Residuals to the CHAOS‐6 Geomagnetic Field Model Caused by Magnetospheric Currents During Enhanced Magnetic Activity

Geochemistry, Geophysics, Geosystems, 2020
Thanks to mapping missions, like Ørsted, CHAMP, and Swarm, we have gained a detailed understanding of the geomagnetic field. High‐resolution models like POMME, GRIMM, or CHAOS are able to describe the main parts of the Earth's magnetic field reliably ...

Anomalous phase shift in a twisted quantum loop

, 2010
Coherent motion of electrons in a twisted quantum ring is considered to explore the effect of torsion inherent to the ring. Internal torsion of the ring composed of helical atomic configuration yields a non-trivial quantum phase shift in the electrons ...

Geomagnetic response to solar and interplanetary disturbances

Journal of Space Weather and Space Climate, 2013
The space weather discipline involves different physical scenarios, which are characterised by very different physical conditions, ranging from the Sun to the terrestrial magnetosphere and ionosphere.

Persistent current magnification in a double quantum-ring system

, 2005
The electronic transport in a system of two quantum rings side-coupled to a quantum wire is studied via a single-band tunneling tight-binding Hamiltonian. We derived analytical expressions for the conductance, density of states and the persistent current

Near‐Earth Reconnection Contributing to Recovery Phase of Geomagnetic Storm

Geophysical Research Letters
Recent observations show very near‐Earth reconnection (∼8–13RE) could efficiently power the ring current during the main phase of geomagnetic storms, but whether the recovery phase might be contributed remains unclear.

The role of the dynamic terrestrial exosphere in the storm-time ring current decay

Frontiers in Astronomy and Space Sciences
The charge exchange interaction between exospheric hydrogen (H) atoms and energetic ions in the terrestrial ring current is a crucial mechanism for dissipating global magnetospheric energy, especially during the recovery phase of geomagnetic storms ...

Decoherence from Vacuum Fluctuations

, 2001
Vacuum fluctuations are a source of irreversibility and decoherence. We investigate the persistent current and its fluctuations in a ring with an in-line quantum dot with an Aharonov-Bohm flux through the hole of the ring.
