Sec. 4 we construct a simple model to study light nuclei such as $^{2}D$, $^{3}T$, $^{3}He$ and $^{4}He$ and obtain their potential of ground and excited states and respective binding energies. Section 6 is devoted to a brief summary and conclusions. Also, some other topics which are studied using the duality, are introduced in this section.

Quantum Chromodynamics (QCD) is the quantum field theory of the strong interactions which has two important properties, asymptotic freedom and confinement. Various analytical and numerical methods have been developed to study QCD. One example is perturbative QCD which works at small distances where the coupling is weak, but fails to work at larger distances where the coupling becomes relatively strong in which case the problem is said to become non-perturbative. Examples of methods that study non-perturbative problems are effective field theories such as chiral perturbation theory, lattice QCD \[54\], Dyson-Schwinger equations (DSE) formalism \[55\] and gauge/gravity duality \[12,56-57\].

Before QCD, in the 1960’s string theory was introduced as a model to describe the strong interactions \[58\]. It was able to explain the organization of hadrons in Regge trajectories, describing them as rotating strings. After the formulation
