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…
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…
