i ct.qmat 23 Der Doktorand Adam McRoberts ist aus Schottland extra nach Dresden gekommen, um am Max-PlanckInstitut für Physik komplexer Systeme bei Roderich Moessner zu promovieren. Er erforscht die Quantentheorie von Magneten. PhD student Adam McRoberts came all the way from Scotland to Dresden to do his doctorate under Roderich Moessner at the Max-Planck-Institut für Physik komplexer Systeme. He’s researching the quantum theory of magnets. # Pure research for unknown applications: ct.qmat is searching for strange states of matter known as “spin liquids.” The tools for this are provided by chemistry as well as theoretical and experimental physics. One candidate is ruthenium trichloride, RuCl3. #Grundlagenforschung für Anwendungen, die man noch nicht kennt: Im Exzellenzcluster wird nach seltsamen Materiezuständen gefahndet, sogenannten Spinflüssigkeiten. Chemie, theoretische und experimentelle Physik liefern das Werkzeug. Ein Kandidat ist Rutheniumtrichlorid, RuCl3. Basic research enables us to create tools that didn’t exist before,” declares Moessner – which is ultimately the objective of ct.qmat. With spin liquids, he explains, the aim is to “realize a state of matter that reacts differently from known magnets, and whose magnetic properties can be controlled.” Perhaps this could be used to generate, say, an alternating magnetic current – although this is only speculative, he adds. “Our current focus is to determine the laws by which such complex physical systems organize themselves.” Fermionen Fermions ... sind eine Teilchensorte, aus denen die Materie besteht, und wurden nach Enrico Fermi benannt. Dazu gehören unter anderem Elektronen und Neutrinos. Die Lichtteilchen – Photonen – dagegen sind Bosonen. ... are types of particles that make up matter. Named after Enrico Fermi, they include electrons and neutrinos. By contrast, light particles (photons) are bosons.
