Molecular dynamic simulation of xenon bubble re-solution in uranium dioxide
This is a comprehensive study of two mechanisms of fission gas bubble re-solution in UO2 by molecular dynamics (MD) simulations: homogeneous re-solution and heterogeneous re-solution. For the homogeneous mechanism, a hybrid approach is employed whereby Monte Carlo (MC) simulations are used to …

Effects of vacancies and electron temperature on the electron phonon coupling in cubic silicon carbide and their connection to the inelastic thermal spike
… Perturbation Theory - Classical Electron Gas model. The coupling factor was calculated as a function of electron temperature in pristine and defective 3C-SiC, and relaxed defective cells. The electron-phonon coupling is found to depend strongly on the electronic temperature and on the presence …

Dynamics of Energy Carriers in Solids During Interaction with Ultrafast Laser Pulses
… and analyzing the measured signals with the two-temperature model (TTM), it is found that during the transient heating process, when electrons and phonons are in thermal nonequilibrium state, electrons in metal thin films can directly transfer energy to phonons in dielectric substrates. In …

Molecular Dynamics study of defect evolution mechanisms in material of interests for quantum technologies [Studio di Dinamica Molecolare dei meccanismi di evoluzione dei difetti nei materiali di interesse per le tecnologie quantistiche]
Abbiamo studiato la formazione e l'evoluzione dei difetti nel 3C–SiC utilizzando simulazioni di dinamica molecolare classica con potenziali interatomici dipendenti dall'ambiente. Il benchmarking preliminare ha incluso parametri reticolari, energie di formazione dei difetti e calcoli del punto di …
