DOI: 10.1002/2017gl072676
Abstract: The nonlinear response of the cross polar cap potential (CPCP) to solar wind driving electric field is a well-known phenomenon. The reasons behind this saturation, however, are still under debate. We have performed a statistical… read more here.

DOI: 10.1007/s11214-019-0616-8
Abstract: Polar cap airglow patches have been known as regions of enhanced 630.0 nm airglow detected by ground-based all-sky imagers at the polar cap latitudes well inside the main auroral oval. Although they were already recognized almost… read more here.

DOI: 10.1016/j.jastp.2017.11.015
Abstract: Abstract In some simple models of magnetospheric electrodynamics [e.g., Volland, Ann. Geophys., 31, 154–173, 1975], the normal component of the convection electric field is discontinuous across the boundary between closed and open magnetic field lines,… read more here.

DOI: 10.1093/mnras/stx731
Abstract: It is shown that the time-variability inherent in the ion-proton polar cap leads naturally to growth of Langmuir modes on narrow bundles of magnetic flux lines and that the observed size of micropulses is consistent… read more here.

DOI: 10.1093/mnrasl/sly183
Abstract: Current closure in the pulsar magnetosphere holds the key to its structure. We must determine not only the global electric circuit, but also the source of its electric charge carriers. We address this issue with… read more here.
