New Journal of Physics, 2021 Reaching gigagauss magnetic fields opens new horizons both in atomic and plasma physics. At these magnetic field strengths, the electron cyclotron energy ℏω _c becomes comparable to the atomic binding energy (the Rydberg), and the cyclotron frequency ω ...

The Solar Dynamo and Planetary Dynamo [PDF]
Symposium - International Astronomical Union, 1993 A dynamo driven by flows of differential rotation and global convection in a rotating sphere is reviewed as a model of the solar and planetary dynamos. The flows can amplify a magnetic field from an infinitesimal level and thus can generate a magnetic field.

Dynamic Modeling of Indole Glucosinolate Hydrolysis and Its Impact on Auxin Signaling
Frontiers in Plant Science, 2018 Plants release chemicals to deter attackers. Arabidopsis thaliana relies on multiple defense compounds, including indol-3-ylmethyl glucosinolate (I3G), which upon hydrolysis initiated by myrosinase enzymes releases a multitude of bioactive compounds ...

International Astronomical Union Colloquium, 1991 AbstractThe traditionalαΩ-dynamo as a model for the solar cycle has been successful in explaining the butterfly diagram, phase relations between poloidal and toroidal field, and polar branch migration features. Observational and theoretical achievements in recent years have however shaken this picture.

Laboratory evidence of dynamo amplification of magnetic fields in a turbulent plasma [PDF]
Nature Communications, 2017 Magnetic fields are ubiquitous in the Universe. The energy density of these fields is typically comparable to the energy density of the fluid motions of the plasma in which they are embedded, making magnetic fields essential players in the dynamics of ...

Fast and furious dynamo action in the anisotropic dynamo
Journal of Fluid Mechanics, 2022 In the limit of large magnetic Reynolds numbers, it is shown that a smooth differential rotation can lead to fast dynamo action, provided that the electrical conductivity or magnetic permeability is anisotropic. If the shear is infinite, for example between two rotating solid bodies, the anisotropic dynamo becomes furious, meaning that the magnetic ...
