Graphene/MoS2 heterostructures as templates for growing two-dimensional metals: Predictions from ab initio calculations
(Physical Review Materials, 2017)
Preparation of single-atom-thick layers of ordinary metals has been a challenging task since their closely packed atoms lack layered structure with highly anisotropic bonding. Using computational modeling based on density ...
Similarity of structure properties of Hg1-xMnxS and Cd1-xMnxS (structure properties of HgMnS and CdMnS)
(Journal of Magnetism and Magnetic Materials, 1996)
We report the structural parameters and their variation with manganese concentration for the diluted magnetic semiconductors Hg1-xMnxS (x less than or equal to 0.33) and Cd1-xMnxS (x less than or equal to 0.43), as obtained ...
The influence of the interchain coupling on large acoustic polarons in coupled molecular chains: Three coplanar parallel molecular chains
(Chaos, Solitons and Fractals, 2015)
We study the properties of the single large adiabatic polaron in the substances composed of three parallel equally separated coplanar molecular chains. Particular attention has been devoted to the influence of the interchain ...
Finite-temperature two-state small-polaron dynamics: Averaged Hamiltonian approach
(Journal of Physics: Condensed Matter, 1996)
We study small-polaron self-trapping properties in the two-state molecular crystal model by employing a finite-temperature variational non-adiabatic approach that is an extension to the semiclassical adiabatic Pekar theory. ...
Kinetic properties of multiquanta Davydov-like solitons in molecular chains
(Physical Review E, 1999)
The Fokker-Planck equation for multivibron solitons interacting with lattice vibrations in a molecular chain has been derived by means of the nonequilibrium statistical operator method. It was shown that a soliton undergoes ...
Self-induced transparency of the optical phonons
(Chaos, Solitons and Fractals, 2017)
We show that the self-induced transparency of optical phonons may appear in a systems consisting of a two level atoms interacting with elastic waves. The presence of the gap in phonon spectrum substantially enhances the ...
Addressing the missing matter problem in galaxies through a new fundamental gravitational radius
(Journal of Cosmology and Astroparticle Physics, 2017)
We demonstrate that the existence of a Noether symmetry in f theories of gravity gives rise to a further gravitational radius, besides tile standard Schwarzschild one, determining the dynamics at galactic scales. By this ...
Devils staircase and the absence of chaos in the dc- and ac-driven overdamped Frenkel-Kontorova model
(Physical Review E, 2017)
The devils staircase structure arising from the complete mode locking of an entirely nonchaotic system, the overdamped dc+ac driven Frenkel-Kontorova model with deformable substrate potential, was observed. Even though no ...
Analytical modeling of electron energy loss spectroscopy of graphene: Ab initio study versus extended hydrodynamic model
(Ultramicroscopy, 2018)
We present an analytical modeling of the electron energy loss (EEL) spectroscopy data for free-standing graphene obtained by scanning transmission electron microscope. The probability density for energy loss of fast electrons ...
Crystal structures, magnetic properties and DFT study of cobalt(II) azido complexes with the condensation product of 2-quinolinecarboxaldehyde and Girards T reagent
(Polyhedron, 2018)
A tridentate NNO condensation product of 2-quinolinecarboxaldehyde and Girards T reagent (HLC1) in the presence of azide ions coordinates with cobalt(II) giving mononuclear azido Co(II) complex [CoHL (N-3)(3)](1) as a main ...
