CURRENT MAGNIFICATION AND CIRCULATING CURRENTS IN MESOSCOPIC RINGS [PDF]

open access: yesPhysica B: Condensed Matter, 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.

Disentangling global and local ring currents. [PDF]

open access: yesChem Sci, 2023
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.

Spontaneous currents in a bosonic ring [PDF]

open access: yesActa 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

Current Correlations in a Quantum Dot Ring: A Role of Quantum Interference

open access: yesEntropy, 2019
We present studies of the electron transport and circular currents induced by the bias voltage and the magnetic flux threading a ring of three quantum dots coupled with two electrodes.

Are Metallacyclopentadienes Always Non-Aromatic?

open access: yesChemistry, 2021
Even though metallacyclopentadienes (MCPs) are among the most common metallacycles, their electron delocalization (aromaticity) has received far less attention than other metallacycles, such as metallabenzenes.

Relationships between field-aligned currents and convection observed by EISCAT and implications concerning the mechanism that produces region-2 currents: Statistical study [PDF]

open access: yesAnnales Geophysicae, 1994
Fluid theories explain the origin of region-2 field-aligned currents as the closure of the ring current, driven itself by the azimuthal pressure gradients generated in the magnetospheric ring plasma by the sunward convection. Although the structure of

Statistical analysis of storm-time near-Earth current systems [PDF]

open access: yesAnnales Geophysicae, 2015
Currents from the Hot Electron and Ion Drift Integrator (HEIDI) inner magnetospheric model results for all of the 90 intense storms (disturbance storm-time (Dst) minimum < −100 nT) from solar cycle 23 (1996–2005) are calculated, presented, and ...

Morphology of the ring current derived from magnetic field observations [PDF]

open access: yesAnnales Geophysicae, 2004
Our examination of the 20 years of magnetospheric magnetic field data from ISEE, AMPTE/CCE and Polar missions has allowed us to quantify how the ring current flows and closes in the magnetosphere at a variety of disturbance levels.
