In this work, quantum effects are discussed which arise from the interaction between an electric quadrupole moment and electric fields. It is shown that, by choosing a diagonal electric quadrupole tensor whose components are constants, the interaction between an electric quadrupole moment and electric fields gives rise to the scalar Aharonov‐Bohm effect and to bound states analogous to the confinement of a quantum particle to a quantum dot. Moreover, the influence of a constant force field on the confinement analogous to a quantum dot, and the influence of an antidot‐like potential on the Landau levels of an electric quadrupole moment are discussed.
