Bio
SB’s scientific interests are at the frontier between condendesed-matter theory and simulation, with a penchant for software engineering and high-performance computing: he likes to develop methods to compute properties and simulate processes previously deemed inaccessible to scientific computation, to implement them in high-performance computer codes, and to apply them to problems that are scientifically and technologically relevant. He is largely credited for the introduction of density-functional perturbation theory (DFPT), a methodology that is considered the state of the art for the computation of lattice dynamical properties in solids, including phonon frequencies and lifetimes. He has pioneered O(N) methods in electronic-structure theory and he has also introduced important innovations in quantum stochastic simulations, including the first application of Auxiliary-Fields Quantum Monte Carlo to electronic-structure problems and the introduction of Reptation Quantum Monte Carlo, a method that allows computing with great precision the low-lying spectrum of interacting bosons, with prominent applications to Helium droplets and extensions to interacting fermions. Recently, he has successfully extended DFPT so as to encompass electronic excited states through time-dependent density-functional and many-body perturbation theories. He has thoroughly applied these methodological innovations to a number of problems in semiconductor physics, the chemical physics of metal surfaces, and, more recently, molecular and magnetic spectroscopies. Over the past 10 years SB has given important contributions to the theory and numerical simulation of adiabatic heat and charge transport in liquid and disordered systems.
