text: The vibrational properties of stoichiometric LiNbO3 are analyzed within density-functional
perturbation theory in order to obtain the complete phonon dispersion of the material.
The phonon density of states of the ferroelectric (paraelectric) phase shows two
(one) distinct band gaps separating the high-frequency (~800 cm−1) optical branches
from the continuum of acoustic and lower optical phonon states. This result leads
to specific heat capacites in close agreement with experimental measurements in
the range 0–350 K and a Debye temperature of 574 K. The calculated zero-point
renormalization of the electronic Kohn–Sham eigenvalues reveals a strong dependence
on the phonon wave vectors, especially near Γ. Integrated over all phonon modes,
our results indicate a vibrational correction of the electronic band gap of 0.41 eV
at 0 K, which is in excellent agreement with the extrapolated temperature-dependent
measurements.

text: Using ab initio computational methods, we study the structural and electronic
properties of strained silicon, which has emerged as a promising technology to
improve the performance of silicon-based metal-oxide-semiconductor field-effect
transistors. In particular, higher electron mobilities are observed in n-doped
samples with monoclinic strain along the [110] direction, and experimental evidence
relates this to changes in the effective mass as well as the scattering rates.
To assess the relative importance of these two factors, we combine density-functional
theory in the local-density approximation with the GW approximation for the electronic
self-energy and investigate the effect of uniaxial and biaxial strains along the
[110] direction on the structural and electronic properties of Si. Longitudinal
and transverse components of the electron effective mass as a function of the
strain are derived from fits to the quasiparticle band structure and a diagonalization
of the full effective-mass tensor. The changes in the effective masses and the
energy splitting of the conduction-band valleys for uniaxial and biaxial strains
as well as their impact on the electron mobility are analyzed. The self-energy
corrections within GW lead to band gaps in excellent agreement with experimental
measurements and slightly larger effective masses than in the local-density approximation.

text: Collective spin excitations form a fundamental class of excitations in magnetic
materials. As their energy reaches down to only a few meV, they are present at
all temperatures and substantially influence the properties of magnetic systems.
To study the spin excitations in solids from first principles, we have developed
a computational scheme based on many-body perturbation theory within the full-potential
linearized augmented plane-wave (FLAPW) method. The main quantity of interest
is the dynamical transverse spin susceptibility or magnetic response function,
from which magnetic excitations, including single-particle spin-flip Stoner excitations
and collective spin-wave modes as well as their lifetimes, can be obtained. In
order to describe spin waves we include appropriate vertex corrections in the
form of a multiple-scattering T matrix, which describes the coupling of electrons
and holes with different spins. The electron–hole interaction incorporates the
screening of the many-body system within the random-phase approximation. To reduce
the numerical cost in evaluating the four-point T matrix, we exploit a transformation
to maximally localized Wannier functions that takes advantage of the short spatial
range of electronic correlation in the partially filled d or f orbitals of magnetic
materials. The theory and the implementation are discussed in detail. In particular,
we show how the magnetic response function can be evaluated for arbitrary k points.
This enables the calculation of smooth dispersion curves, allowing one to study
fine details in the k dependence of the spin-wave spectra. We also demonstrate
how spatial and time-reversal symmetry can be exploited to accelerate substantially
the computation of the four-point quantities. As an illustration, we present spin-wave
spectra and dispersions for the elementary ferromagnet bcc Fe, B2-type tetragonal
FeCo, and CrO2 calculated with our scheme. The results are in good agreement with
available experimental data.

text: Many-body perturbation theory is a well-established ab initio electronic-structure
method based on Green functions. Although computationally more demanding than
density functional theory, it has the distinct advantage that the exact expressions
for all relevant observables, including the ground-state total energy, in terms
of the Green function are known explicitly. The most important application, however,
lies in the calculation of excited states, whose energies correspond directly
to the poles of the Green function in the complex frequency plane. The accuracy
of results obtained within this framework is only limited by the choice of the
exchange-correlation self-energy, which must still be approximated in actual implementations.
In this respect, the GW approximation has proved highly successful for systems
governed by the Coulomb interaction. It yields band structures of solids, including
the band gaps of semiconductors, as well as atomic and molecular ionization energies
in very good quantitative agreement with experimental photoemission data.

