Topological effects of a global monopole on a spherical quantum dot

Abstract

We consider a spherical quantum dot described by an attractive short-range potential and search for topological effects of a global monopole on it. The attractive short-range potential is built from the power-exponential potential model in Ciurla et al. (2022 Physica E 15 , 261–268 ( doi:10.1016/S1386-9477(02)00572-6 )), where we focus on a particular case proposed by this quantum dot model. In search of bound states, we deal with s -waves. We thus obtain the energy eigenvalues and discuss the effects of the topology of the global monopole on them. Further, we extend our discussion to the quantum revivals.

Lorentz Symmetry Violation Effects Caused by the Coupling between the Field fμγ5 and the Derivative of the Fermionic Field on One-Dimensional Potentials

“…We should observe that the scalar exponential potential (45) has been used to describe spherical quantum dots [51,52]. Therefore, we have another example of nanostructures that provide us with insights into the search for Lorentz symmetry breaking effects in low energies [6].…”
