Remember quantum mechanics? Due to the heisenberg uncertainty principle, you can never bring particles (like electrons) to absolute rest, like you might think would happen at absolute zero. The minimum energy would be (1/2)hf, where h is planck's constant and f is the oscillation frequency associated with the De Broglie wavelength of the electron. This would be the zero-point energy, and does prevent liquid helium from freezing... at least below a pressure of 25 atms.
