Research (S.R.Dahmen, 2019)






Overview


My research has always been focused on a specific modus operandi rather than on a specific theme: trying to find links between seemingly uncorrelated areas and using methods of one to explain the other. I became interested in this kind of approach during my Master, when I studied how Conformal Field Theory could be used to determine the operator content of exactly integrable spin models of Statistical Mechanics. Later, during my PhD, I worked on mappings of SU(p/q)-invariant (integrable) models to reaction-diffusion processes and crystal growth. I am also interested in History of Science and have published a few papers on this particular topic.

During my career I have also published a few experimental papers, an article on prime-number theory and several annotated translations from German and English into Portuguese. My interest in the popularization of science led me to writing articles for the general (non scientific) public, published in newspapers and magazines. The most extensive newspaper article was the one published in 2015 in the German Frankfurter Allgemeine Zeitung, which is related to the work I am doing now on networks and history (a link to this article can be found in the homepage under the acronym FAZ). I have also published several articles for undergraduate students in the Revista Brasileira de Ensino de Física (Brazilian Journal of Physics Teaching).




Temporal Network Theory


My research in this field has been conducted in collaboration with Ana Bazzan (Computer Science, Porto Alegre), Sandra Prado (Physics, Porto Alegre), Ralph Kenna and Pádraig Mac Carron (Physics, Coventry and Maynooth), Julia Hillner and Maírín Mac Carron (History, Sheffield and Dublin) and Robert Gramsch-Stehfest (Jena). The idea is to provide historians with techniques they can use and gain new insights into historical events. The work done with Robert Gramsch-Stehfest and Ana Bazzan was that of finding coalitions of sovereigns during the crisis of the Holy Roman Empire of German Nations in 1225. The ongoing project with Julia and Maírín is on networks of women during the Late Roman Empire and early Middle Ages. This project is supported by the Leverhulme Foundation. I am also studying networks of scientists in a project with Giuditta Parolini of the Technische Universität Berlin (TU-Berlin).



History of Science


I wrote an extensive article on the Physics and Mathematics of Denis Diderot. I am currently studying Bede's De Temporum Ratione and related literature on time reckoning.
