Three-dimensional wormhole with cosmic string effects on eigenvalue solution of non-relativistic quantum particles

Abstract

AbstractIn this paper, we explore the quantum system of non-relativistic particles in a unique scenario: a circularly symmetric and static three-dimensional wormhole space-time accompanied by cosmic strings. We focus on a specific case where the redshift function $$\varPhi (r)$$ Φ ( r ) to be zero and defining the shape function as $$A(r)=\frac{b}{r^2}$$ A ( r ) = b r 2 . After establishing this background space-time, we investigate the behavior of a harmonic oscillator within the same wormhole context. By doing so, we observe the effects of the cosmic string and wormhole throat radius on the eigenvalue solution of the oscillator’s eigenvalue problem. The primary finding is that these cosmic features lead to modifications in the energy spectrum and wave functions of the system, breaking the degeneracy of energy levels that would typically be present in a more conventional setting. As a particular case, we present the specific energy level $$E_{1,\ell }$$ E 1 , ℓ and the corresponding wave function $$\psi _{1,\ell }$$ ψ 1 , ℓ , which are associated with the ground state of the quantum system. These results highlight the fascinating and unique properties of the harmonic oscillator in the background of a circularly symmetric, static wormhole space-time with cosmic strings.
