In the lab frame youngs slits are easy to understand once you associate a de Brogle wavelength to the particle. I wonder if anyone has a manner to visualise/understand youngs slit interference in the frame of the particle i.e. one where its wavelength is infinte.
 
Physics news on Phys.org
You assign a probability wave to the particle using the debroglie wavelength. It is not recommended that you follow the particle through its path. Because there is no way you can know its exact position and the path it takes.
 
Ahh FZ+, is it the particle that is moving or is it the slit and the laboratory that moves around the particle?
Surely you can visualise the same scenario in which you are a particle at rest, and a double slit is approaching you.
 

Thread 'Schrödinger equation and classical wave equation'

Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Thread 'Is Maxwell's electromagnetism an effective (field) theory?'

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
