Solving a classical problem using quantum physics

I came across a discussion on net recently, where projectile motion was solved using the quantum mechanical approach.
[PLAIN]http://www.physics.csbsju.edu/QM/fall.14.html[/PLAIN]
I have already seen solution of the vibrations in string using quantum mechanics.
I want to ask can i use quantum mechanics to find the vibrations in ring. if there is any text on this stuff available, please let me know. Need a little guidance before starting the rigorous calculation process.
Thank you

Wouldn't it be exactly the same as for the string except with continuous boundary conditions on the edge.

sorry i forgot to mention. By ring it meant a solid ring, whose vibration analysis will require the knowledge of solid mechanics. So now you see nature of problem differs entirely.
 
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...
