Journal Club: Information Geometry in Epidemiology and Population Dynamics
Speaker: Stefan Hohenegger, Senior Researcher Abstract: In this talk I introduce basic concepts in information theory and apply them to epidemiology and population dynamics: I start by reformulating simple evolution models in terms of probability distributions. This allows me to construct the Fisher information, which I interpret as the metric of a one-dimensional differentiable manifold. For systems that can be effectively described by a single degree of freedom, I show that their time evolution is fully captured by this metric. In this way, I extract universal features across seemingly very different models. This further motivates a reorganisation of the dynamics around zeroes of the Fisher metric, corresponding to extrema of the probability distribution. Concretely, I propose a simple form of the metric for which I analytically solve the dynamics of the system that well approximates the time evolution of various established models in epidemiology and population dynamics, thus providing a unifying framework.

Quantum & Crémant: Exploring the mysteries of metalloenzymes in mushrooms with quantum chemistry
Speaker: Erik Donovan Hedegård Department of Physics, Chemistry and Pharmacy University of Southern Denmark Abstract: Transition metals in biological systems pose a formidable challenge in modern quantum chemistry. Unfortunately, these metals are close to everywhere in biological systems. For instance, about one-third of all enzymes contain a transition metal. The main issues when dealing with transition metals are (i) the metal typically demands so-called complete active space (CAS) methods with billions of electron configurations included. This quickly becomes computationally costly. (ii) Relativistic effects can be sizable. Addressing these effects also becomes computationally demanding. (iii) The relevant chemistry usually occurs in a surrounding solvent or within a protein environment that also needs to be taken into account, both in terms of the nuclear dynamics as well as the electronic interactions between the metal and the environment. In this talk, we demonstrate how challenges (i)–(iii) can be tackled efficiently and accurately. We discuss how this allows us to understand a part of the global carbon cycle, enzymes that can boost the production of biofuel, and new drugs against cancer. Location: D-IAS Aud.

QM Introductory Seminar: Supermanifolds, Super Riemann surface, and supermoduli space
Speaker: Nadia Ott (University of Southern Denmark) Abstract: I will give an introductory talk on supermanifolds, super Riemann surfaces, and supermoduli space, starting with the definitions of these objects. I will then introduce a current area of research in supergeometry, super period matrices, and state two famous results in the field: Donagi and Witten’s proof that supermoduli space is not split for genus g ≥ 5, and D’Hoker and Phong’s calculation of the genus g = 2 superstring amplitude.
QM Research Seminar: Periods on super Riemann surfaces
Speaker: Nadia Ott (University of Southern Denmark) Abstract: D’Hoker and Phong’s calculation of the genus g = 2 superstring amplitude uses, in a crucial way, a projection from genus g = 2 supermoduli space to its underlying reduced space. They define this projection using a formula for the genus g = 2 super period matrix. Witten generalized their formula for the super period matrix to higher genus g and found that the super period matrix may develop a pole along a particular divisor in supermoduli space if g ≥ 11. This divisor is commonly called the bad divisor. Witten also considered super period matrices on super Riemann surfaces with a nonzero number of Ramond punctures (note: the word puncture is a bit of a misnomer). He found that in the presence of Ramond punctures, a closed one form has, in addition to the usual 2g ”even” periods (defined by integrals over one cycle in homology), 2r fermionic periods. The fermionic periods of one form w are certain constants appearing in the restriction of w to the Ramond divisor. In joint work with Ron Donagi, we identify the 2r fermionic periods of w with the residues of a particular global section of the twisted spin structure on the underlying curve. As in the unpunctured case, the super period matrix with Ramond punctures may develop a singularities as we vary over supermoduli space. Using this identification of the fermionic periods in terms of residues, we explicitly describe this bad locus in supermoduli space.

QM Research Seminar: Supermoduli Space with Ramond punctures is not projected
Speaker: Ron Donagi (University of Pennsylvania) Abstract: After a brief review of the background on super geometry and of Super Riemann surfaces and their punctures, I will discuss the proof (with Witten) that the supermoduli space of super Riemann surfaces is not projected for g ≥5, and the more recent proof, with Ott, that the supermoduli space Mg,0,2r of super Riemann Surfaces with Ramond punctures is also not projected, for all g≥5r+1 and r≥6.
