The Cosmic Coincidence Problem in the Brane World
Massimo Pietroni
The so called `cosmic coincidence' problem seems to suggest a coupling between dark energy and dark matter. A possibility could be given by dark matter particles with masses depend…
Are Heavy Particles Boltzmann Suppressed?
P. Bucci, M. Pietroni
Matsumoto and Yoshimura have recently argued that the number density of heavy particles in a thermal bath is not necessarily Boltzmann-suppressed for T<<M, as power law corrections…
Critical Slowing Down and Defect Formation
Massimo Pietroni
The formation of topological defects in a second order phase transition in the early universe is an out-of-equilibrium process. Condensed matter experiments seem to support Zurek's…
Gauge-Invariant Renormalization Group at Finite Temperature and Debye Screening
Massimo Pietroni
I describe an application of Wilson Renormalization group to the real time formalism of finite temperature field theory. The approach has two nice features: 1) the RG flow equation…
