Abstract
The data science revolution is finally enabling the development of large-scale data-driven models that provide real- or near-real-time forecasts and risk analysis for infectious disease threats. These models also provide rationales and quantitative analysis to support policy making decisions and intervention plans. At the same time, the non-incremental advance of the field presents a broad range challenges: algorithmic (multiscale constitutive equations, scalability, parallelization), real time integration of novel digital data stream (social networks, participatory platform, human mobility etc.). I will review and discuss recent results and challenges in the area, and focus on ongoing work aimed at responding to the COVID-19 pandemic.

Two #PhD Positions in Experimental Condensed Matter Physics (f/m/d)
https://bit.ly/2ylYfIS

JOB DESCRIPTION
(part-time 75%, E 13 TV-L)
Two doctoral positions are available in the research field of superconducting spintronics and superconducting devices for technological applications. The research projects focus on combining superconductor and ferromagnet materials to fabricate electronic devices with high energy efficiency for large data centers and quantum technology applications. The doctoral positions are funded by the Alexander von Humboldt Foundation through a Sofja Kovalevskaja research grant and by the DFG SPP2244 program “2D Materials – Physics of van der Waals [hetero]structures (2DMP)”, respectively. The research has a strong interdisciplinary focus, at the intersection between materials science, condensed matter physics and low-temperature physics. The working language is English.

The effect of social balance on social fragmentation

Tuan Minh Pham, Imre Kondor, Rudolf Hanel, Stefan Thurner

Download PDF

With the availability of cell phones, internet, social media etc. the interconnectedness of people within most societies has increased drastically over the past three decades. Across the same timespan, we are observing the phenomenon of increasing levels of fragmentation in society into relatively small and isolated groups that have been termed filter bubbles, or echo chambers. These pose a number of threats to open societies, in particular, a radicalisation in political, social or cultural issues, and a limited access to facts. In this paper we show that these two phenomena might be tightly related. We study a simple stochastic co-evolutionary model of a society of interacting people. People are not only able to update their opinions within their social context, but can also update their social links from collaborative to hostile, and vice versa. The latter is implemented such that social balance is realised. We find that there exists a critical level of interconnectedness, above which society fragments into small sub-communities that are positively linked within and hostile towards other groups. We argue that the existence of a critical communication density is a universal phenomenon in all societies that exhibit social balance. The necessity arises from the underlying mathematical structure of a phase transition phenomenon that is known from the theory of a kind of disordered magnets called spin glasses. We discuss the consequences of this phase transition for social fragmentation in society.
