Spin density wave instabilities in the NbS2 monolayer
(American Physical Society, 2016-03)
In the present work, we study the magnetic properties of the NbS2 monolayer by first-principles calculations. The transition metal dichalcogenides (TMDCs) are a family of laminar materials presenting exciting properties ...
Competition between spin-induced charge instabilities in underdoped cuprates
(American Physical Society, 2018-12)
We study the static charge correlation function in a one-band model on a square lattice. The Hamiltonian consists of effective hoppings of the electrons between the lattice sites and the Heisenberg Hamiltonian. Approximating ...
Noncollinear spin-spiral phase for the uniform electron gas within reduced-density-matrix-functional theory
(American Physical Society, 2010-01)
The noncollinear spin-spiral density wave of the uniform electron gas is studied in the framework of reduced-density-matrix-functional theory. For the Hartree-Fock approximation, which can be obtained as a limiting case ...
Dependence of shear wave seismoelectrics on soil textures: A numerical study in the vadose zone
(Wiley Blackwell Publishing, Inc, 2017-02)
In this work, we study seismoelectric conversions generated in the vadose zone, when this region is traversed by a pure SH wave. We assume that the soil is a 1-D partially saturated lossy porous medium and we use the van ...
Holographic p-wave Superconductor with Disorder
(Springer, 2015-07)
We implement the effects of disorder on a holographic p-wave superconductor by introducing a random chemical potential which defines the local energy of the charge carriers. Since there are various possibilities for the ...
Stopping power of cluster ions in a free-electron gas from partial-wave analysis
(American Physical Society, 2018-12)
A nonlinear model for the stopping power of cluster ions based on partial-wave analysis is developed through the generalization of the induced density approach (IDA) model for the interaction of homo- and heteronuclear ...
Gravito-magnetic monopoles in traversable wormholes from WIMT
(Elsevier, 2017-03)
Using Weitzenböck Induced Matter Theory (WIMT), we study Schwarzschild wormholes performing different foliations on an extended (non-vacuum) 5D manifold. We explore the geodesic equations for observers which are in the ...
Low intensity, continuous wave photodoping of ZnO quantum dots - Photon energy and particle size effects
(Royal Society of Chemistry, 2017-01)
The unique properties of semiconductor quantum dots (QDs) have found application in the conversion of solar to chemical energy. How the relative rates of the redox processes that control QD photon efficiencies depend on ...
Electronic structure of the double perovskite Ba2Er(Nb,Sb)O 6
(IOP Publishing, 2014-04)
In this work, we present a detailed study of the structural and the electronic structure of the double perovskite Ba2Er(Nb,Sb)O 6. All calculations were performed with the Full-Potential Linear Augmented Plane Wave method ...
Phase diagram of the asymmetric Hubbard model and an entropic chromatographic method for cooling cold fermions in optical lattices
(American Physical Society, 2012-08)
We study the phase diagram of the asymmetric Hubbard model (AHM), which is characterized by different values of the hopping for the two spin projections of a fermion or, equivalently, two different orbitals. This model is ...
