Testing Lorentz invariance violations in the tritium beta-decay anomaly [PDF]
, 2000 We consider a Lorentz non-invariant dispersion relation for the neutrino, which would produce unexpected effects with neutrinos of few eV, exactly where the tritium beta-decay anomaly is found.

Magnon-Like Dispersion Relation from M-Theory [PDF]
, 2006 We investigate classical rotating membranes in two different backgrounds. First, we obtain membrane solution in $AdS_4\times S^7$ background, analogous to the solution obtained by Hofman and Maldacena in the case of string theory.

Derivative Dispersion Relations [PDF]
Proceedings of Fourth International Winter Conference on Mathematical Methods in Physics — PoS(WC2004), 2004 We discuss some analytical and numerical aspects related to the replacement of integral dispersion relations by derivative relations and also the practical applicability of the derivative approach in the investigation of high-energy elastic hadron-hadron scattering.

Dispersion relation for hadronic light-by-light scattering
EPJ Web of Conferences, 2016 The largest uncertainties in the Standard Model calculation of the anomalous magnetic moment of the muon (g − 2)μ come from hadronic contributions. In particular, in a few years the subleading hadronic light-by-light (HLbL) contribution might dominate ...

Hot plasma effects on the dispersion properties of plasmaspheric hiss and its electron diffusion
地球与行星物理论评, 2023 Electron diffusion caused by plasmaspheric hiss is an important mechanism for the loss of electrons in Earth's inner magnetosphere; it has also been considered responsible for the formation of the slot region between inner and outer radiation belts.

Lorentz symmetry from a random Hamiltonian
, 2015 We match the density of energy eigenstates of a local field theory with that of a random Hamiltonian order by order in a Taylor expansion. In our previous work we assumed Lorentz symmetry of the field theory, which entered through the dispersion relation.

The dispersion relation of a dark soliton
New Journal of Physics, 2023 The energy-velocity relation of a dark soliton is usually derived by its exact solution, which has been used to explain the kinetic motion of the dark soliton widely in many-body physical systems.

Remote Sensing, 2023 Synthetic aperture radar (SAR) imagers are active microwave sensors that could overcome many challenges of passive optical bathymetry inversion, yet their capacity to yield accurate high-resolution bathymetric mapping is not studied sufficiently. In this

Excitation of nonlinear ion acoustic waves in CH plasmas
, 2016 Excitation of nonlinear ion acoustic wave (IAW) by an external electric field is demonstrated by Vlasov simulation. The frequency calculated by the dispersion relation with no damping is verified much closer to the resonance frequency of the small ...
