Bubble nucleation rate in fourth-order gravity.

We calculate the bubble nucleation rate in a fourth-order gravity theory whose action contains an R term, under the thin-wall approximation, by two different methods. First the bounce solution is found for the Euclidean version of the original action. Next, we use a conformal transformation to transform the theory into general relativity with an additional scalar field and then proceed to find ...

How to Calculate the Bubble Nucleation Rate in First Order Transitions Non-perturbatively

Electroweak baryogenesis in the Standard Model (or extensions of it) happens on or near the surface of the bubbles which nucleate and subsequently grow during the first order Electroweak phase transition. In this case, it is very difficult to compute the bubble nucleation rate analytically with sufficient accuracy: since the transition is radiatively generated, no classical bubble solution exis...

Bubble-Nucleation Rates for Radiatively Induced First-Order Phase Transitions

We present a consistent calculation of bubble-nucleation rates in theories of two scalar fields. Our approach is based on the notion of a coarse-grained free energy that incorporates the effects of fluctuations with momenta above a given scale k. We establish the reliability of the method for a variety of two-scalar models and confirm the conclusions of previous studies in one-field theories: L...

Electroweak Bubble Nucleation , Nonperturbatively

We present a lattice method to compute bubble nucleation rates at radiatively induced first order phase transitions, in high temperature, weakly coupled field theories, nonperturbatively. A generalization of Langer’s approach, it makes no recourse to saddle point expansions and includes completely the dynamical prefactor. We test the technique by applying it to the electroweak phase transition ...

Surface bubble nucleation stability.

Recent research has revealed several different techniques for nanoscopic gas nucleation on submerged surfaces, with findings seemingly in contradiction with each other. In response to this, we have systematically investigated the occurrence of surface nanobubbles on a hydrophobized silicon substrate for various different liquid temperatures and gas concentrations, which we controlled independen...
