Cooling Mechanics:
Laser cooling decelerates thermal atoms to ~1 µK. Lowering the evaporative trap wall releases high-energy atoms, plunging remaining cloud temperature below the critical threshold Tc = 280 nK.

Quantum State Summary:
At T = 45 nK (< Tc = 280 nK), over 88% of Rubidium-87 atoms occupy the single zero-point harmonic ground state, merging into a macroscopic quantum wave packet with spatial phase coherence.
