Bound states of a charged particle in the field of an electric quadrupole in two dimensions
(Springer, 2014-02)
The Schrödinger equation for a charged particle in the field of a nonrelativistic electric quadrupole in two dimensions is known to be separable in spherical coordinates. We investigate the occurrence of bound states of ...

Comment on: “Quantum aspects of a moving magnetic quadrupole moment interacting with an electric field” [J. Math. Phys. 56, 062107 (2015)]
(American Institute of Physics, 2021-01)
We analyze the results obtained for the quantum dynamics of a moving particle with a magnetic quadrupole moment interacting with electric and magnetic fields. We argue that there are no bound states contrary to what the ...
Ab initio study of the EFG at the N sites in imidazole
(SPRINGER, 2008)
We study the nuclear quadrupole interaction at the nitrogen sites in the molecular and crystalline phases of the imidazole compound. We use PAW which is a state-of-the-art method to calculate the electronic structure and ...
Motion of test particles in the field of a naked singularity
(American Physical Society, 2016)
We investigate the motion of test particles in the gravitational field of a static naked singularity generated by a mass distribution with a quadrupole moment. We use the quadrupole metric (q metric) which is the simplest ...
