Rev. Lett. 84, 5687 (2000)] of a balance between electromagnetically induced $1/r$ attraction and a short-range interatomic repulsion. The corresponding frequencies for monopole, dipole, and quadrupole modes are calculated numerically in the zero temperature case.5 pages, Latex. The boundary conditions for the l=0 mode improved. The values of eigenfrequencies for the l=0 and l=2 modes corrected. The final sentences correctedStatistical Mechanicstext
