Statistical Insight into the Correlation of Geometry and Spectral Emission in Network Lasers
Camillo Tassi, Riccardo Mannella, Andrea Tomadin +2
Optically active networks show feature-rich emission that depends on the fine details of their geometry, and find diverse applications in random lasers, sensing devices and photoni…

Numerical Integration of stochastic differential equations: The Heun Algorithm Revisited and Itô-Stratonovich Calculus
Riccardo Mannella
The widely used Heun algorithm for the numerical integration of stochastic differential equations (SDEs) is critically re-examined. We discuss and evaluate several alternative impl…

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…
