Tunneling of a composite particle effect

This paper investigates the tunneling process of a composite particle, particularly focusing on the effects of intrinsic degrees of freedom, which have not been sufficiently explored in the literature. The objective is to demonstrate how the probabilities of tunneling can be enhanced by weak external fields or the polarizability of these composite objects. Employing simple theoretical models, we analyze the implications of intrinsic structure on the tunneling dynamics. The results indicate that the tunneling probability for loosely bound systems, such as the deuteron, can significantly exceed conventional estimates, highlighting the importance of considering the internal structure of composite particles in nuclear reactions. The findings have implications for a variety of physical contexts, including nuclear fusion, nucleosynthesis in stars, and molecular processes, as well as transport phenomena in both semiconductors and superconductors. This study elucidates the complex interplay between the intrinsic properties of particles and their tunneling behavior, suggesting avenues for future research in theoretical and experimental frameworks.