text: We investigate the band dispersion and related electronic properties of picene
single crystals within the GW approximation for the electronic self-energy. The
width of the upper highest occupied molecular orbital (HOMOu) band along the Γ–Y
direction, corresponding to the b crystal axis in real space along which the molecules
are stacked, is determined to be 0.60 eV and thus 0.11 eV larger than the value
obtained from density-functional theory. As in our recent study of rubrene using
the same methodology [S. Yanagisawa, Y. Morikawa, and A. Schindlmayr, Phys. Rev.
B 88, 115438 (2013)], this increase in the bandwidth is due to the strong variation
of the GW self-energy correction across the Brillouin zone, which in turn reflects
the increasing hybridization of the HOMOu states of neighboring picene molecules
from Γ to Y. In contrast, the width of the lower HOMO (HOMOl) band along Γ–Y remains
almost unchanged, consistent with the fact that the HOMOl(Γ) and HOMOl(Y) states
exhibit the same degree of hybridization, so that the nodal structure of the wave
functions and the matrix elements of the self-energy correction are very similar.

text: The frequency-dependent dielectric function and the second-order polarizability
tensor of ferroelectric LiNbO3 are calculated from first principles. The calculations
are based on the electronic structure obtained from density-functional theory.
The subsequent application of the GW approximation to account for quasiparticle
effects and the solution of the Bethe–Salpeter equation yield a dielectric function
for the stoichiometric material that slightly overestimates the absorption onset
and the oscillator strength in comparison with experimental measurements. Calculations
at the level of the independent-particle approximation indicate that these deficiencies
are at least partially related to the neglect of intrinsic defects typical for
the congruent material. The second-order polarizability calculated within the
independent-particle approximation predicts strong nonlinear coefficients for
photon energies above 1.5 eV. The comparison with measured data suggests that
self-energy effects improve the agreement between experiment and theory. The intrinsic
defects of congruent samples reduce the optical nonlinearities, in particular
for the 21 and 31 tensor components, further improving the agreement with measured
data.

text: We investigate the band dispersion and relevant electronic properties of rubrene
single crystals within the GW approximation. Due to the self-energy correction,
the dispersion of the highest occupied molecular orbital (HOMO) band increases
by 0.10 eV compared to the dispersion of the Kohn-Sham eigenvalues within the
generalized gradient approximation, and the effective hole mass consequently decreases.
The resulting value of 0.90 times the electron rest mass along the Γ-Y direction
in the Brillouin zone is closer to experimental measurements than that obtained
from density-functional theory. The enhanced bandwidth is explained in terms of
the intermolecular hybridization of the HOMO(Y) wave function along the stacking
direction of the molecules. Overall, our results support the bandlike interpretation
of charge-carrier transport in rubrene.

text: The GW approximation for the electronic self-energy is an important tool for
the quantitative prediction of excited states in solids, but its mathematical
exploration is hampered by the fact that it must, in general, be evaluated numerically
even for very simple systems. In this paper I describe a nontrivial model consisting
of two electrons on the surface of a sphere, interacting with the normal long-range
Coulomb potential, and show that the GW self-energy, in the absence of self-consistency,
can in fact be derived completely analytically in this case. The resulting expression
is subsequently used to analyze the convergence of the energy gap between the
highest occupied and the lowest unoccupied quasiparticle orbital with respect
to the total number of states included in the spectral summations. The asymptotic
formula for the truncation error obtained in this way, whose dominant contribution
is proportional to the cutoff energy to the power −3/2, may be adapted to extrapolate
