Jiang-Min Zhang

This really depends on the atom and the geometry of the trap. But i guess it is on the of order of 5 seconds or even longer.

Muhammad Ayub

Thanks dear Zhang. Could you provide any reference?

Rabiu Musah

This is actually a problem for Cold Atoms (Molecules) trapped in Optical Lattices of any geometry. Cold atom condensates are only stable for short times. Typically ms. Also with respect to what Zhang said, you need to know the type of atoms (molecules) involved. Some people connect the Coherent Time, tau to this stability issues and so define tau = pi/Omega [arXiv:1206.5023v1]. For NaK, this yields 100 ms.
