Bernardo Barbiellini

Bernardo Barbiellini has worked on theories of modern spectroscopic techniques such as Compton scattering, positron annihilation and STM. He has developed efficient computational methods, in particular the Stochastic Gradient Approximation (SGA) for Quantum Monte Carlo simulations to extract quantum mechanical properties from molecular fragments. He has used electronic structure methods to simulate properties of various materials ranging from high temperature superconductors, colossal magneto-resistant manganites, ice and CdSe nano-particles. His investigation on the hydrogen bond is a significant step towards an understanding of biological processes from the basic laws of quantum mechanics. His more recent scientific interests are problems of excited-state physics in complex materials addressed by powerful synchrotron light sources.
