Analysis in the space of observables

    Activity: Talk or presentationInvited talkscience-to-science

    Description

    Unbounded self-adjoint operators play the role of the real numbers in quantum mechanics, normal operators that of complex ones. Key tools of theoretical physicists in this context are distributions with values in the space of observables (quantum field theory) and analytic functions therein (perturbation methods). Despite this fact the literature provides no rigorous definition of these concepts or (at best) woefully inadequate ones. In our talk we present a theoretical basis for a rigorous approach to spaces of observable-valued tempered distributions and holomorphic functions. We show how the regular toolbox of theoretical physics (Fourier transform, Hermite expansions, McLaurin series) carries over to this situation and use this to display some non-trivial examples.
