Locating the magnetospheric ring current [PDF]

Protons are studied in the global depression of the earth's horizontal magnetic field. It is shown that 10 to 100 keV protons dominate ring current energetics in two preferred regions of cyclotron instability, which serve as stable trapping boundaries ...

Spontaneous Currents in a Bosonic Ring

Acta Physica Polonica A, 2016
Nonequilibrium dynamics of noninteracting bosons in a one-dimensional ring-shaped lattice is studied by means of the Kinetic Monte Carlo method. The system is approximated by the classical XY model (the kinetic term is neglected) and then the simulations are performed for the planar classical spins.

Suppression of level hybridization due to Coulomb interactions

, 1998
We investigate an ensemble of systems formed by a ring enclosing a magnetic flux. The ring is coupled to a side stub via a tunneling junction and via Coulomb interaction.

Filamentary Currents and Alfvénic Vortices in the Inner Magnetosphere

Geophysical Research Letters, 2020
We show that broadband low‐frequency Alfvénic field variations observed in the inner‐magnetosphere from the Van Allen Probes during geomagnetically disturbed intervals are composed of multiscale current sheets, current filaments, flow shears, and ...

Crossover from hc/e to hc/2e current oscillations in rings of s-wave superconductors

, 2008
We analyze the crossover from an hc/e-periodicity of the persistent current in flux threaded clean metallic rings towards an hc/2e-flux periodicity of the supercurrent upon entering the superconducting state. On the basis of a model calculation for a one-

Superconducting fluctuation current in a space with the Kerr metric

, 2019
We study a fluctuation current through a superconducting ring placed in a space with the Kerr metric. This attempt aims at exploring conceptual problem; namely, we are concerned with the question about the condensed state in an extreme space-time.

Reduced Order Probabilistic Emulator of RAM‐SCB: Toward Non‐Linearity With Autoencoders

Space Weather
An accurate understanding of the Earth's ring current dynamics is integral to predicting the impacts of geomagnetic storms. We use physics‐based models to simulate the ring current such as the Ring‐current Atmosphere interactions Model with Self ...

Fano effect in a ring-dot system with tunable coupling

, 2006
Transport measurements are presented on a quantum ring that is tunnel-coupled to a quantum dot. When the dot is in the Coulomb blockade regime, but strongly coupled to the open ring, Fano line shapes are observed in the current through the ring, when the
