Gravitons and light cone fluctuations. II. Correlation functions.
A model of a fluctuating lightcone due to a bath of gravitons is further investigated. The flight times of photons between a source and a detector may be either longer or shorter than the light propagation time in the background classical spacetime, and will form a Gaussian distribution centered around the classical flight time. However, a pair of photons emitted in rapid succession will tend t...
متن کاملGravitons and light cone fluctuations.
Gravitons in a squeezed vacuum state, the natural result of quantum creation in the early universe or by black holes, will introduce metric fluctuations. These metric fluctuations will introduce fluctuations of the lightcone. It is shown that when the various two-point functions of a quantized field are averaged over the metric fluctuations, the lightcone singularity disappears for distinct poi...
متن کاملLight-cone divergence in twist-3 correlation functions
It is argued that the definition of the twist-3 transverse momentum dependent correlation functions must be modified if they contain light-like Wilson lines. In the framework of a simple spectator model of the nucleon we show explicitly the presence of a light-cone divergence for a specific twist-3 time-reversal odd parton density. This divergence emerges for all eight twist-3 T-odd correlators...
متن کاملLight-Cone Meson-Baryon Fluctuations and Single-Spin Asymmetries
We show that energetically favored meson-baryon fluctuations present in the light-cone wavefunction of a transversely polarized proton can account for the left-right asymmetries measured in inclusive meson production processes.
متن کاملNonequilibrium Fluctuations in Metaphase Spindles: Polarized Light Microscopy, Image Registration, and Correlation Functions
Metaphase spindles are highly dynamic, nonequilibrium, steady-state structures. We study the internal fluctuations of spindles by computing spatio-temporal correlation functions of movies obtained from quantitative polarized light microscopy. These correlation functions are only physically meaningful if corrections are made for the net motion of the spindle. We describe our image registration a...
