Entropy Signatures of Topological Phase Transitions
Y. M. Galperin, D. Grassano, V. P. Gusynin +5
We review the behavior of the entropy per particle in various two-dimensional electronic systems. The entropy per particle is an important characteristic of any many body system th…

Ab initio optical and energy loss spectra of transition metal monopnictides TaAs, TaP, NbAs, and NbP
Davide Grassano, Friedhelm Bechstedt, Olivia Pulci
Transition metal monopnictides represent a new class of topological semimetals with low-energy excitations, namely, Weyl fermions. We report optical properties across a wide spectr…

Detection of topological phase transitions through entropy measurements: the case of germanene
D. Grassano, O. Pulci, V. O. Shubnyi +4
We propose a characterization tool for studies of the band structure of new materials promising for the observation of topological phase transitions. We show that a specific resona…
