Calendar of Physics Talks Vienna
| Strings, Branes, Schwarzian action and Maximal Chaos |
| Speaker: | Avik Banerjee (Saha Institut of Nuclear Physics, India) |
| Abstract: | Large N CFTs with Einstein gravity dual are known to saturate the chaos bound, i.e, λ=2π/(β). In my talk I shall discuss how maximal chaos occurs for a generic, probe quark-like defect degrees of freedom, for both scalar and vector operators, in a strongly coupled large N_C gauge theory. In holography, this corresponds to the dynamics of open string degrees of freedom, in the background of a closed string geometric background. The corresponding maximal chaos is governed by an intrinsic defect D-brane horizon. In this context, I shall show that a Schwarzian effective action emerges, in the infra-red, from an open string worldsheet, as well as a D1-brane worldvolume, embedded in AdS. I shall further elaborate on the connection between the emergence of Schwarzian effective action and the chaos bound saturation, which also happens to be the story for Jackiw- Teitelboim theory. |

| Imaging Fundamental Processes: The story and stories of jets at accelerators |
| Speaker: | George F. Sterman (SUNY, Stony Brook) |
| Abstract: | 2. Vorlesung im Rahmen der Schrödinger Gastprofessur 2018:
Jets at particle colliders are our window into fundamental reactions, which often proceed through confined degrees of freedom that are invisible at long distances. I’ll review some of the history and theory of particle jets, and how they reflect a crossroads between classical and quantum phenomena. |
