One-loop fluctuation-dissipation formula for bubble-wall velocity.
The limiting bubble wall velocity during a first-order electroweak phase transition is of interest in scenarios for electroweak baryogenesis. Khlebnikov has recently proposed an interesting method for computing this velocity based on the fluctuation-dissipation theorem. I demonstrate that at one-loop order this method is identical to simple, earlier techniques for computing the wall velocity ba...
متن کاملBubble 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...
متن کاملVortex Dynamics, Resistivity Formula, and Fluctuation-dissipation Theorems *
We investigate the problem of forces on moving vortex in a superfluid or superconductor. The main purpose is to locate the source which leads to the contradictory results in the literature. We establish the connection between this problem to the difficult but well studied subject of resistivity formula in transport theory. The relaxation time approximation used in the force calculation via forc...
متن کاملBubble wall velocity in a first order electroweak phase transition.
We calculate the velocity and thickness of a bubble wall at the electroweak phase transition in the Minimal Standard Model. We model the wall with semiclassical equations of motion and show that friction arises from the deviation of massive particle populations from thermal equilibrium. We treat these with Boltzmann equations in a fluid approximation in the background of the wall. Our analysis ...
متن کاملFluctuation and dissipation
We review the transient version of the work and fluctuation theorem. We verify the theorem explicitly by a microscopically exact analytic calculation of the probability distribution for work or entropy production in three physical examples: the Joule experiment, the compression/expansion of a gas and the process of effusion.
