Excitons are being explored in materials science and information technology as a means of storing light. These luminous quasiparticles move through individual layers of quantum materials and can absorb and emit light with high efficiency. They form when a laser pulse excites an electron, leaving behind a positively charged \u201chole.\u201d The electron and hole attract each other and behave together like a new, independent particle. When the quasiparticle recombines, it emits light and can be detected in high-tech laboratories.<\/p>\n

Excitons in ultrathin quantum materials have been intensively studied for more than a decade, including by Alexey Chernikov and his team. At the Cluster of Excellence ctd.qmat\u2014Complexity, Topology and Dynamics in Quantum Matter\u2014at the Universities of W\u00fcrzburg and Dresden, Chernikov and an international research team based in Dresden have now made a surprising discovery: excitons can be carried along by the magnetic excitations<\/a> of a quantum material and, as a result, accelerated to ultrahigh speeds. The findings are published<\/a> in the journal Nature Nanotechnology.<\/p>\n

\u201cThe fact that the motion of optical particles can be controlled by magnetism is new. Until now, we only knew that the transport of electrons could be controlled by the magnetic order in a quantum material\u2014this is how some sensors in smartphones work, for example. This newly discovered link between optics and magnetism could open up entirely new technological possibilities,\u201d explains Florian Dirnberger, head of an Emmy Noether Junior Research Group at the Technical University of Munich and formerly a postdoctoral researcher in Alexey Chernikov\u2019s Chair of Ultrafast Microscopy and Photonics, where he was responsible for carrying out the research project.<\/p>\n","protected":false},"excerpt":{"rendered":"
