Bubble Wall Velocity in the MSSM

We compute the wall velocity in the MSSM with W , tops and stops contributing to the friction. In a wide range of parameters including those which fulfil the requirements of baryogenesis we find a wall velocity of order vw ≈ 10 −2 much below the SM value. 1 Bubble Wall Equation of Motion in the MSSM Energy conservation leads to the equations of motion of an electroweak bubble wall interacting w...

Gas bubble dynamics in soft materials.

Epstein and Plesset's seminal work on the rate of gas bubble dissolution and growth in a simple liquid is generalized to render it applicable to a gas bubble embedded in a soft elastic solid. Both the underlying diffusion equation and the expression for the gas bubble pressure were modified to allow for the non-zero shear modulus of the medium. The extension of the diffusion equation results in...

Quantum Oscillations of the Nanoscale Structural Inhomogeneities of the Domain Wall in Magnetic Bubble

It is shown that at low temperatures, quantum oscillations of nanoscale structural inhomogeneities (the vertical Bloch line and the Bloch point) occur in the domain walls of cylindrical magnetic domains formed in a uniaxial magnetic film with strong magnetic anisotropy. The conditions for the excitation of these oscillations are determined.

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 ...
