Phonon spectra, quantum geometry, and the Goldstone theorem
Guglielmo Pellitteri, Zenan Dai, Haoyu Hu +5
Phonons are essential quasi-particles of all crystals and play a key role in fundamental properties such as thermal transport and superconductivity. In particular, acoustic phonons…

Geometric effects in the Dyakonov-Shur theory of Teraherz photodetection
Riccardo Riolo, Marco Polini, Riccardo Mannella +1
Nonlinear resonances of plasma waves in field-effect transitors enable a well-known photodetection mechanism, first introduced by Dyakonov and Shur in the Nineties, especially suit…
