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 ...
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 ...
Development of Magnetic Microwires for Magnetic Sensor Applications
(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. ...
Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides
(Nature, 2019-07-29)
Chalcogen vacancies are generally considered to be the most common point defects in transition metal dichalcogenide (TMD) semiconductors because of their low formation energy in vacuum and their frequent observation in ...
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 ...
Non-Abelian anomalies and hadronic fluids
(IOP, 2019)
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 ...
Soft Magnetic Amorphous Microwires for Stress and Temperature Sensory Applications
(MDPI, 2019-12)
Amorphous ferromagnetic materials in the form of microwires are of interest for the development of various sensors. This paper analyzes and argues for the use of microwires of two basic compositions of Co71Fe5B11Si10Cr3 ...
Glass-Transition Dynamics of Mixtures of Linear Poly(Vinyl Methyl Ether) with Single-Chain Polymer Nanoparticles: Evidence of a New Type of Nanocomposite Materials
(MDPI, 2019-03-21)
Single-chain polymer nanoparticles (SCNPs) obtained through chain collapse by intramolecular cross-linking are attracting increasing interest as components of all-polymer nanocomposites, among other applications. We present ...
Motions of Water and Solutes-Slaving Versus Plasticization Phenomena
(American Institute of Physics, 2019-03-28)
It is well-accepted that hydration water is crucial for the structure, dynamics, and function of proteins. However, the exact role of water for the motions and functions of proteins is still debated. Experiments have shown ...
Orbital magneto-optical response of periodic insulators from first principles
(Springer, 2019-03-06)
Magneto-optical response, i.e. optical response in the presence of a magnetic field, is commonly used for characterization of materials and in optical communications. However, quantum mechanical description of electric and ...
