Creating stable Floquet–Weyl semimetals by laser-driving of 3D Dirac materials
(Nature Publishing, 2017-01-17)Tuning and stabilizing topological states, such as Weyl semimetals, Dirac semimetals or topological insulators, is emerging as one of the major topics in materials science. Periodic driving of many-body systems offers a ... -
Crowded Solutions of Single-Chain Nanoparticles under Shear Flow
(Royal Society Of Chemistry, 2021-03-04)Single-chain nanoparticles (SCNPs) are ultrasoft objects obtained through purely intramolecular cross-linking of single polymer chains. By means of computer simulations with implemented hydrodynamic interactions, we ... -
Defect and structural imperfection effects on the electronic properties of BiTeI surfaces
(IOP Publishing, 2014-07-24)The surface electronic structure of the narrow-gap seminconductor BiTeI exhibits a large Rashba-splitting which strongly depends on the surface termination. Here we report on a detailed investigation of the surface morphology ... -
Development of Magnetic Microwires for Magnetic Sensor Applications
Zhukova Zhukova, Valentina; Corte León, Paula ; ; Blanco Aranguren, Juan María ; González Legarreta, Lorena; Zhukov Egorova, Arkady Pavlovich (MDPI, 2019-11-02)
Thin magnetic wires can present excellent soft magnetic properties (with coercivities up to 4 A/m), Giant Magneto-impedance effect, GMI, or rectangular hysteresis loops combined with quite fast domain wall, DW, propagation. ... -
Direct Observation of Desorption of a Melt of Long Polymer Chains
(Nature, 2020-08-28)Tuning the thermodynamic state of a material has a tremendous impact on its performance. In the case of polymers placed in proximity of a solid wall, this is possible by annealing above the glass transition temperature, ... -
Divalent EuRh2Si2 as a Reference for the Luttinger Theorem and Antiferromagnetism in Trivalent Heavy-Fermion YbRh2Si2
(Nature Publishing Group, 2019-02-15)Application of the Luttinger theorem to the Kondo lattice YbRh2Si2 suggests that its large 4f derived Fermi surface (FS) in the paramagnetic (PM) regime should be similar in shape and volume to that of the divalent ... -
Domain wall dynamics of magnetically bistable microwires
