Research Interests

My research interest is in the physics of quantum spins, particularly as model systems for the study of decoherence processes. In the past I have designed and performed a variety of experiments (nuclear-, electron-, muon-, and beta-detected- spin resonance, SQUID magnetometery , susceptibility) at ultra low temperatures, to study the spin dynamics of molecular nanomagnets and develop the theoretical description of their quantum behavior. My current project is the development of a spin qubit based on the electron of single a phosphorus dopant in silicon, from the nanofabrication of the devices to the coherent manipulation of the electron spin state.  This also involves the study of the fundamental physical properties of superconducting and magnetic silicides to be used as electron reservoirs for spin-to-charge conversion. As side projects, I am interested in quantum phase transitions in 1D superconductors, chaos in spin systems, and the transition from quantum to classical behavior in mesoscopic objects.
