Gibbs Energy of Mixing Function: Topological Analysis in Azeotropic Systems

ESAT 2014. 27th European Symposium on Applied Thermodynamics, Eindhoven University of Technology, July 6-9, 2014.

Topological spin waves in the atomic-scale magnetic skyrmion crystal

We study the spin waves of the triangular skyrmion crystal that emerges in a two-dimensional spin lattice model as a result of the competition between Heisenberg exchange, Dzyalonshinkii–Moriya interactions, Zeeman coupling and uniaxial anisotropy. The calculated spin wave bands have a finite Berry curvature that, in some cases, leads to non-zero Chern numbers, making this system topologically distinct from conventional magnonic systems. We compute the edge spin-waves, expected from the bulk-boundary correspondence principle, and show that they are chiral, which makes them immune to elastic backscattering. Our results illustrate how topological phases can occur in self-generated emergent superlattices at the mesoscale.

Antitrust on the ‘G string’: What’s behind the Commission’s investigations of Google and Gazprom? CEPS Commentary, 15 June 2015

The past few weeks have marked a shift of gear in EU antitrust enforcement. First, the new European Commissioner for Competition Margarethe Vestager announced on April 15th that the Commission had sent a Statement of Objections to Google, arguing that the giant IT company abused its dominant position in the “general Internet search” market and also in the market for mobile operating systems, apps and services. Exactly one week later, she also sent a Statement of Objections to Gazprom for having created artificial barriers to trade between certain EU countries, preventing gas flows and competition across national borders and charging unfair prices in five Central and Eastern European countries. It is indeed hard to recall any other time in which two investigations of this size – both potentially leading to billions of euros of fines – have been launched almost simultaneously.
