Phase conversion in a weakly first-order quark-hadron transition
A. Bessa, E. S. Fraga, B. W. Mintz
We investigate the process of phase conversion in a thermally-driven {\it weakly} first-order quark-hadron transition. This scenario is physically appealing even if the nature of t…
On the nucleation of hadronic domains in the quark-hadron transition
B. W. Mintz, A. Bessa, E. S. Fraga
We present numerical results on bubble profiles, nucleation rates and time evolution for a weakly first-order quark-hadron phase transition in different expansion scenarios. We con…
Semiclassical calculation of decay rates
A. Bessa, C. A. A. de Carvalho, E. S. Fraga
Several relevant aspects of quantum-field processes can be well described by semiclassical methods. In particular, the knowledge of non-trivial classical solutions of the field equ…
Quasiparticle model for deconfined matter and the nucleation of hadrons
A. Bessa, E. S. Fraga
Assuming a first-order chiral transition scenario, we study the process of phase conversion driven by homogeneous nucleation. We adopt a quasiparticle model whose parameters are fi…
Correlations around an interface
A. Bessa, C. A. A. de Carvalho, E. S. Fraga
We compute one-loop correlation functions for the fluctuations of an interface using a field theory model. We obtain them from Feynman diagrams drawn with a propagator which is the…
