Dimitri is a high energy theoretical physicist and string theorist.
As of Oct 2017 he is a postdoctoral research fellow at the Max-Planck Institute for Physics (MPI) in Munich. He is also an associate member of the Arnold Sommerfeld Center for Theoretical Physics at Ludwig-Maximilians-Universitat (LMU) in Munich. He earned his DPhil at the University of Sussex in 2011 and has previously held postdoctoral research positions at the University of Nottingham and King's College London.
Despite huge progress underway in unravelling the question 'What is String Theory?', a fully satisfactory non-perturbative formulation (or definition) of String Theory has yet to be discovered. Although partial answers are available, such as AdS/CFT, BFSS Matrix Model and String Field Theory, there are indications that the final answer is lacking. A central underlying focus of my research is to understand how to define String Theory non-perturbatively. Fundamental requirements for a satisfactory answer is that it be independent of compactification and background, and that it reproduce Superstring Perturbation Theory in appropriate limits.
A related smaller question is: 'What is Quantum Gravity?'. Gravity is the least well understood force of nature, being famous for its (at least perturbative) incompatibility with the laws of quantum mechanics. Since String Theory is a theory of quantum gravity we can ask 'what aspects of classical gravity emerge out of quantum superstring theory and what aspects do not?'. Here there is the notion of a coherent state that will likely play a fundamental role: very generally, coherent states enable one to study the emergence of classicality out of quantum mechanics. This should therefore also be true in string theory, where in particular the corresponding coherent states are inherently non-perturbative and non-local from a spacetime viewpoint.
Together with Gia Dvali and Dieter Luest at MPI, I am conducting a large and detailed in-depth study of coherent states in string theory and quantum field theory. Some of the key questions of current interest are:
