]]>I am a Lecturer in Mathematical Physics at the University of Melbourne. My research interest lies at the intersection of geometry, quantum information and fundamental theory. Recent works include the study of volume law entanglement of typical pure states, entanglement of quantum fields in curved spacetime, variational methods for many body quantum systems and entanglement production in unstable systems. An important overarching theme has been recently the use of Kähler geometry providing a unified mathematical framework for the study of bosonic and fermionic Gaussian states.

]]>My research focuses on scientific method and the nature of our knowledge of physics. What is the structure and content of physical theories, how are theories evaluated, and how are they extended? I have pursued these questions through philosophical and historical analysis of specific episodes, ranging from Newton’s introduction of the theory of gravity to contemporary cosmology.

]]>The formalism of quantum theory over discrete systems is extended in two significant ways. First, tensors and traceouts are generalized, so that systems can be partitioned according to almost arbitrary logical predicates. Second, quantum evolutions are generalized to act over network configurations, in such a way that nodes be allowed to merge, split and reconnect coherently in a superposition. The hereby presented mathematical framework is anchored on solid grounds through numerous lemmas. Indeed, one might have feared that the familiar interrelations between the notions of unitarity, complete positivity, trace-preservation, non-signalling causality, locality and localizability that are standard in quantum theory be jeopardized as the partitioning of systems becomes both logical and dynamical. Such interrelations in fact carry through.
