Summary

The probability density of two Bose-Einstein condensates is deterministic yet unpredictable, exhibiting chaotic behavior. Adjusting initial conditions can control this chaos, preventing nonphysical outcomes and promoting stable oscillations.

Main Results:

  • The probability density of two coupled BECs is shown to be deterministic but unpredictable.
  • Numerical calculations confirm the analytical findings of chaotic probability density.
  • Nonphysical implosions and unboundedness were observed in the time evolution.

Conclusions:

  • The interplay between quantum wave functions and classical chaos leads to deterministic unpredictability in BECs.
  • Chaotic dynamics in BECs can manifest as nonphysical phenomena.
  • Initial condition manipulation offers a viable strategy to control and stabilize BEC dynamics.
