International audience; In a recent work [A. Nassereddine et al., Small 2021, 17, 2104571] we reported the atomic-scale structure and dynamics of sub-4 nm sized Au nanoparticles (NPs) supported on titania in H2 at atmospheric pressure obtained by usi

L’absence d’ordre à longue distance, par opposition à l’état cristallin, et le phénomène de la transition vitreuse sont les principaux critères qui distinguent le verre des autres états de la matière. Dans cet article, nous revenons sur

The emergence of new nanoporous materials, based e.g. on 2D materials, offers new avenues for water filtration and energy. There is accordingly a need to investigate the molecular mechanisms at the root of the advanced performances of these systems i

Fano factor, $\Delta T$-noise and cross-correlations in double quantum dots

Autor: Crépieux, A., Duong, T. Q., Lavagna, M.

We present a theoretical study of electrical current fluctuations and finite-frequency noise in a double quantum dot connected to two electron reservoirs with the aim of deriving the Fano factor, the $\Delta T$-noise and the cross-correlations. This
