A universal formula for dispersion coefficients between alkali atoms
A universal formula is developed for dispersion coefficients between alkali atoms. It gives values for C2n for n = 3, 4, 5 and depends only on the static multipole polarizabilities and the correspondi...

It is shown that repulsive interactions between larger "hard squares" and smaller "point particles" in a mixed adlayer model modify the hard-square order–disorder transition and can produce phase separation. ©2001 American Institute of Physics.
