This is the first time in the 51-year history of the IFF Spring School that the subject has been a “Technology”. Can there be two weeks of intensive lectures by top scientists on a mere technology? The decision just a few years ago, to designate $\textbf{Quantum Technology}$ as a coherent societal endeavour, was taken after much deliberation within a large circle of working scientists [...]

Topology and entanglement are key concepts in many-body physics. Understanding the as-sociated emergent phenomena beyond toy models – in the world of real strongly-correlatedmaterials – requires the mastery of a wealth of different methods. [...]

This paper addresses the issue of social inequality by comparing German household data (gross income, Food‐Energy‐(Watervirtual)‐Nexus expenditures) from2008 and 2013. The distribution of gross income and of the FE(Wvirtual)‐Nexus related consumption expenditures based on this income is analysed using a three stepapproach: First, the real distribution is determined, secondly, the dispersion (based on Rawls’ philosophical concept) is analysed, and finally, the normativedistribution according to the Atkinson index is calculated to reveal a view on social inequality.

On February 27 and 28, 2020 computational scientists will present their exciting research results at the 10$^{th}$ NIC symposium in Jülich. About 20 years after the first NIC symposium on December 5 and 6, 2001, this series of biannual meetings has established a valued tradition, highlighting a diverse range of some of the best, modern, computational science at the von Neumann Institute for Computing (NIC) [...]

We present the most recent solar neutrino results from the Borexino experiment at the Gran Sasso underground laboratory. In particular, refined measurements of all neutrinos produced in the pp fusion chain have been made. [...]

In more than ten years of operation, Borexino has performed a precision measurement of the solar neutrino spectrum, resolving almost all spectral components originating from the proton-proton fusion chain. The presentation will review the results recently released for the second data taking phase 2012–2016 during which the detector excelled by its unprecedentedly low background levels. [...]

The possibility of a non-zero neutrino magnetic moment has been checked using Borexino Phase-II solar neutrino data. The expected signal considered in the analysis is a contribution to the neutrino-electron scattering cross section induced by electromagnetic interactions. [...]

Liquid-scintillator based neutrino detection is a well established experimental technique of neutrino spectroscopy. Thanks to a high light yield of liquid scintillators, detection of even sub-MeV neutrinos is possible with a good energy and position reconstruction resolution. [...]
