String Theory Seminar - Georgios Papathanasiou (DESY) Seminar

Speaker information

Georgios Papathanasiou , DESY Theory Group. Georgios is a theoretical physicist whose research focuses on Quantum Field Theory, String Theory, the relation between the two, and their fruitful interplay with contemporary mathematics. Performing explicit computations of important physical quantities at weak and strong coupling, and exploring their results to establish and exploit connections with new mathematical structures, lies at the core of my approach. In particular, he has achieved significant contributions in the study of quantities such as anomalous dimensions, string state energies, Wilson loops, and more recently scattering amplitudes, which form a bridge between theory and experiment. To this end, he employed and continued to further develop a wealth of complementary methods, ranging from gauge/string duality and integrability, to lattice discretization, and the exploitation of the expected analytic behavior of the relevant physical quantity. Ultimately, his research aims towards an all-loop solution of an interacting, four-dimensional gauge theory, for the simplest example of planar, maximally supersymmetric Yang-Mills theory. It is very likely that along the way, the new insights gained and computational tools built, will also find applications to the real world of elementary particles, and their interactions.
