Hi,
I have been wondering about a neutron dipole moment, though hypothetical what symmetries would it be violating, wouldn't it be Parity and Time reversal? If this were to be true, would it therefore make the statement below false and the word "inverted" would imply parity?

"T is the law of time reversal symmetry, if a particle were spinning and being filmed, then the footage were to be reversed and inverted, if the particle were perfectly symmetrical then in the reversed and inverted footage the particle would look as though it were spinning forward. If not this would prove that T-symmentry had been violated."

Sorry for asking so many questions ;)
thanks

!Yes, if a neutron dipole moment were to exist, it would violate both parity (P) and time reversal (T) symmetries. Therefore, the statement you provided would indeed be false, as the particle would not look as though it were spinning forward if P and T symmetries were violated.
 
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...

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...
