Title: CP-violating inflation Abstract: I will introduce the novel phenomenon of CP-violating inflation which arises in models with several scalar doublets. The inert (without vacuum expectation value) doublets have a non-minimal coupling to gravity and play the role… Read More

Title: Causality in Quantum Field Theory Abstract: In 1993 , Rafael Sorkin argued that standard quantum measurement theory and relativistic causality are not compatible because of the existence of entangled quantum states . He showed this by devising experiments using entangled states which… Read More
