Do neutrinos experience tunneling, and thus we think they have no mass yet they do because they are tunneling?

Not really.

Neutrinos are a highly relativistic particle, so the proper treatment involves QFT. Tunneling in QFT is rather subtle and not very apparent, and only really emerges in more of a quantum mechanics setting.

The way they acquire mass is not understood well, and there are many proposals for exactly how they might gain (the very small) mass.

My personal opinion, follows more along the lines of an SO(10) GUT theory seesaw mechanism.

Could you say something about neutrino oscillation?

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...
