← ScienceWhich risk increases when laser cooling brings rubidium to Bose-Einstein condensate?
A)Spontaneous parametric down-conversion occurs
B)Increased three-body recombination rates✓
C)Increased thermal conductivity observed
D)Material cold welding is initiated
💡 Explanation
Increased three-body recombination occurs because BEC formation brings rubidium atoms very close together. This increases the chance of three atoms colliding, leading to release of energy and loss of atoms, therefore BEC lifetime is limited rather than enabling other quantum processes.
