  • Coarse-grained distinguishability of field interactions 
    Bény, Cédric (Wien : Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2018)
    Information-theoretical quantities such as statistical distinguishability typically result from optimisations over all conceivable observables. Physical theories, however, are not generally considered valid for all ...
  • The renormalization group via statistical inference 
    Beny, Cedric; Osborne, Tobias J. (Bristol : IOP Publishing Ltd., 2015-08-05)
    In physics, one attempts to infer the rules governing a system given only the results of imperfect measurements. Hence, microscopic theories may be effectively indistinguishable experimentally. We develop an operationally ...
