The Magnetic Response of Starphenes

open access: yesChemistry, 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.

Impact of the current density on paramagnetic NMR properties

open access: yes, 2022
Meta-generalized gradient approximations (meta-GGAs) and local hybrid functionals generally depend on the kinetic energy density τ. For magnetic properties, this necessitates generalizations to ensure gauge invariance.

Stability of Current Density Impedance Imaging [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2020
We study stability of reconstruction in current density impedance imaging (CDII), that is, the inverse problem of recovering the conductivity of a body from the measurement of the magnitude of the current density vector field in the interior of the object.

The Oriented and Flux-Weighted Current Density Stagnation Graph of LiH

open access: yes, 2022
A scheme is introduced to quantitatively analyze the magnetically induced molecular current density vector field J. After determining the set of zero points of J, which is called its stagnation graph (SG), the line integrals -1/mu_0 \int_li B.dl along ...
