← ScienceWhich consequence resultswhen the laser cooling limit exceeded?
A)Atoms reach motional ground state
B)Quantum degeneracy becomes prominent
C)Bose-Einstein condensation occurs instantly
D)Collisional heating becomes significant✓
💡 Explanation
When standard Doppler laser cooling is pushed past its theoretical limit, the **Sisyphus cooling** mechanism contributes significant heating effect; therefore, collisional heating prevails rather than the cooling limit approaching absolute zero, because recoil limit and light polarization gradients are relevant instead.
