Theoretical model for Rashba spin-orbit interaction in d electrons
(Physical Review B: Condensed Matter and Materials Physics, 2014)
We show that the Rashba spin-orbit interaction in d electron solids, which originates from the broken inversion symmetry at surfaces or interfaces, is strongly dependent on the orbital characters of the bands involved. ...
Nonlinear localized flat-band modes with spin-orbit coupling
(Physical Review B: Condensed Matter and Materials Physics, 2016)
We report the coexistence and properties of stable compact localized states (CLSs) and discrete solitons (DSs) for nonlinear spinor waves on a flat-band network with spin-orbit coupling (SOC). The system can be implemented ...
Critical behavior of the van derWaals bonded ferromagnet Fe3-xGeTe2
(Physical Review B: Condensed Matter and Materials Physics, 2017)
The critical properties of the single-crystalline van der Waals bonded ferromagnet Fe3-xGeTe2 were investigated by bulk dc magnetization around the paramagnetic to ferromagnetic (FM) phase transition. The Fe3-xGeTe2 single ...
Modulation instability in two-dimensional nonlinear Schrodinger lattice models with dispersion and long-range interactions
(Physical Review B: Condensed Matter and Materials Physics, 2003)
The problem of modulation instability of continuous wave and array soliton solutions within the framework of a two-dimensional continuum-discrete nonlinear Schrodinger lattice model, which accounts for dispersion and ...
Ab initio study of the electron energy loss function in a graphene-sapphire-graphene composite system
(Physical Review B: Condensed Matter and Materials Physics, 2017)
The propagator of a dynamically screened Coulomb interaction W in a sandwichlike structure consisting of two graphene layers separated by a slab of Al2O3 (or vacuum) is derived from single-layer graphene response functions ...
Critical current density and vortex pinning in tetragonal FeS1-xSex (x=0,0.06)
(Physical Review B: Condensed Matter and Materials Physics, 2016)
We report critical current density (J(c)) in tetragonal FeS single crystals, similar to iron-based superconductors with much higher superconducting critical temperatures (T-c). The Jc is enhanced three times by 6% Se doping. ...
Adsorption sites of individual metal atoms on ultrathin MgO(100) films
(Physical Review B: Condensed Matter and Materials Physics, 2017)
We use Ca doping during growth of one-and two-monolayer-thick MgO films on Ag(100) to identify the adsorption sites of individual adatoms with scanning tunneling microscopy. For this we combine atomic resolution images of ...
Density functional study of the insulating ground states in CaFeO3 and La1/3Sr2/3FeO3 compounds
(Physical Review B: Condensed Matter and Materials Physics, 2005)
The origin of the insulating ground states and the charge disproportionation in the two Fe-based perovskite oxides, viz., CaFeO3 and La1/3Sr2/3FeO3, are examined from ab initio electronic structure calculations based on ...
Observation of Dirac-like band dispersion in LaAgSb2
(Physical Review B: Condensed Matter and Materials Physics, 2016)
We present a combined angle-resolved photoemission spectroscopy (ARPES) and first-principles calculations study of the electronic structure of LaAgSb2 in the entire first Brillouin zone. We observe a Dirac-cone-like structure ...
Dimensional mismatch of the electron-phonon system and large polaron stability
(Physical Review B: Condensed Matter and Materials Physics, 2005)
We consider the scaling arguments in the adiabatic limit for materials in which one-dimensional (1D) electronic behavior is influenced by a higher-dimensional vibrational system. The system under consideration consists of ...
