Guendelman Eduardo : Vacuum Energy and Child Universes

In particle physics, spontaneous breaking of scale invariance (SSB of SI) is applied to mechanisms for confinement of quarks and gluons, while in gravity and cosmology it relates to the acceleration of the present universe, quintessence scenarios and inflation of early universe. In gravity and cosmology, SSB of SI is nicely implemented in the context of the Two Measures Theory, which I have developed with Alex Kaganovich. This model addresses all the cosmological questions mentioned before and also provides an interesting solution to the 5th force problem that most quintessence scenarios suffer. I have also been studying the possibility of creating a universe in the laboratory starting from a bubble of false vacuum (see figure).

In particular, with Jacob Portnoy, I have considered the creation of a universe from a stable particle like configuration and with Idan Shilon, I study the gravitational trapping of particles by these stabilized particle like configurations.
