Webinar: Time Operator from Parametrization Invariance and Implications for Cosmology, Prof Nikolaos Dimakis (University of the Frontier, Chile)
ABSTRACT In this talk we review the basic symmetries of parameterization invariant systems that describe the motion of particles in curved spacetimes. Motivated by the analogy of such systems to cosmological Lagrangians, we attempt to address the problem of time in quantum cosmology. To this end, we introduce a time operator which is canonically conjugate …
