comment Single electron pumps, superconducting energy gap
Please, be more specific about the pumping cycle, the charge stability diagram of your pump etc.

comment What are the limits of applicability of Coulomb's Law?
QED corrections to Colombo law can be worked out analytically, at least to the first order in $\alpha $.

comment A theoretical problem on Mechanics
Welcome to Physics.SE! Anna, your question looks like a "do my homework" request. As such, it needs more work on your part to be acceptable here. Please, see our guidelines for this kind of question in the FAQ.

comment Is there any phenomenon in physics which is sensitive to irrational numbers?
Antoher example, closely related to what @Lagerbaer suggests are quasi-crystals. Again, the key word is "commensurability"

comment Does the collapse of the wave function increase entropy of the atomic system itself?
And if you do postselection instead of a trace (ie detect and measure the photon) you can prepare a pure state with $ S=0 $

comment Does the collapse of the wave function increase entropy of the atomic system itself?
It does. W.f. collapse means that you've made a measurement so the environment (e.g an emitted photon) has info about the internal state. Tracing out the environment leaves the atom in an entropyful mixed state

This really nails it! Thanks to you both for a quick and decisive resolution.
