Analyzing the Effects of Topological Defect (TD) on the Energy Spectra and Thermal Properties of LiH, TiC and I2 Diatomic Molecules

Abstract

In this study, the impacts of TD on the energy spectra and thermal properties of LiH, TiC and I2 diatomic molecules is considered. The Schrodinger equation in cosmic string spacetime is solved with the generalized Morse potential using the well-known (NU) method. The energy spectra and eigenfunction are obtained respectively. The energy spectra is used to obtain the partition function which is then used to evaluate the thermal properties of the system is evaluated accordingly. We find that the energy spectra in the presence of the TD differ from their flat Minkowski spacetime analogue. The effects of the deformation parameter and TD on the thermal properties of the system is also analysed in detail. We observe that the specific heat capacity of the system tends to exhibit quasi-saturation as the deformation parameter and topological defect approaches unity. The results of our study can be applied in the astrophysical situation where these modifications exist in the understanding of spectroscopical data and it may be used as a probe of the presence of a cosmic string or a global monopole in the Universe.

Confinement effects of external fields and topological defect on hydrogen atom in a quantum-plasma environment

“…Numerous papers [7][8][9][10][11][12][13][14][15][16][17][18]16] have investigated the effects of an external electric and magnetic field on the hydrogen atom. We propose that, in addition to using AB and magnetic fields to regulate the energy levels or localization of a hydrogen atom's quantum state in quantum plasmas, the topological defect could be used.…”

“…Both articles considered the hydrogen atom in Minkwoski space but in the present study, we have taken a step forward to consider the effect of a defect in the medium. In various areas of physics, such as gravitation [17], condensed matter physics [18], etc., the study of the effect of topology on the physical properties of various systems has been of critical relevance and this has been greatly studied by several authors [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. Hydrogen atom has been studied in a medium with topological defect by several authors [38][39].…”
