How can I track the resonance of a tuning fork through a PLL if my phase lag graph is discontinuous?

I am programming a phase-locked loop to track the resonance of a tuning fork so that the tuning fork is always on resonance. This will be used in condensed matter...

What happens to an electron-hole in a quantum dot when you irradiate it with photons?

An electron-hole is just a free electron state in a quantum system. Is this right? For example, let's say that there are 2 electrons with opposite spins in the fundamental...
