Suppression of capillary instability in a confined quantum liquid filament
The study investigated capillary instability in a quantum Bose-Bose mixture forming an elongated filament confined within an optical waveguide. While the system exhibited instability in free space, increasing transverse harmonic confinement progressively suppressed this effect. The research demonstrated that stabilization is complete beyond a critical trap frequency, confirming that confinement effectively suppresses the capillary breakup predicted by classical fluid models.
