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."

The seemingly physics-defying properties of #quasiparticles could be harnessed for applications ranging from non-destructive #imaging to #computer chip manufacturing.

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:

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.

#Scientists have found the secret behind a property of solid materials known as #ferroelectrics, showing that #quasiparticles moving in wave-like patterns among vibrating #atoms carry enough heat to turn the material into a thermal switch when an #electrical field is applied externally.

I've just been watching Matt O'Dowd talk abot #quasiparticles.

There are quasi-analogues for fermions and bosons. Remember, fermions cannot occupy the same state, while you can stuff as many bosons in one place as you like.
