| Abstract: |
AdS/CFT provides two very different descriptions on of the same spectrum at weak and strong 't Hooft coupling respectively. In the former case the basic degrees of freedom are the gluons (and superpartners) of the gauge theory while in the latter case we have a dual weakly coupled description in terms of semiclassical closed strings. As with other weak/strong coupling dualities it is natural to ask how the weakly coupled degrees of freedom of one description are manifested in the other (A classic example is the sine-Gordon kink which corresponds to the elementary fermion of the dual Thirring model). I will present some results which illuminate this question. |
