Aharonov–Bohm effect for bound states in relativistic scalar particle systems in a spacetime with a spacelike dislocation

RLL Vitória, K Bakke - International Journal of Modern Physics D, 2018 - World Scientific
We investigate the analog effect of the Aharonov–Bohm effect for bound states in two
relativistic quantum systems in a spacetime with a spacelike dislocation. We assume that the …

Topological effects of a spiral dislocation on quantum revivals

AVDM Maia, K Bakke - Universe, 2022 - mdpi.com
We analyse the influence of spiral dislocation topology on the revival time for the harmonic
oscillator, for a particle confined to one-dimensional quantum ring, and a two-dimensional …

Harmonic oscillator in an elastic medium with a spiral dislocation

A Maia, K Bakke - Physica B: Condensed Matter, 2018 - Elsevier
We investigate the behaviour of a two-dimensional harmonic oscillator in an elastic medium
that possesses a spiral dislocation (an edge dislocation). We show that the Schrödinger …

Two-dimensional quantum ring in a graphene layer in the presence of a Aharonov–Bohm flux

JA Neto, MJ Bueno, C Furtado - Annals of Physics, 2016 - Elsevier
In this paper we study the relativistic quantum dynamics of a massless fermion confined in a
quantum ring. We use a model of confining potential and introduce the interaction via Dirac …

Noninertial effects on the ground state energy of a massive scalar field in the cosmic string spacetime

HF Mota, K Bakke - Physical Review D, 2014 - APS
We investigate the influence of noninertial effects on the ground state energy of a massive
scalar field in the cosmic string spacetime. We generalize the results obtained by …

Interaction of the magnetic quadrupole moment of a non-relativistic particle with an electric field in a rotating frame
