Wave Equations on Curved Spacetimes
… predictability more generally for subluminal and superluminal Lorentz- invariant scalar wave equations. We study the Born-Infeld scalar in two dimensions, which has both a superluminal and subluminal formulation. Contrary to previous expectation, we find that, at least in some sense, the …

Quantum nonlocality: an analysis of the implications of Bell's Theorem and quantum correlations for nonlocality.
… that SEL with some provisos characterizes the No-Superluminal-Action (NSA) of the Special Theory of Relativity (STR), and he argued that SEL is not violated in EPR. Butterfield (1994) proposed that SEL (without Hellman's provisos) characterizes the lack of superluminal Lewisian causation, and he …

Slow and fast light by spectral hole-burning in the solid state
The generation of slow (subliminal) and fast (superluminal) light has attracted a great deal of attention over recent years because of potential applications in optical data storage, optical switching, quantum data processing and pulse regeneration. Slow and fast light can be achieved in materials …

Numerical modeling of nonlinear mode interaction in semiconductor lasers and amplifiers to generate slow/fast light
… (CAD). In the spectral vicinity of CAD points, superluminal group velocity is observed, which can be used for improving the sensitivity of ring laser gyros and other interferometric sensors. In this dissertation, we established possibility of superluminal behavior (-1 < ng < 1) through NLI in …

Polarization VLBI monitoring of BL lacertae - kinematics, faraday effects and intermediate scale structure
… the literature to derive a kinematic model for superluminal components (knots) in its radio jet. Four epochs of multi-frequency monitoring of BL Lac presented here demonstrate the extreme variability of this source in both total intensity and polarized flux density. A number of superluminal …

The space around BQP
… we find that these speedups may be related to superluminal signaling in these models. Surprisingly, we find one model which is only slightly more powerful than BQP. Inspired by this model, we study and resolve an open problem in classical complexity related to the power of statistical-zero …

Tensorial spacetime geometries carrying predictive, interpretable and quantizable matter dynamics
… provide the tools to calculate the rate at which superluminal particles radiate off energy to become infraluminal, as explained above. Remarkably, it is again the three geometric conditions of hyperbolicity, time-orientability and energy-distinguishability that allow the quantization of general …

Parsec-scale polarization of the jet in quasar 4C 71.07
… range of apparent velocities from stationary to superluminal. No evidence was found for variations in the polarization properties of components as they move out. One prominent component shows evidence for non-ballistic motion since its linear trajectory does not align with the core position. The …

Application of Signal Advance Technology to Electrophysiology
Medical instrumentation used in diagnosis and treatment relies on the accurate detection and processing of various physiological events and signals. While signal detection technology has improved greatly in recent years, there remain inherent delays in signal detection/ processing. These delays may …
