Example? The classic example is Tunneling. From the article: Here ,LRε are the energies of the modes in the absence of the tunneling coupling Jand γis the linewidth in the linear regime. The nonresonant excitation enters the polariton dynamics through the stimulated relaxation rate ()2RRn. The exciton reservoir density consists of the active excitons that fulfill energy and momentum conservation for scattering into the lower polariton branch.... At high excitation intensity, the growth rate is much larger than the tunneling between the two wellsand the Josephson currents can be neglected during the exponential growth stage of the condensate formation. This implies that the initial randomness of the relative phase does not affect the density dynamics that is therefore deterministic up to small fluctuations.... Finally, our two-mode model also allows us to understand the role of the polariton-polariton interactions on the Josephson oscillations. In the absence of interactions, the oscillation frequency is set by the detuning and tunneling coupling....

What exactly isn’t conserved in tunneling? There’s no shortage of, or extra, energy, charge, momentum, or anything else, after than there was before, the tunneling happened. For example, particles can’t tunnel into places they don’t have enough energy to occupy. So what am I missing?

and just because you have an oscillator means nothing additional. we will see what and where this may lead but right now I can only say okay so what?
