Analysis of electronic structure and X-ray absorption and emission spectra in MgO within the FP-LAPW method
(Sciencedomain international, 2018-10-05)
In this work we calculated MgO ab initio X-ray Absorption and Emission spectra using the Full Potential Linearized Augmented Plane Wave method within the Density Functional Theory formalism. The X-ray Absorption and Emission ...
Enhanced pairing of quantum critical metals near d=3+1
(American Physical Society, 2015-07)
We study the dynamics of a quantum critical boson coupled to a Fermi surface in intermediate energy regimes where the Landau damping of the boson can be parametrically controlled, either via large Fermi velocity or by ...
Interference effects in the plasmon fields excited by a diatomic molecule
(Elsevier Science, 2015-07-01)
We study the fluctuations of the plasmon field associated to the wake potential generated by a dimer formed by two identical charged particles (such as two nuclei of the ionized hydrogen molecule) traveling through a ...
A global two-temperature corona and inner heliosphere model: A comprehensive validation study
(IOP Publishing, 2012-01)
The recent solar minimum with very low activity provides us a unique opportunity for validating solar wind models. During CR2077 (2008 November 20 through December 17), the number of sunspots was near the absolute minimum ...
The role of magnetic excitations in magnetoresistance and Hall effect of slightly TM-substituted BaFe2As2 compounds (TM = Mn, Cu, Ni)
(Elsevier Science, 2016-12-15)
We report on electrical resistivity, magnetoresistance (MR) and Hall effect measurements in four non-superconducting BaFe2−xTMxAs2 (TM = Mn, Cu and Ni) single crystals with small values of the chemical substitution x. The ...
Energy barriers between metastable states in first-order quantum phase transitions
(American Physical Society, 2018-02-05)
A system of neutral atoms trapped in an optical lattice and dispersively coupled to the field of an optical cavity can realize a variation of the Bose-Hubbard model with infinite-range interactions. This model exhibits a ...
Theoretical studies of doped solid oxides for fuel cell applications
(Bentham Science Publishers, 2014)
Uniaxial pressure control of competing orders in a high-temperature superconductor
(American Association for the Advancement of Science, 2018-11)
Cuprates exhibit antiferromagnetic, charge density wave (CDW), and high-temperature superconducting ground states that can be tuned by means of doping and external magnetic fields. However, disorder generated by these ...
Experimental and First-Principles Theoretical Study of Structural and Electronic Properties in Tantalum-Doped In2O3 Semiconductor: Finding a Definitive Hyperfine Interaction Assignment
(American Chemical Society, 2016-03)
In this work we present an experimental and theoretical study from first-principles of the structural, electronic, and hyperfine properties of Ta-doped In2O3 semiconductor. The ab initio electronic structure calculations ...
