- TL;DR Summary
- How are Lagrangian mechanics --which posit a continuous particle path-- integrated within the framework of QFT if continuity of a particle's movement is not established/addressed in QM.
In the following thread:
https://www.physicsforums.com/threads/particle-movement-in-quantum-mechanics.1054807/
the discussion established/confirmed that the matter of a particle’s continuity of movement in Quantum Mechanics QM is not a scientific question in QM, refer to PeroK post # 6:
“Orthodox QM goes further than that. Asking what a particle does between measurements makes no sense as a scientific question. For example, only measurements of position make sense. Asking where a particle was when you didn't measure its position is not a scientific question.”
How is the foregoing reconciled with the application of Lagrangian mechanics in Quantum Field Theory which ––if I understand correctly–– posits continuous particle movement?
