Dark Energy and Condensate Stars: Casimir Energy in the Large
Pawel O. Mazur, Emil Mottola
Vacuum fluctuations and the Casimir effect are considered in a cosmological setting. It is suggested that the dark energy, which recent observations suggest make up 73% of our univ…
Linear Response and the Validity of the Semi-Classical Approximation in Gravity
Paul R. Anderson, Carmen Molina-Paris, Emil Mottola
We propose a quantitative test for the validity of the semi-classical approximation in gravity, namely that the solutions to the semi-classical equations should be stable to linear…
Comment on "Nongaussian Isocurvature Perturbations from Inflation"
Ignatios Antoniadis, Pawel O. Mazur, Emil Mottola
In a recent paper of Linde and Mukhanov, a hybrid inflationary model with nongaussian density perturbations and a ``blue'' spectral index n > 1 was presented. In this comment we po…
Comment on "Gravitationally Induced Neutrino-Oscillation Phases"
Tanmoy Bhattacharya, Salman Habib, Emil Mottola
We critically examine the recent claim (gr-qc/9603008) of a ``new effect'' of gravitationally induced quantum mechanical phases in neutrino oscillations. A straightforward exercise…
Finite Energy Instantons in the O(3) Non-Linear Sigma Model
Peter G. Tinyakov, Emil Mottola, Salman Habib
We consider winding number transitions in the two dimensional O(3) non-linear sigma model, modified by a suitable conformal symmetry breaking term. We discuss the general propertie…
