“…3 Henceforth, we use natural units in which the conventional velocity of light c = 1. 4 We note that a Fermi all-sky variability analysis reported significant brightening of TXS 0506+056 in the GeV band some five months previous to the observation of IceCube-170922A [8]. A conservative approach would be to allow for a time difference of 150 days between the photon and neutrino propagation times, which would relax our bound on ∆v νγ by a factor 15.…”

Limits on neutrino Lorentz violation from multimessenger observations of TXS 0506+056

et al. 2019

The observation by the IceCube Collaboration of a high-energy (E 200 TeV) neutrino from the direction of the blazar TXS 0506+056 and the coincident observations of enhanced γ-ray emissions from the same object by MAGIC and other experiments can be used to set stringent constraints on Lorentz violation in the propagation of neutrinos that is linear in the neutrino energy: ∆v = −E/M 1 , where ∆v is the deviation from the velocity of light, and M 1is an unknown high energy scale to be constrained by experiment. Allowing for a difference in neutrino and photon propagation times of ∼ 10 days, we find that M 1 3 × 10 16 GeV. This improves on previous limits on linear Lorentz violation in neutrino propagation by many orders of magnitude, and the same is true for quadratic Lorentz violation.

We derive some of the most stringent constraints on neutrino speed, weak equivalence principle violation, Lorentz invariance violation, and dual lensing from the first high-energy astrophysical neutrino source: TXS 0506+056. Observation of neutrino (IceCube-170922A) and photons in a similar time frame and from the same direction is used to derive these limits. All of these constraints are stronger than those obtained from the observation of SN 1987A. We describe ways in which these constraints can be further improved by orders of magnitude.

“…Many modern-day technologies rely on the ability to do this accurately and precisely, including navigation [1], telecommunication systems [2], electrical power grids [3], and even electronic transactions on the stock exchange [4]. The most advanced timekeeping can be applied to fundamental science studies [5], such as searches for dark matter [6] and neutrino speed-measurements [7].…”

Optical-Clock-Based Time Scale

et al. 2019

A time scale is a procedure for accurately and continuously marking the passage of time. It is exemplified by Coordinated Universal Time (UTC), and provides the backbone for critical navigation tools such as the Global Positioning System (GPS). Present time scales employ microwave atomic clocks, whose attributes can be combined and averaged in a manner such that the composite is more stable, accurate, and reliable than the output of any individual clock. Over the past decade, clocks operating at optical frequencies have been introduced which are orders of magnitude more stable than any microwave clock. However, in spite of their great potential, these optical clocks cannot be operated continuously, which makes their use in a time scale problematic. In this paper, we report the development of a hybrid microwave-optical time scale, which only requires the optical clock to run intermittently while relying upon the ensemble of microwave clocks to serve as the flywheel oscillator. The benefit of using clock ensemble as the flywheel oscillator, instead of a single clock, can be understood by the Dick-effect limit. This time scale demonstrates for the first time sub-nanosecond accuracy for a few months, attaining a fractional frequency stability of 1.45×10 −16 at 30 days and reaching the 10 −17 decade at 50 days, with respect to UTC. This time scale significantly improves the accuracy in timekeeping and could change the existing time-scale architectures.
