High-throughput screening of Weyl semimetals

Nicola Marzari, Davide Grassano, Davide Campi

Topological Weyl semimetals represent a novel class of nontrivial materials, where band crossings with linear dispersions take place at generic momenta across reciprocal space. These crossings give rise to low -energy properties akin to those of Weyl fermi ...

Evidence for a spin acoustic surface plasmon from inelastic atom scattering

Davide Campi

Closed-shell atoms scattered from a metal surface exchange energy and momentum with surface phonons mostly via the interposed surface valence electrons, i.e., via the creation of virtual electron-hole pairs. The latter can then decay into surface phonons v ...

Gas Transport across Carbon Nitride Nanopores: A Comparison of van der Waals Functionals against the Random-Phase Approximation

Nicola Marzari, Kumar Varoon Agrawal, Nicola Colonna, Davide Campi

C2N is an ordered two-dimensional carbon nitride with a high density (1.7 x 10 14 cm(-2)) of 3.1 angstrom-sized nanopores, making it promising for highflux gas sieving for energy-efficient He and H-2 purification. Herein, we discuss the accurate calculatio ...
