Comment on “Magnetic field effects on oscillator strength, dipole polarizability and refractive index changes in spherical quantum dot”

Abstract Yakar et al. (2018) investigated the optical properties of spherical quantum dot such as the oscillator strength, the static dipole polarizability and the refractive index changes as a function magnetic field strength. We studied their article and we found that there are some mistakes in their optical calculations. The selection rules on the quantum number m that they used to obtain allowed intersubband transitions are not correct. Here, we introduce the correct selection rules.
