Persistent currents in mesoscopic rings and conformal invariance

, 1998
The effect of point defects on persistent currents in mesoscopic systems is studied in a simple tight-binding model. Using an analogy with the treatment of the critical quantum Ising chain with defects, conformal invariance techniques are employed to ...

Geometry and linearly polarized cavity photon effects on the charge and spin currents of spin-orbit interacting electrons in a quantum ring

, 2013
We calculate the persistent spin current inside a quantum ring as a function of the strength of the Rashba or Dresselhaus spin-orbit interaction. We provide analytical results for the spin current of a one-dimensional (1D) ring of non-interacting ...

Nature of eigenstates in a mesoscopic ring coupled to a side branch

, 1996
We formalize the parity effect of a multichannel ring coupled to a side branch using the tight binding model. We find that the tight binding model gives slightly different result from the continuum model.

Self‐Regulating Feedback Between Field Line Curvature Scattering, Ring Current Pressure, and Magnetic Configuration

Geophysical Research Letters
We incorporate field line curvature (FLC) scattering into a kinetic ring current model two‐way coupled with a global magnetospheric MHD model to investigate its role in SYM‐H prediction and global magnetospheric dynamics.

Near‐Earth Reconnection Contributing to Recovery Phase of Geomagnetic Storm

Geophysical Research Letters
Recent observations show very near‐Earth reconnection (∼8–13RE) could efficiently power the ring current during the main phase of geomagnetic storms, but whether the recovery phase might be contributed remains unclear.
