In time-of-flight positron emission tomography (TOF-PET), the timing capabilities of scintillation-based detector play an important role. An approach for fast is using so-called metascintillators, which combine two materials leading to synergistic blending their favorable characteristics. added effect BGO-based metascintillators taking advantage better transportation Cherenkov photons through U...

We present a number of arguments to demonstrate that a quantum analog of the Cherenkov effect occurs when two nondi...

We study, numerically, the influence of third-order dispersion (TOD) on modulation instability (MI) in optical fibers described by the extended nonlinear Schrödinger equation. We consider two MI scenarios. One starts with a continuous wave (CW) with a small amount of white noise, while the second one starts with CW with a small harmonic perturbation at the highest value of the growth rate. In e...
