Some judiciously chosen 4D Yang-Mills theories with various degree of supersymmetry (including no SUSY) support “Non-Abelian string solitons”, i.e. vortex strings with extra moduli on the string world sheet. The emerging target space theories on the world sheet are non-trivial, implying a number of consequence and novel applications both in HEP and condensed matter. I discuss some of them. For … Read More
We study the evolution of the Gregory-Laflamme instability for black strings in global AdS spacetime, and investigate the CFT dual of the formation of a bulk naked singularity. Using an effective theory in the large D limit, we uncover a rich variety of dynamical behaviour, depending on the thickness of the string and on initial perturbations. These include: large inflows … Read More
Abstract: I will present a model of self-interacting dark matter (SIDM) based on the low energy effective theory of supersymmetric QCD. Velocity dependent self interactions are achieved by a s-channel resonance in the non-relativistic limit generated by a mass ratio fixed by the flavor symmetry. The model is also fairly predictive; the dark matter mass would be required to be around … Read More
