Phys. Rev. Lett. 69, 2743–2746 (1992)Instability and subsequent evolution of electroweak bubblesReceived 4 August 1992; published in the issue dated 9 November 1992 Bubbles in a first-order electroweak phase transition are nucleated with radii R0 and expand with velocity v. If v is subsonic, a bubble becomes unstable to nonspherical perturbations when its radius is roughly 104R0. These perturbations acclerate the transition, and the effective velocity of bubble growth rapidly becomes supersonic. The transition should subsequently proceed spherically via detonation. If for some reason the onset of detonation is postponed, the surface area of the bubbles may be enhanced by 105. We discuss consequences for electroweak baryogenesis. © 1992 The American Physical Society URL:
