About

Peter Warwick Morgan is a Lab Associate in the Physics Department at Yale University, where his work centers on the foundations of physics and the long-standing question of how classical and quantum mechanics relate to one another. A British citizen educated at Oxford and Durham, he brings a distinctly purist sensibility to problems at the conceptual core of physical theory.

His research advances a dataset and signal-analysis interpretation of quantum mechanics and quantum field theory, drawing on Koopman's Hilbert-space formalism for classical mechanics and moving carefully between discrete, micro-level descriptions and integral, macro-level ones. Recurring themes in his published work include the equivalence of random fields and quantum fields, Bell inequalities for random fields, the collapse of a quantum state understood as a joint probability construction, and a signal reanalysis of renormalization. His papers have appeared in journals including the Journal of Physics A, Annals of Physics, Physica Scripta, and EPL, and he has been invited to speak at venues including Yale and Oxford's Philosophy of Physics seminar.

This commitment to conceptual rigor and clear interpretation of the mathematics underlying modern physics aligns with the SMART America Institute's mission to advance the responsible and well-founded development of emerging technologies, including quantum science, in the public interest.
