“…These stripes have a negative slope on the spectrogram and repeat at about 1-second intervals, following the frequency of the KAWs. Similar distributions have been reported in recent observations of cyclotron wave-ion interactions and explained as nonlinear gyrophase bunching of ions by wave perpendicular electric fields 37 – 39 .…”

Kinetic Alfvén waves (KAWs) are ubiquitous throughout the plasma universe. Although they are broadly believed to provide a potential approach for energy exchange between electromagnetic fields and plasma particles, neither the detail nor the efficiency of the interactions has been well-determined yet. The primary difficulty has been the paucity of knowledge of KAWs’ spatial structure in observation. Here, we apply a particle-sounding technique to Magnetospheric Multiscale mission data to quantitatively determine the perpendicular wavelength of KAWs from ion gyrophase-distribution observations. Our results show that KAWs’ perpendicular wavelength is statistically 2.4$$\pm 0.7$$ ± 0.7 times proton thermal gyro-radius. This observation yields an upper bound of the energy the majority proton population can reach in coherent interactions with KAWs, that is, roughly 5.76 times proton perpendicular thermal energy. Therefore, the method and results shown here provide a basis for unraveling the effects of KAWs in dissipating energy and accelerating particles in a number of astrophysical systems, e.g., planetary magnetosphere, astrophysical shocks, stellar corona and wind, and the interstellar medium.

“…Within the confines of this structured boundary condition, sentient observers retain a significant degree of freedom. They possess the capability to dynamically, simultaneously, independently, and precisely manipulate the constitutive properties of resonant EM waves (Li et al, 2022). This manipulation, in turn, facilitates spatial and time-varying wave properties, leading to the generation of intricate waveforms and enabling direct information manipulation.…”

Constructive resonance, a fundamental phenomenon observed across various scales, plays a pivotal role in both quantum and astrophysical realms. This study delves into the dynamic intricacies of constructive resonance, exploring its implications for matter creation and the origin of force-fields like gravity. It posits that constructive wave couplings between fundamental particles induce a resonant attractive force akin to gravity at the subatomic level, conserving energy within the system. We conceptualize space-time as an interconnected fabric encoding linear and non-linear patterns within an Information Field, revealing interactions between fundamental particles as 'Constructive Resonance Waves,' giving rise to the material universe. Cosmic Information (CI) is introduced as a fundamental basis vector, tied to the dimensions of space and time, culminating in a 5-D universe. This paper introduces a novel theoretical framework encompassing Constructive Resonance and the Resonance-Induced Information Force Field (RIIFF)© parametrically represented by Rf to offer a dynamic perspective on fundamental forces. By integrating these concepts into existing theories, we unveil a fresh understanding of gravity, electromagnetism, and other forces. The RIIFF© framework, expressed as ∂F/∂t= ∇.Rf, elucidates how forces vary over time and space due to resonant interactions, providing a foundation for future research into the dynamic nature of the cosmos.

“…The launch of NASA's Magnetospheric Multiscale (MMS) mission (Burch et al., 2016) in 2015 has brought about significant advancements in this field by providing direct observations of the temporal evolution of particle distribution functions during these interactions. To date, various kinds of wave‐particle interactions have been studied using data collected from the MMS mission, including cyclotron resonance between electromagnetic ion cyclotron waves and ions (Kitamura et al., 2018; Li et al., 2022; Liu, Zong, Rankin, et al., 2022; Liu, Zong, Zhang, et al., 2022), cyclotron resonance between whistler waves and electrons (Kitamura et al., 2022), Landau resonance between kinetic Alfven waves and electrons (Gershman et al., 2017), Landau resonance between whistler waves and electrons (Liu et al., 2021), drift‐bounce resonance between ultra‐low‐frequency waves and ions (Li et al., 2021), electron Landau damping in turbulence (Afshari et al., 2021; Chen et al., 2019), as well as non‐resonant interactions (Liu et al., 2019, 2023; Shi et al., 2020).…”

Theoretical analysis has revealed a specific resonance that shares the same condition as Landau resonance, but instead involves wave electromagnetic fields rather than traditionally electrostatic fields. While this resonance, referred to as electromagnetic Landau resonance due to its properties, is considered significant for magnetospheric dynamics, rare reports or evaluations based on observations have been made thus far. Here, we present an event detected by the Magnetospheric Multiscale mission near the dayside magnetopause. During this event, ∼748‐eV protons are observed to be in resonance with a wave. Detailed data analysis demonstrates the resonant velocity closely matches the wave's parallel phase speed, which, combined with the significant work done by wave perpendicular electric field, confirms this interaction as electromagnetic Landau resonance. Further investigation indicates these protons are being secularly accelerated within this resonance. Consequently, our observations provide the first empirical evidence supporting the previously suggested theoretical importance of the electromagnetic Landau resonance.
