CURRENT MAGNIFICATION AND CIRCULATING CURRENTS IN MESOSCOPIC RINGS [PDF]
Physica 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.

Spontaneous currents in a bosonic ring [PDF]
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

Disentangling global and local ring currents. [PDF]
Chem 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.

Probing the BCS-BEC crossover with persistent currents
Physical Review Research, 2021 We study the persistent currents of an attractive Fermi gas confined in a tightly confining ring trap and subjected to an artificial gauge field all through the BCS-BEC crossover. At weak attractions, on the Bardeen-Cooper-Schrieffer (BCS) side, fermions

Frontiers in Astronomy and Space Sciences, 2022 Large-scale current systems in the ionosphere and the magnetosphere are intimately controlled by the solar wind-magnetosphere interaction and the magnetosphere-ionosphere coupling.

Macedonian Journal of Chemistry and Chemical Engineering, 2012 Within a systematic study of cyclic conjugation in the benzo-annelated derivatives of acenaphthylene and fluoranthene, a general regularity was discovered, named phenyl-cyclopentadienyl rule (PCP rule).

The Magnetic Response of Starphenes
Chemistry, 2021 The aromaticity of [n]starphenes (n = 1, 4, 7, 10, 13, 16), as well as starphene-based [19]dendriphene, is addressed by calculating the magnetically induced current density and the induced magnetic field, using the pseudo-π model.

Long-term evolution of magnetospheric current systems during storms [PDF]
Annales Geophysicae, 2004 We present a method to model the storm-time magnetospheric magnetic field using representations of the magnetic field arising from the various magnetospheric current systems.

Laser-controlled local magnetic field with semiconductor quantum rings [PDF]
, 2005 We analize theoretically the dynamics of N electrons localized in a semiconductor quantum ring under a train of phase-locked infrared laser pulses. The pulse sequence is designed to control the total angular momentum of the electrons.
