Confinement effects of Aharonov–Bohm (AB) flux and magnetic fields with topological defect on \(CO\) diatomic molecule modeled by screened modified Kratzer potential is investigated in this paper. The all-encompassing effects of the fields and topological defect result in a strongly repulsive system. We discover that the collective effect of the fields and defect is more intense than the lone and dual effect and consequently there is a substantial shift in the bound state energy of the system. We also find that to sustain a low-energy medium for the molecule modeled by SMKP, the topological defect and weak AB field are required, whereas the magnetic field can be used as a control parameter or enhancer. The effects of the topological defect and magnetic and AB fields on the thermal and magnetic properties of the system are duly analyzed. We observe that the system tends to exhibit both a paramagnetic and diamagnetic behavior for weak and intense magnetic field, respectively, and some sort of saturation at high magnetic field. To further validate our findings, we map our result to 3D and a comparison of our results with what one obtains in literature reveals an excellent agreement.

拓扑缺陷对$$ CO $$ CO双原子分子能谱和热磁性能的影响

Aharonov–Bohm(AB)通量和具有拓扑缺陷的磁场对\(CO \)的约束效应本文研究了筛选的修饰的Krtzer势建模的双原子分子。场和拓扑缺陷的全面影响导致了强排斥系统。我们发现,场和缺陷的集体效应比孤独和双重效应更为强烈,因此系统的束缚态能量发生了实质性的转变。我们还发现,要维持由SMKP建模的分子的低能量介质,就需要拓扑缺陷和弱AB场,而磁场可以用作控制参数或增强剂。分析了拓扑缺陷,磁场和AB场对系统热和磁性能的影响。我们观察到,对于弱磁场和强磁场,该系统倾向于同时表现出顺磁和反磁行为,而在高磁场下,该系统倾向于表现出某种饱和度。为了进一步验证我们的发现,我们将结果映射到3D并将我们的结果与文献中获得的结果进行了比较,这表明了极好的一致性。
