Direct Evidence of Drift‐Compressional Wave Generation in the Earth's Magnetosphere Detected by Arase

Geophysical Research Letters
We present the first direct evidence of an in situ excitation of drift‐compressional waves driven by drift resonance with ring current protons in the magnetosphere.

Mesoscopic Kondo Effect in an Aharonov-Bohm Ring

, 2000
An interacting quantum dot inserted in a mesoscopic ring is investigated. A variational ansatz is employed to describe the ground state of the system in the presence of the Aharonov-Bohm flux.

Ring Current Morphology From MMS Observations

Journal of Geophysical Research: Space Physics, 2022
AbstractWe directly estimate the in situ current density of the Earth’s ring current (RC) using the curlometer method and investigate its morphology using the small spatial separations and high accuracy of the Magnetospheric Multiscale mission. Through statistical analysis of data from September 2015 to the end of 2016, covering the region of 2–8 RE ...

Storm time dynamics of ring current protons: Implications for the long‐term energy budget in the inner magnetosphere

Geophysical Research Letters, 2016
Our investigation of the long‐term ring current proton pressure evolution in Earth's inner magnetosphere based on Van Allen Probes data shows drastically different behavior of the low‐ and high‐ energy components of the ring current proton population ...

Anomalous magnetic response of a quasi-periodic mesoscopic ring in presence of Rashba and Dresselhaus spin-orbit interactions

, 2016
We investigate the properties of persistent charge current driven by magnetic flux in a quasi-periodic mesoscopic Fibonacci ring with Rashba and Dresselhaus spin-orbit interactions.

Disentangling global and local ring currents

Chemical Science, 2022
Aromatic or antiaromatic ring currents – why not both? We use experimental NMR chemical shifts to identify both local and global ring currents in π-conjugated molecules.

Precipitation of Radiation Belt Electrons by EMIC Waves With Conjugated Observations of NOAA and Van Allen Satellites

Geophysical Research Letters, 2018
In this letter, we present unique conjugated satellite observations of MeV relativistic electron precipitation caused by electromagnetic ion cyclotron (EMIC) waves. On the outer boundary of the plasmasphere, the Van Allen probe observed EMIC waves.

The effects of particle injections on the ring current development during the 7-8 September 2017 geomagnetic storm

Frontiers in Astronomy and Space Sciences, 2023
In this study we investigate the role of particle injections on the ring current development during the 7-8 September 2017 geomagnetic storm by applying a temporally and spatially varying data-driven outer boundary condition in numerical simulations of ...
