Recent Developments of the VOXES Von Hamos X-ray Spectrometer for Laboratory XES and XAS Studies

Simone Manti, Alberto Clozza, Gabriel Moskal +5

VOXES is a Von Hamos X-ray spectrometer developed at the INFN National Laboratories of Frascati for high-resolution laboratory X-ray spectroscopy in the 5--20~keV range. It uses cu…

Quantum point defects in 2D materials: The QPOD database

Fabian Bertoldo, Sajid Ali, Simone Manti +1

Atomically thin two-dimensional (2D) materials are ideal hosts of quantum defects as they offer easier control, manipulation and read-out of defect states compared to bulk systems.…

Fundamental Limits on Clock Precision from Spacetime Uncertainty in Quantum Collapse Models

Nicola Bortolotti, Catalina Curceanu, Lajos Diósi +2

Models of spontaneous wavefunction collapse explain the quantum-to-classical transition without invoking the von Neumann measurement postulate. Prominent frameworks, such as the Di…

Selenium and the role of defects for photovoltaic applications

Hadeel Moustafa, Jiban Kangsabanik, Fabian Bertoldo +4

We present first principles calculations of the electronic properties of trigonal selenium with emphasis on photovoltaic applications. The band gap and optical absorption spectrum…

Exploring and machine learning structural instabilities in 2D materials

Simone Manti, Mark Kamper Svendsen, Nikolaj R. Knøsgaard +2

We address the problem of predicting the zero-temperature dynamical stability (DS) of a periodic crystal without computing its full phonon band structure. Here we report the eviden…
