Frozen Rydberg gas and ultra-cold plasmas
Obtained by laser excitation, Rydberg atoms are atoms whose one valence electron is on a very excited orbit corresponding to a high principal quantum number n (n>20). Such an atom has a "huge size", n2 times the hydrogen atom in the fundamental state. Such "giant atoms" are very sensitive to any kind of perturbation. One likes often to compare the properties of the Rydberg atoms with those of the "ordinary atoms" which would be found in "extreme situations". The excitation of a cold atomic (...)
