Nonlinear dispersion relation in integrable turbulence [PDF]
Scientific Reports, 2022 We investigate numerically and experimentally the concept of nonlinear dispersion relation (NDR) in the context of partially coherent waves propagating in a one-dimensional water tank.

Analytical Dispersion Equations of a Lossy Coaxial Waveguide in the Microwave and Visible Spectra [PDF]
Journal of Electromagnetic Engineering and Science, 2021 Analytical hybrid-mode dispersion relations of a lossy coaxial waveguide were rigorously analyzed using a mode-matching technique. In order to model a practical coaxial line with inevitable losses, we adopted an all-dielectric coaxial waveguide ...

Quasi-linear analysis of dispersion relation preservation for nonlinear schemes
Advances in Aerodynamics, 2022 In numerical simulations of complex flows with discontinuities, it is necessary to use nonlinear schemes. The spectrum of the scheme used has a significant impact on the resolution and stability of the computation.

String with deformed dispersion relation
European Physical Journal C: Particles and Fields, 2022 We study string theory with momentum living on de Sitter space. We argue that consistency of the theory implies that the global momentum can be defined on de Sitter space.

Dispersion relation of electromagnetic ion cyclotron waves using Cluster observations [PDF]
Annales Geophysicae, 2013 Multi-point wave observations on Cluster spacecraft are used to infer the dispersion relation of electromagnetic ion cyclotron (EMIC) waves. In this study we use a phase differencing method and observations from STAFF and WHISPER during a well-studied

A dispersion relation for defect CFT
Journal of High Energy Physics, 2023 We present a dispersion relation for defect CFT that reconstructs two-point functions in the presence of a defect as an integral of a single discontinuity.

Dispersion relations, capillary waves, and the Rayleigh-Plateau instability [PDF]
INCAS Bulletin, 2022 The paper shows the importance of the dispersion relation in characterizing the capillary waves seen on liquid jets. Several theoretical models are given to better understand the stability of cylindrical interfaces when various parameters are considered,

Crossing antisymmetric Polyakov blocks + dispersion relation
Journal of High Energy Physics, 2022 Many CFT problems, e.g. ones with global symmetries, have correlation functions with a crossing antisymmetric sector. We show that such a crossing antisymmetric function can be expanded in terms of manifestly crossing antisymmetric objects, which we call

Frontiers in Materials, 2022 We study the propagation of bending waves along the free edge of a semi-infinite piezoelectric plate within the framework of two-variable refined plate theory (TVPT, a high-order plate theory), Reissner-Mindlin refined plate theory (RMPT, a first-order ...

Dispersion relation for CFT four-point functions
Journal of High Energy Physics, 2020 We present a dispersion relation in conformal field theory which expresses the four point function as an integral over its single discontinuity. Exploiting the analytic properties of the OPE and crossing symmetry of the correlator, we show that in ...
