Bubble Wall Dynamics at Finite Temperature {
نویسنده
چکیده
Cosmological phase transitions may have played important roles in shaping the present Universe. If the transition is of the rst order, it proceeds with the nucleation of new-phase bubbles and their growth. The details of the bubble dynamics can aaect the consequencies of the phase transition. For example, baryogenesis in the course of the electroweak phase transition is known to depend on the bubble-wall velocity. In this work, starting with the eeective action that is obtained by making use of the real-time formalism in the nite temperature eld theory, we examine how the dynamics of the bubble wall can be investigated.

متن کاملHow fast can the wall move? A study of the electroweak phase transition dynamics.
We consider the dynamics of bubble growth in the Minimal Standard Model at the electroweak phase transition and determine the shape and the velocity of the phase boundary, or bubble wall. We show that in the semi-classical approximation the friction on the wall arises from the deviation of massive particle populations from thermal equilibrium. We treat these with Boltzmann equations in a fluid ...

A Lagrangian-Eulerian numerical scheme for the investigation of bubble motion in turbulent flow is developed. The flow is analyzed in the Eulerian reference frame while the bubble motion is simulated in the Lagrangian one. Finite volume scheme is used, and SIMPLEC algorithm is utilized for the pressure and velocity linkage. The Reynolds stresses are modeled by the RSTM model of Launder. Upwind ...
متن کاملNumerical Analysis of Temperature Fields inside Nonspherical Bubbles in the Final Stage of Collapse
The temperature fields inside a collapsing bubble near a plane rigid wall are investigated. We develop a numerical method based on the boundary element method combined with the finite volume method. In this method, the adaptive unstructured grids which are generated by Delaunay triangulation are used inside the largely deformable bubble to consider the heat transfer of the internal gas. We comp...
