The electronic structure and optical properties of Ca3(Mn1−xTix)2O7from first-principle calculations [PDF]

open access: yesJournal of Advanced Dielectrics, 2019
The electronic structure and optical properties of Ca3(Mn1−xTix)2O7 (x=0, 1/8, 2/8, 3/8, 4/8) were studied by first-principle calculations within the generalized gradient approximation approaches (GGA).

Fast algorithm to calculate density of states [PDF]

open access: yesPhysical Review E, 2007
An algorithm to calculate the density of states, based on the well-known Wang-Landau method, is introduced. Independent random walks are performed in different restricted ranges of energy, and the resultant density of states is modified by a function of time, F(t)=1/t, for large time.

Spatial structure of an incompressible Quantum Hall strip

open access: yes, 1999
The incompressible Quantum Hall strip is sensitive to charging of localized states in the cyclotron gap. We study the effect of localized states by a density functional approach and find electron density and the strip width as a function of the density ...

Investigation on nickel ferrite nanowire device exhibiting negative differential resistance — a first-principles investigation

open access: yesCondensed Matter Physics, 2017
The electronic property of NiFe_2O_4 nanowire device is investigated through nonequilibrium Green’s functions (NEGF) in combination with density functional theory (DFT).

Energy density of variational states

open access: yes, 2014
We show, in several important and general cases, that a low variational energy density of a trial state is possible even when the trial state represents a different phase from the ground state. Specifically, we ask whether the ground state energy density

Density of states in spectral geometry

open access: yesCommentarii Mathematici Helvetici, 1993
It is well known that the concept of integrated density of states was introduced by physicists in quantum theory of solids. In the paper under review a geometrical formalization of this notion is proposed and for the particular case of the manifolds with compact quotient some necessary and sufficient conditions for its existence are pointed out.

High-Precision Thermodynamics and Hagedorn Density of States

open access: yes, 2009
We compute the entropy density of the confined phase of QCD without quarks on the lattice to very high accuracy. The results are compared to the entropy density of free glueballs, where we include all the known glueball states below the two-particle ...

Influence of intrinsic point defects and substitutional impurities (Cl, I-S) on the electronic structure of 2H-SnS2

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2018
It was performed the systematic investigation of chemical modification regularities of electronic structure at the composition changes of “ideal” 2H-SnS 2 crystal by using the self-consistent density functional theory method in the supercell model.
