Phonon spectra of ultrathin GaAs/AlAs superlattices: An<i>ab initio</i>calculation

Stefano Baroni , Paolo Giannozzi , Elisa Molinari

Phonon spectra of ultrathin (GaAs${)}_{\mathrm{n}}$(AlAs${)}_{\mathrm{n}}$ (001) superlattices are studied theoretically using linear-response density-functional techniques. Res...

Cumulant series expansion of hybrid nonlinear moments of complex random variables

Gaetano Scarano

A general theorem for zero-memory nonlinear transformations of complex stochastic processes is presented. It is shown that, under general conditions, the cross covariance betwee...
