Application of the exact-factorization density-functional perturbation approach to pentacene crystal and monolayer MoS2
Rachel Steinitz-Eliyahu, Galit Cohen, Guy Vosco +3
Non-adiabatic effects arising from electron-phonon interactions are often neglected within the Born-Oppenheimer (BO) approximation, which assumes that electronic states adjust inst…

Exciton-Exciton Annihilation Mediated by Many-Body Coulomb and Phonon Interactions: An Ab Initio Study
Guy Vosco, Sivan Refaely-Abramson
Exciton-exciton annihilation (EEA), in which two excitons interact to generate high-energy excitations, is an important non-radiative channel in light-induced excited-state relaxat…

Ab-initio density-matrix approach to exciton coherence: phonon scattering, Coulomb interactions and radiative recombination
Tomer Amit, Guy Vosco, Mauro Del Ben +1
Relaxation processes following light excitation in semiconductors are key in materials-based quantum technology applications. These processes are broadly studied in atomically thin…
