Weak values from path integrals

Weak values from path integrals

We connect the weak measurements framework transpharm online shopping to the path integral formulation of quantum mechanics.We show how Feynman propagators can in principle be experimentally inferred from weak value measurements.We also obtain expressions for weak values parsing unambiguously the quantum and the classical aspects of weak couplings between a system and a probe.

These expressions are shown to be useful in quantum-chaos-related studies (an illustration involving quantum scars is given), and also in solving current weak-value-related controversies (we discuss the existence of discontinuous click here trajectories in interferometers and the issue of anomalous weak values in the classical limit).
