WebMay 31, 2024 · Feynman paths (resp. fields) form an ensemble only in imaginary time QM (resp. Euclidean QFT), since only there one has a meaningful (i.e., positive) measure. In real time QM the Feynman measure is well-defined but complex, but one cannot associate stochastic processes (hence ensembles) to complex measures. shoe spot coimbatoreWebIn the second lecture, Feynman looks at the different paths a photon can take as it travels from one point to another and how this affects phenomena like reflection and diffraction. 3.
