This occurs through the introduction of a natural length scale and is associated with phenomena such as the Hagedorn transition.

We analyze the black hole geometry and derive the effective potential governing the motion of the test particle, showing the influence of the BH charge <em>Q</em> and the parameter <em>α</em> on the motion of the particle. Using the Hamiltonian formalism, we determine the angular momentum, energy, and innermost stable circular orbits of the particles, demonstrating that increasing <em>Q</em> and <em>α</em> shifts the innermost stable circular orbit radii closer to the horizon and reduces the stability of the orbit. The effective force acting on the particles becomes more attractive with higher <em>Q</em> and <em>α</em>. Harmonic oscillatory motion around stable orbits reveals distinct radial, latitudinal, and axial frequencies, which diminish near the horizon for larger <em>Q</em> and <em>α</em>.

The center of mass energy near the horizon escalates with <em>Q</em> and <em>α</em>, suggesting enhanced energy extraction efficiency.
