Quasiparticles called merons appear in a synthetic antiferromagnet for the first time
Collective topological chiral spin textures could lead to new concepts for spintronics devices
"When compared with conventional metals, shot noise in these #nanowires is strongly suppressed. This suppression cannot be attributed to either electron-phonon or electron-electron interactions in a #Fermi liquid, which suggests that the current is not carried by well-defined #quasiparticles in the strange-metal regime that we probed. Our work sets the stage for similar studies of other strange metals."
Waves of Entanglement Seen Rippling Through a #QuantumMagnet For The First Time

Crafting organic molecules into a bizarre kind of magnet, physicists from Aalto University and the University of Jyväskylä in Finland have created the perfect space for observing the elusive activity of an electronic state called a triplon.
Researchers @HZDR, Max Planck Institute for Chemical Physics of Solids, the Leibniz Institute for Solid State and Materials Research Dresden, and the University of South Florida used an ion beam saw and sophisticated measurement techniques on the quest to detect special #quasiparticles called #antiskyrmions, as they report:

Skyrmions are microscopic magnetic vortices that can form in certain materials. First detected in 2009, they are of interest to research because they could be harnessed for new forms of data storage. As theoreticians had predicted, there are also so called antiskyrmions, which were eventually discovered ten years after skyrmions. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Max Planck Institute for Chemical Physics of Solids, the Leibniz Institute for Solid State and Materials Research Dresden, and the University of South Florida used an ion beam saw and sophisticated measurement techniques to get to the bottom of this complex phenomenon, as they report in the journal Communications Materials (https://doi.org/10.1038/s43246-022-00323-6).
A definitive discovery of #Majorana #quasiparticles would bring the potential of #topological #quantum #computing closer to reality.
In the original proposals, the “recipe” for observing Majoranas experimentally appeared deceptively simple. In the intervening years, it has become clear that the real world is more complicated than the models predicted, and Majoranas remain elusive.
