In nature and technology, network-like systems are typically coupled and the resilience of one is aected by the others. The failure of a small fraction of elements in the system may have catastrophic...
Monte-Carlo-based spectral gain analysis for THz quantum cascade lasers
THz quantum cascade lasers Monte-Carlo-based spectral gain analysis
2011/9/14
Employing an ensemble Monte Carlo transport simulation, we self-consistently analyze the spectral gain for different THz quantum cascade laser structures, considering bound-to-continuum as well as res...
Computational approach to multifractal music
