Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2017ja023969

Abstract: Electron dynamics surrounding the X-line in magnetopause-type asymmetric reconnection is investigated using a two-dimensional particle-in-cell simulation. We study electron properties of three characteristic regions in the vicinity of the X-line. The fluid properties, velocity distribution… read more here.

Published in 2017 at "Journal of Computational Chemistry"

DOI: 10.1002/jcc.24896

Abstract: In this contribution, we extend our framework for analyzing and visualizing correlated many‐electron dynamics to non‐variational, highly scalable electronic structure method. Specifically, an explicitly time‐dependent electronic wave packet is written as a linear combination of… read more here.
