Current of fermions scattered off a bubble wall.

Proceeding from WKB quantization conditions, we derive a semiclassical expression for the current of fermions scattered off a propagating bubble wall in the presence of longitudinal gauge field. It agrees with the expression used by Nasser and Turok in semiclassical analysis of instability of electroweak bubble walls with respect to longitudinal Z condensation. We discuss the resulting dispersi...

Fermion scattering off a CP-violating electroweak bubble wall.

A general prescription to solve the Dirac equation in the presence of CPviolating electroweak bubble wall is presented. The profile of the bubble wall is not specified except that the wall height is m0 and zero deep in the brokenand the symmetric-phase regions, respectively, where m0 is a fermion mass given by the Higgs-vacuum-expectation value and the Yukawa coupling. The CP-violating effects ...

Fermion Scattering off a CP-violating Bubble Wall in the Background of a Uniform Magnetic Field

In the scenario of the electroweak baryogenesis we consider the dynamics of fermions with a spatially varying mass in presence of a CP-violating bubble wall and a uniform magnetic field perpendicular to the wall. The relevant quantity for baryogenesis, RR→L − RL→R , is studied (RR→L and RL→R being the reflection coefficients for right-handed and left-handed chiral fermions, respectively). PACS ...

The Role of Fermions in Bubble Nucleation

We present a study of the role of fermions in the decay of metastable states of a scalar field via bubble nucleation. We analyze both one and threedimensional systems by using a gradient expansion for the calculation of the fermionic determinant. The results of the one-dimensional case are compared to the exact results of previous work.

Giant bubble pinch-off.

Self-similarity has been the paradigmatic picture for the pinch-off of a drop. Here we will show through high-speed imaging and boundary integral simulations that the inverse problem, the pinch-off of an air bubble in water, is not self-similar in a strict sense: A disk is quickly pulled through a water surface, leading to a giant, cylindrical void which after collapse creates an upward and a d...
