| Classification of Minimal Unitary 3d N=4 Coulomb Branches |
| Speaker: | Sinan MOURA SOYSÃREN (University of Vienna) |
| Abstract: | Obtaining the classification of 3d N=4 quiver theories whose Coulomb Branches have an isolated symplectic singularity is an essential step in understanding moduli spaces of vacua of supersymmetric theories with 8 supercharges in any dimensions. Using the Decay and Fission algorithm, the complete list of such unitary quiver theories can be derived, reproducing known results and giving rise to previously unknown families. |

| A panoramic view of low dimensional manifolds |
| Speaker: | Willi Kepplinger (University of Vienna) |
| Abstract: | The character and status of very simple sounding questions in manifold theory depends crucially on the dimension of the manifold. An illustrative example is the famous Jordan curve theorem which roughly speaking states that a topological embedding of S^1 into R^2 separates R^2 into a bounded component (which is homeomorphic to a disk) and an unbounded one. Naively speaking this theorem seems obvious, if annoying to prove. In reality, it is a miracle it is true in the first place as corresponding statements in dimension 3 and higher are simply wrong. In this talk I will try to give an overview over questions in low dimensional topology (such as existence and uniques of smooth structures, classification of manifolds) and how these depend on the dimension. |

| Generalised Fluid Dynamics |
| Speaker: | Jacopo de Nardis (LPTM - Cergy Paris Université) |
| Abstract: | I will present the theory of generalised hydrodynamics, and its discretisation in terms of gases of interacting wave packets, which applies to integrable systems in 1+1D (both quantum and classical) and quasi-integrable under external perturbations (external trapping potentials or non-integrable inter-particle potentials).

| Speaker: | Gerhard Rempe (MPQ) |
| Abstract: | Entanglement is a genuine quantum physics concept that has so far mostly been studied with only a few qubits. However, generating customised multi-qubit entanglement is a formidable challenge, especially in distributed quantum networks. The talk will present a unique approach to generate a zoo of almost arbitrary entanglement topologies described by graphs. These open the door to a multi-node quantum internet, a measurement-based quantum computer and a one-way quantum repeater. |
