      "summary_nl": "The question whether a superconductor in a magnetic field can support Landau levels is a celebrated problem in the context of d-wave superconductivity, with a negative answer: The scattering of the subgap excitations (Bogoliubov quasiparticles) by the magnetic vortex lattice destroys the Landau level quantization. We recently discovered that the same question has a positive answer for a Weyl superconductor: The chirality of the Weyl fermions protects the zeroth Landau level by means of a topological index theorem. The objective of this proposal is to demonstrate that the vortex lines in a Weyl superconductor form dissipationless conduction channels for Weyl fermions, allowing for transmission of heat and charge with a quantized thermal and electrical conductance - even in the presence of disorder.",

          "update_en": "The quantum Hall effect produces socalled \"flat bands\", known as Landau levels, in which the electrons have no kinetic energy. The aim of this project was to investigate the interplay of these flat bands with superconductivity. These two effects were considered to be incompatible, however, we have found that in certain systems they can coexist. The essential ingredient is the presence of massless electrons, such as found in graphene. A variety of interesting novel phenomena have been discovered theoretically, which can be observed in the laboratory.",
          "update_nl": "Het quantum-Hall-effect produceert zogenaamde \"vlakke banden\", bekend als Landau-niveaus, waarin de elektronen geen kinetische energie hebben. Het doel van dit project was om de wisselwerking van deze vlakke banden met supergeleiding te onderzoeken. Deze twee effecten werden als onverenigbaar beschouwd, maar we hebben ontdekt dat ze in bepaalde systemen naast elkaar kunnen bestaan. Het essentiële ingrediënt is de aanwezigheid van massaloze elektronen, zoals gevonden in grafeen. Er is een verscheidenheid van interessante nieuwe verschijnselen ontdekt, die in de toekomst in het laboratorium gemeten kunnen worden."
