Gravitational Trapping Near Domain Walls and Stable Solitons
Eduardo Guendelman, Idan Shilon
In this work, the behavior of test particles near a domain wall of a stable false vacuum bubble is studied. It is shown that matter is naturally trapped in the vicinity of a static…
Child Universes in the Laboratory
Stefano Ansoldi, Eduardo I. Guendelman
Although cosmology is usually considered an observational science, where there is little or no space for experimentation, other approaches can (and have been) also considered. In p…
Solitons as Key Parts to Produce a Universe in the Laboratory
Stefano Ansoldi, Eduardo I. Guendelman
Cosmology is usually understood as an observational science, where experimentation plays no role. It is interesting, nevertheless, to change this perspective addressing the followi…
Fine Tuning Free Paradigm of Two Measures Theory: K-Essence, Absence of Initial Singularity of the Curvature and Inflation with Graceful Exit to Zero Cosmological Constant State
E. I. Guendelman, A. B. Kaganovich
The dilaton-gravity sector of the Two Measures Field Theory (TMT)is explored in detail in the context of cosmology. The model possesses scale invariance which is spontaneously brok…
k-Essence, Avoidance of the Weinberg's Cosmological Constant No-Go Theorem and Other Dark Energy Effects of Two Measures Field Theory
E. I. Guendelman, A. B. Kaganovich
The dilaton-gravity sector of the Two Measures Field Theory (TMT) is explored in detail in the context of cosmology. The dilaton ϕdependence of the effective Lagrangian appears onl…
Exotic Low Density Fermion States in the Two Measures Field Theory: Neutrino Dark Energy
E. I. Guendelman, A. B. Kaganovich
We study a new field theory effect in the cosmological context in the Two Measures Field Theory (TMT). TMT is an alternative gravity and matter field theory where the gravitational…
