  In this work, we investigate the combined influence of the nontrivial
topology introduced by a disclination and non inertial effects due to rotation,
in the energy levels and the wave functions of a noninteracting electron gas
confined to a two-dimensional pseudoharmonic quantum dot, under the influence
of an external uniform magnetic field. The exact solutions for energy
eigenvalues and wave functions are computed as functions of the applied
magnetic field strength, the disclination topological charge, magnetic quantum
number and the rotation speed of the sample. We investigate the modifications
on the light interband absorption coefficient and absorption threshold
frequency. We observe novel features in the system, including a range of
magnetic field without corresponding absorption phenomena, which is due to a
tripartite term of the Hamiltonian, involving magnetic field, the topological
charge of the defect and the rotation frequency.
