I'm a PhD student at the CDT in Controlled Quantum Dynamics at Imperial College London. My research is on strong-field and ultrafast physics, and I mostly study tunnel ionization and high-harmonic generation.

Check out my papers - they're nice!

You can also check out my Master's dissertation, "Under-the-barrier electron-ion interactions during tunnel ionization" at arXiv:1307.7329 or on my CDT homepage.

I did my Bachelor's degree in Physics in Mexico at the Faculty of Science at the Universidad Nacional Autónoma de México (UNAM). I studied quantum optics for my dissertation, and I have some nice results on the Jordan-block structure of the annihilation operator. You can find it (in Spanish) in the UNAM thesis repository.

comment J-coupling constants and nuclei with zero total angular momentum
There is no requirement that, as you add nucleons to a potential well, they will pair up neatly and leave spin zero. It doesn't happen to electrons in atoms, either (this is known as Hund's rules, and in fact electrons will try and maximize their spin in many cases). Why would you expect it to hold in nuclei?

comment Is it possible that we have a physical state which is a mixture of discrete eigenstates and continuous ones?
No, that is not the case. The experiment is indeed done on macroscopic samples, but all the atoms that contribute have the exact same quantum state. By 'population' here I mean $|\psi|^2$, i.e. a fraction of the wavefunction of a single atom. If you simply assume only a fraction of the atoms has been ionized, you will fail to get all the physics. (In particular, that decohered sample would not display HHG or ATI rings.) Do read the papers - if they are unclear I can probably suggest better references but I need to know what you're having trouble with.

comment Safety glasses for a CO₂ laser
I'm not sure that this does address the question. The OP is trying to build a laser from scratch, pretty much, so that within their project "normal" use includes manipulation of optical elements directly in contact with the beam. Discussing safety measure A while completely ignoring safety measure B where the latter is essential is, at the least, misleading, I'm afraid.
