In this work, the quantisation of particle propagating in a dissipative harmonic medium will be investigated using the creation and annihilation operator formalism, which is more appropriate in some fields of physics. Modelling the problem as damped

The (extended) Nikiforov–Uvarov method is employed to find exact solutions of the Schrodinger operator for three $$\mathcal {PT}$$-invariant potentials (periodic exponential, cotangent and $$\mathcal {PT}$$-symmetric harmonic plus centrifugal). It

In this paper, we used the scaling concepts of Mandelbrot of fractals in variational problems of mechanical systems in order to re-write the action integral function as an integration over the fractional time. In addition, by applying the variational
