A new paradigm for fast and repetitive chirping of Alfvén eigenmodes

open access: yesNuclear Fusion, 2023
A novel 2D nonlinear dynamical paradigm is constructed to interpret the fast and repetitive frequency chirping and amplitude oscillation of Alfvén eigenmodes excited by energetic particles in fusion plasmas as observed in global gyrokinetic simulations ...

Determination of the interaction impedance of helix slow-wave structures. [PDF]

open access: yes, 2000
The computer simulation of helix travelling-wave tubes requires accurate information about the phase velocity, interaction impedance and attenuation of the helix slow wave structure at each frequency.

Wave Propagation in Granular Materials [PDF]

open access: yes, 2005
Wave propagation is a fundamental property of all physical systems. The wave speed is directly related to the compressibility of the system and determines the rate at which local disturbances are propagated into the bulk of the material.

Wave-particle interactions toolset: A python-based toolset to model wave-particle interactions in the magnetosphere

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Wave particle interactions are known to be an efficient yet unquantified driver of the variability of particle populations in Earth’s magnetosphere, and their quantification and understanding through modelling has been a subject of ceaseless and ...

Wave-Particle Interaction in the Ionosphere and magnetosphere

open access: yesAntarctic Record, 1979
Wave-particle interactions that are important processes for the control of the electromagnetic states in the earth's magnetosphere are surveyed relatingto the auroral zone that is the most suitable window to clarify the various aspects of wave-particle ...

Direct Evidence of the Pitch Angle Scattering of Relativistic Electrons Induced by EMIC Waves

open access: yesGeophysical Research Letters, 2020
In this study, we analyze an electromagnetic ion cyclotron (EMIC) wave event of rising tone elements recorded by the Van Allen Probes. The pitch angle distributions of relativistic electrons exhibit a direct response to the two elements of EMIC waves: at

Hydrodynamic quantum field theory: the free particle

open access: yesComptes Rendus. Mécanique, 2020
We revisit de Broglie’s double-solution pilot-wave theory in light of insights gained from the hydrodynamic pilot-wave system discovered by Couder and Fort []. de Broglie proposed that quantum particles are characterized by an internal oscillation at the

Computational and theoretical study of the wave-particle interaction of protons and waves [PDF]

open access: yesAnnales Geophysicae, 2012
We study the wave-particle interaction and the evolution of electromagnetic waves propagating through a plasma composed of electrons and protons, using two approaches.

Comparative Study of Dayside Pulsating Auroras Induced by Ultralow-Frequency Waves

open access: yesUniverse, 2023
Pulsating auroras are usually observed with ultralow-frequency (ULF) waves in the Pc 3–5 band (period 10–600 s). These auroras are thought to result from interactions between energetic electrons and chorus waves, but their relationship with ULF waves ...

The competition of tensor interaction and neutron-proton pairing in the beta-decay of the neutron-rich isotopes [PDF]

open access: yesEPJ Web of Conferences, 2019
The effects of the residual interaction in the particle-particle channel on β-decay characteristics and the multi-neutron emission probabilities in the β-decay of 126,128,130,132Cd are studied within the quasiparticle random phase approximation with the ...
