Collisional avalanches significantly increase atom loss in ultracold gases. Exceeding a critical collisional opacity enhances inelastic collisions, questioning the hydrodynamic regime in Bose-Einstein condensation experiments.

Area of Science:

  • Atomic, Molecular, and Optical Physics
  • Quantum Gases

Background:

  • Bose-Einstein condensates (BECs) are ultracold quantum states of matter.
  • Understanding atom loss mechanisms is crucial for BEC stability and research.

Purpose of the Study:

  • To investigate the role of collisional avalanches in atom loss in ultracold gases.
  • To identify the critical conditions for enhanced inelastic collisions.

Main Methods:

  • Experimental observation of a large (87)Rb condensate.
  • Analysis of atom loss rates and collisional properties.

Main Results:

  • Collisional avalanches cause an 8-fold increase in the initial loss rate.
  • A critical value for collisional opacity was identified.

Related Experiment Videos

  • Losses due to inelastic collisions are substantially enhanced above this critical value.

    • Conclusions:

    • Collisional avalanches are a significant loss mechanism in ultracold gases.
    • The existence of a critical collisional opacity challenges the attainment of the hydrodynamic regime in conventional BEC experiments.
