    Perhaps you're not aware that not only can the USA not trade with Cuba under the embargo, but any international vessel that trades with Cuba cannot trade with the USA on that same trip.

When I (a US citizen) went we brought tens of thousands of dollars worth of medicines that US hospitals were disposing because they were just past their expiration date (but still good for all intents and purposes). The hospitals we visited were extremely gracious for this, medicines are really in short supply there because of the embargo.

    You may like not dealing with Americans travelling in your little vacation paradise, but most cities are poorly lit, with only every 3 or 4 streetlights on. I thought at first this was to save electricity, but it's because they have a very short supply of light bulbs they can get through the embargo.

    You may love the antique cars still driving around (with ridiculous amounts of air pollution), but Cubans have tough times getting automobile parts through the embargo. That's why they still have many old cars from before the embargo was placed. They have tough times not only buying new cars but even replacement parts for old cars.

  19. Re:DIY? on Nanotechnology + Superconductivity = Spintronics · · Score: 3, Informative
    Electron spin is NOT the same phenomenon as orientation of magnetic field. But you can think of it the following way. An electron is a tiny magnetic dipole. The potential energy of a dipole in a magnetic field is the inner product -mu dot B. Where mu is the dipole moment (Bohr Magneton in the case of an electron), B is the magnetic field. The dipole wants to go to the lowest energy state, which is aligned with the field (negative energy).

    Quantum mechanics forces a measure of the electron's spin (and hence the direction of the dipole moment) into one of the allowable eigenstates. For a spin-1/2 fermion, such as an electron, there are only two states.

    now - if you apply a field in the z direction and measure the spin in the z direction, there is a definite preference for the spin to align with the field.

    if you apply the field in the y direction and measure in the z direction, then both states are of equal energies and there is no preference.

    If you turn on interactions between electrons, like ferromagnetic or anti-ferromagnetic coupling, you get interesting effects, esecially at points where there the electron-electron interaction is countered by the field, and you have phase transitions at that point. if you allow for different couplings, different field directions, you can build up very rich phase diagrams of such systems, which are actually being studied by top physicists today.

    Eg - anti-ferromagnetic interactions (neighbors want to be anti-aligned) on a triangle lattice is a frustrated magnet. A spin will be up, another neighbor will be down, the third is equally frustrated and doesn't know where to go. This makes very degenerate ground states, which have interesting properties.

    Okay, if you want to get technical you have to look at the Hamiltonian of the problem, to see the change of energy would be to flip a single spin.

    Free electrons means without any other interactions, and spin up and spin down have no preference. In fact, the directions up/down don't mean anything unless some non-isotropic disturbance is present in the system. This would usually be the applied magnetic field.

    If you have a ferromagnet, the electrons want to align parallel, so flipping one electron costs energy. This energy can come from thermal excitations, so to get the fully aligned state you need to cool the system down to minimize these excitations.

    As for your battery, remember you are fundamentally storing chemical potential to drive current (actually, I'm kind of BSing here, so maybe a chemist can correct this), so aligning the spins probably won't do much. In fact, you'd most likely waste 100x or more of the energy the battery would provide just running the fridges necessary to align the spins.

    But like I said, you'd really need a spintronic battery, which maybe some scientists are studying somewhere. A standard battery would lose the spin coherence relativly quickly, even if you charged it with a fully spin-polarized current.

    Now about your question, if you put the spins all in spin-down state and put an up-pointing magnetic field, that's alot of energy stored there (assuming no other interactions between the spins that would allow this). But that would be very difficult to set up a state like this.

    Actually such a state, if you did set it up, is at a negative temperature, believe it or not. Basically meaning there is a population inverions, with more excited states populated than ground states, and is a process fundamental to laser operation.
