Paolozzi, Annalisa D Arco, Ilaria Martinelli +10
Optical anisotropy in crystalline solids enables direction-dependent light-matter interactions and underpins a variety of advanced photonic functionalities. In this context, Vanadi…
Enhanced third harmonic response of the PtTe transition metal dichalcogenide
Leone Di Mauro Villari, Simone Grillo, Olivia Pulci +3
We investigate the third harmonic response of platinum ditelluride (PtTe), a Dirac semimetal belonging to the transition metal dichalcogenides class. Due to its topological pro…
Deep learning recognition and analysis of Volatile Organic Compounds based on experimental and synthetic infrared absorption spectra
Andrea Della Valle, Annalisa D'Arco, Tiziana Mancini +5
Volatile Organic Compounds (VOCs) are organic molecules that have low boiling points and therefore easily evaporate into the air. They pose significant risks to human health, makin…
Few-cycle THz Pulse Generation in DSTMS Crystal Pumped by a 8.3-MHz Amplified Mamyshev Oscillator
Francesco Canella, Dario Giannotti, Sara Pizzurro +6
Mamyshev oscillators are an emerging class of ultrafast fiber lasers that support exceptionally broadband spectra and few-femtosecond pulse durations, making them well-suited for n…
Search for structural differences in spike glycoprotein variants of SARS-CoV-2: Infrared Spectroscopy, Circular Dichroism and Computational Analysis
Tiziana Mancini, Nicole Luchetti, Salvatore Macis +5
The SARS-CoV-2 pandemic has led to a significant emergence of highly mutated forms of viruses with a great ability to adapt to the human host. Some mutations resulted in changes in…
Dual Optical Hyperbolicity of PdCoO and PdCrO Delafossite Single Crystals
Salvatore Macis, Annalisa DArco, Eugenio Del Re +12
Hyperbolic materials exhibit a very peculiar optical anisotropy with simultaneously different signs of the dielectric tensor components. This anisotropy allows the propagation of e…
