Linearized ring current models for the retrieval of π ring current strength in monocycles

Chemical Physics Letters, 2013
Abstract Three different ring current models (RCMs) have been used to study the relationship between the π contribution to parallel NICS scans and the ring current strength for monocycles. The models have been linearized and they have been applied to retrieve the ab initio ring current strengths in a set of 28 organic and inorganic monocycles ...

The terrestrial ring current

Journal of Geophysical Research, 1964
Several people have computed numerically the magnetic field caused by an axially symmetric body of plasma imbedded in a dipole magnetic field. In the present paper we derive an approximate formula for this magnetic field, without first choosing a particular functional form for the plasma density.

Dynamic persistent currents in mesoscopic rings

Physical Review Letters, 1991
A dynamic current I w in a mesoscopic ring subjected to a time-dependent external magnetic field H~(t)=H 0 +H w cos(ωt) is calculated in the limit of small Hω using linear-response theory and the supersymmetry method. It is shown that the current Iω remains finite in the limit ω→0 and exceeds currents obtained from thermodynamic considerations. It can
