CURRENT MAGNIFICATION AND CIRCULATING CURRENTS IN MESOSCOPIC RINGS

, 1995
We show that several novel effects related to persistent currents can arise in open systems, which have no analogue in closed or isolated systems. We have considered a system of a metallic ring coupled to two electron reservoirs.

Comprehensive evaluation of the vector magnetic field data from Macau Science Satellite-1A

Earth and Planetary Physics
In this study, we present a comprehensive evaluation of the magnetic field measurements from the Vector Field Magnetometer (VFM) aboard the recently launched Macau Science Satellite-1 (MSS-1). One-year data from November 2, 2023, to November 1, 2024, are

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.

Hidden quantum pump effects in quantum coherent rings

, 2003
Time periodic perturbations of an electron system on a ring are examined. For small frequencies periodic small amplitude perturbations give rise to side band currents which in leading order are inversely proportional to the frequency.

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 ...

Ring current proton decay by charge exchange [PDF]

Explorer 45 measurements during the recovery phase of a moderate magnetic storm have confirmed that the charge exchange decay mechanism can account for the decay of the storm-time proton ring current.

Multipoint MMS observations of fine‐scale SAPS structure in the inner magnetosphere

Geophysical Research Letters, 2016
We present detailed observations of dynamic, fine‐scale inner magnetosphere‐ionosphere coupling at ∼3.9 RE in the Region 2 Birkeland field‐aligned current (FAC). We find that observed electrodynamic spatial/temporal scales are primarily characteristic of
