Current-induced nucleation and dynamics of skyrmions in a Co-based Heusler alloy
W. Akhtar, A. Hrabec, S. Chouaieb +9
We demonstrate room-temperature stabilization of dipolar magnetic skyrmions with diameters in the range of nm in a single ultrathin layer of the Heusler alloy CoFeAl (CFA…
Fundamental limits for non-destructive measurement of a single spin by Faraday rotation
Denis Scalbert
Faraday rotation being a dispersive effect, is commonly considered as the method of choice for non-destructive detection of spin states. Nevertheless Faraday rotation is inevitably…
Excitonic emission in van-der-Waals nanotubes of transition metal dichalcogenides
T. V. Shubina, M. Remškar, V. Yu. Davydov +3
Nanotubes (NTs) of transition metal dichalcogenides (TMDs), such as MoS2 and WS2, were first synthesized more than a quarter of a century ago; nevertheless, many of their propertie…
Sound attenuation in stable glasses
Lijin Wang, Ludovic Berthier, Elijah Flenner +2
Understanding the difference between universal low-temperature properties of amorphous and crystalline solids requires an explanation of the stronger damping of long-wavelength pho…
Effective approach to lepton observables: the seesaw case
Rupert Coy, Michele Frigerio
In the absence of direct evidence of new physics, any ultraviolet theory can be reduced to its specific set of low-energy effective operators. As a case study, we derive the effect…
Hybridization of topological surface states with a flat band
Sergey S. Krishtopenko, Mauro Antezza, Frédéric Teppe
We address the problem of hybridization between topological surface states and a non-topological flat bulk band. Our model, being a mixture of three-dimensional Bernevig-Hughes-Zha…
