| Research Abstract |
We studied relation between D-branes in superstring theory and solitons in field theories, and we obtained an interesting insight on the applications in both directions among them. We used the fact that D-branes represent baryons in application of gauge/gravity correspondence in superstring theory. Using a solitonic representation of D-branes, we could obtain various properties of baryons in quantum chromo-dynamics. These include charge radii, magnetic moments of nucleons, nuclear forces and repulsive cores of nucleons, and nuclear giant resonances.
