We derived a three-body contact potential for Bose gases. This allows quantitative studies linking few-body collisions to condensate stability, crucial for understanding attractive forces.

Area of Science:

  • Quantum physics
  • Condensed matter physics
  • Atomic physics

Background:

  • Dilute Bose gases are quantum systems with complex interactions.
  • Understanding three-body interactions is key to Bose-Einstein condensate stability.
  • Microscopic theory provides a foundation for describing these interactions.

Purpose of the Study:

  • To derive the explicit three-body contact potential for dilute Bose gases.
  • To connect few-body collision properties to macroscopic condensate behavior.
  • To enable quantitative investigations of condensate stability with attractive forces.

Main Methods:

  • Derivation from microscopic theory.
  • Determination of the three-body coupling constant.
  • Relating the constant to vacuum two- and three-body collision amplitudes.

Main Results:

  • An explicit three-body contact potential was derived.
  • The three-body coupling constant follows the form predicted by Wu.
  • The constant is expressed in terms of fundamental collision amplitudes.

Conclusions:

  • The derived potential provides a quantitative tool for studying Bose gases.
  • This work establishes a link between microscopic collisions and condensate properties.
  • The findings are essential for understanding the stability of condensates with attractive interactions.
