Route to form skyrmions in soft magnetic films
(American Institute of Physics, 2019-08)
Magnetic skyrmions which are topologically nontrivial magnetization configurations have attracted much attention recently due to their potential applications in information recording and signal processing. Conventionally, ...
Two-color XUV plus NIR femtosecond photoionization of neon in the near-threshold region
(IOP Publishing, 2019-06-28)
Results of angle-resolved electron spectroscopy of near-threshold photoionization of Ne atoms by combined femtosecond extreme ultraviolet and near infrared fields are presented. The dressed-electron spectra show an energetic ...
Possible experimental realization of a basicZ2topological semimetal in GaGeTe
(American Institute of Physics, 2019-12-01)
We report experimental and theoretical evidence that GaGeTe is a basic Z(2) topological semimetal with three types of charge carriers: bulk-originated electrons and holes as well as surface state electrons. This electronic ...
Surface state tunable energy and mass renormalization from homothetic quantum dot arrays
(Royal Society of Chemistry, 2019-12-28)
Quantum dot arrays in the form of molecular nanoporous networks are renowned for modifying the electronic surface properties through quantum confinement. Here we show that, compared to the pristine surface state, the band ...
Synthesis of macrocyclic poly(ethylene oxide)s containing a protected thiol group: a strategy for decorating gold surfaces with ring polymers
(Royal Society of Chemistry, 2019-12-21)
We introduce an approach to synthesize macrocyclic poly(ethylene oxide)s containing a pendant protected thiol group (pSH-CPEO), which is demonstrated to be able to attach to gold surfaces without prior deprotection. Our ...
Non-Abelian anomalies and hadronic fluids
By using differential geometry methods, we study the role of non-Abelian anomalies in relativistic fluids. We obtain closed expressions for the covariant currents derived from the Chern-Simons effective action. Our results ...
First principles simulations of sodium-based battery materials.
Las baterías de sodio son un grupo prometedor de dispositivos de almacenamiento de energía eléctrica para aplicaciones donde el peso y volumen de la batería no es tan importante, por ejemplo en baterías estacionarias para ...
Equilibrium and transport properties of hybrid junctions between superconductors and spin active materials
En esta tesis investigamos la evolución del estado singlete de un material superconductor convencional debido a campos dependientes del espín a su alrededor.
Transport and spectral properties of low-dimensional superconductors in the presence of spin-dependent fields.
he interplay between superconductivity and spin-dependent fields is known to lead to striking phenomena, like critical field enhancement, magnetoelectric effects and the appearance of Yu-Shiba-Rusinov bound states at ...
Impact of Stress Annealing on the Magnetization Process of Amorphous and Nanocrystalline Co-Based Microwires
The domain wall (DW) dynamics of amorphous and nanocrystalline Co-based glass-coated microwires are explored under the influence of stress annealing. Different annealing profiles have enabled remarkable changes in coercivity ...
