Vacuum Polarization Effects from Fermion Zero-Point Energy
The influence of an external electromagnetic field on the vacuum structure of a quantized Dirac field is investigated by considering the quantum corrections to classical Maxwell’s Lagrangian density induced by fluctuations of the non-perturbative vacuum. Effective Lagrangian densities for Maxwell’s theory in (3+1) and (2+1) dimensions are derived from the vacuum zero-point energy of the fermion...
متن کاملDark Energy From Vacuum Fluctuations
The nature of the dark energy (DE) is one of the most outstanding problems of physical sciences today. Numerous and often ingenious attempts have been made to explain it, with multiple new papers appearing daily, yet no model proposed so far has gained a general acceptance. Modern approaches to the problem date from the pioneering papers by Zel’dovich [1], who was first to recognize the fundame...
متن کاملReducing zero-point systematics in dark energy supernova experiments
We study the effect of filter zero-point uncertainties on future supernova dark energy missions. Fitting for calibration parameters using simultaneous analysis of all Type Ia supernova standard candles achieves a significant improvement over more traditional fit methods. This conclusion is robust under diverse experimental configurations (number of observed supernovae, maximum survey redshift, ...
متن کاملMeasurability of vacuum fluctuations and dark energy
Vacuum fluctuations of the electromagnetic field induce current fluctuations in resistively shunted Josephson junctions that are measurable in terms of a physically relevant power spectrum. In this paper we investigate under which conditions vacuum fluctuations can be gravitationally active, thus contributing to the dark energy density of the universe. Our central hypothesis is that vacuum fluc...
متن کاملIrgac2006 Dark Energy and the False Vacuum
In this talk, I will present highlights of a recent model of dark energy and dark matter in which the present universe is " trapped " in a false vacuum described by the potential of an axion-like scalar field (the acceleron) which is related to a new strong interaction gauge sector, SU (2) Z , characterized by a scale Λ Z ∼ 3 × 10 −3 eV. This false vacuum model mimicks the ΛCDM scenario. In add...
