  text: <jats:p>To model intermolecular excitation transfer between organic chromophores
    in the framework of Förster theory, the interaction matrix element is needed for
    all relative orientations and separations of chromophores. Simulations of extended
    multi-chromophoric systems thus require a fast but reliable approximation scheme
    to calculate these dipole interactions. By means of a comparative study of the
    dipole approximation with quantum chemistry, we demonstrate that the usual line-dipole
    theory, while suitable for short molecules, breaks down for longer molecules with
    inter-molecular separations similar to or smaller than the length of the interacting
    chromophores; a limit that is typically found in conjugated polymer thin films.
    As a remedy, we propose an improved way of distributing the sub-dipole moments
    within a line which provides results in very good agreement with the quantum chemistry,
    and is still simple enough to be used in large scale simulations.</jats:p>

  text: 'We present recent advances in numerical implementations of hybrid functionals
    and the GW approximation within the full-potential linearized augmented-plane-wave
    (FLAPW) method. The former is an approximation for the exchange–correlation contribution
    to the total energy functional in density-functional theory, and the latter is
    an approximation for the electronic self-energy in the framework of many-body
    perturbation theory. All implementations employ the mixed product basis, which
    has evolved into a versatile basis for the products of wave functions, describing
    the incoming and outgoing states of an electron that is scattered by interacting
    with another electron. It can thus be used for representing the nonlocal potential
    in hybrid functionals as well as the screened interaction and related quantities
    in GW calculations. In particular, the six-dimensional space integrals of the
    Hamiltonian exchange matrix elements (and exchange self-energy) decompose into
    sums over vector–matrix–vector products, which can be evaluated easily. The correlation
    part of the GW self-energy, which contains a time or frequency dependence, is
    calculated on the imaginary frequency axis with a subsequent analytic continuation
    to the real axis or, alternatively, by a direct frequency convolution of the Green
    function G and the dynamically screened Coulomb interaction W along a contour
    integration path that avoids the poles of the Green function. Hybrid-functional
    and GW calculations are notoriously computationally expensive. We present a number
    of tricks that reduce the computational cost considerably, including the use of
    spatial and time-reversal symmetries, modifications of the mixed product basis
    with the aim to optimize it for the correlation self-energy and another modification
    that makes the Coulomb matrix sparse, analytic expansions of the interaction potentials
    around the point of divergence at k=0, and a nested density and density-matrix
    convergence scheme for hybrid-functional calculations. We show CPU timings for
    prototype semiconductors and illustrative results for GdN and ZnO. '

  text: We report on the molecular beam epitaxy growth of cubic GaN on 3C–SiC (001)
    nanostructures. Transmission electron microscopy (TEM) studies show phase-pure
    cubic GaN crystals with a low defect density on top of the post shaped 3C–SiC
    nanostructures and GaN grown on their sidewalls, which is dominated by {111} planar
    defects. The nanostructures, aligned parallel and perpendicular to the [110] directions
    of the substrate, are located in anti-phase domains of the 3C–SiC/Si (001) substrate.
    These anti-phase domains strongly influence the optimum growth of GaN layers in
    these regions. TEM measurements demonstrate a different stacking fault density
    in the cubic GaN epilayer in these areas.

  text: We study the quantum properties and statistics of photons emitted by a quantum-dot
    biexciton inside a cavity. In the biexciton-exciton cascade, fine-structure splitting
    between exciton levels degrades polarization-entanglement for the emitted pair
    of photons. However, here we show that the polarization-entanglement can be preserved
    in such a system through simultaneous emission of two degenerate photons into
    cavity modes tuned to half the biexciton energy. Based on detailed theoretical
    calculations for realistic quantum-dot and cavity parameters, we quantify the
    degree of achievable entanglement.

  text: We design the geometrical shape of plasmonic nanostructures to achieve field
    patterns with desired properties. For this, we combine Maxwell simulations and
    automatic optimization techniques. By allowing variations of the geometrical shape,
    which can be based on either boxes or arbitrary polygons, we maximize the desired
    objective.

  text: "Results of atomistic simulations aimed at understanding precipitation of
    the highly attractive wide band gap\r\nsemiconductor material silicon carbide
    in silicon are presented. The study involves a systematic investigation of\r\nintrinsic
    and carbon-related defects as well as defect combinations and defect migration
    by both, quantummechanical\r\nfirst-principles as well as empirical potential
    methods. Comparing formation and activation energies,\r\nground-state structures
    of defects and defect combinations as well as energetically favorable agglomeration
    of\r\ndefects are predicted. Moreover, accurate ab initio calculations unveil
    limitations of the analytical method based\r\non a Tersoff-like bond order potential.
    A work-around is proposed in order to subsequently apply the highly efficient
    technique on large structures not accessible by first-principles methods. The
    outcome of both types of simulation provides a basic microscopic understanding
    of defect formation and structural evolution particularly at non-equilibrium conditions
    strongly deviated from the ground state as commonly found in SiC growth processes.
    A possible precipitation mechanism, which conforms well to experimental findings
    and clarifies contradictory views present in the literature is outlined."

  text: Using a finite-difference time-domain method, we theoretically investigate
    the optical spectra of crossing perpendicular photonic crystal waveguides with
    quantum dots embedded in the central rod. The waveguides are designed so that
    the light mainly propagates along one direction and the cross talk is greatly
    reduced in the transverse direction. It is shown that when a quantum dot (QD)
    is resonant with the cavity, strong coupling can be observed via both the transmission
    and crosstalk spectrum. If the cavity is far off-resonant from the QD, both the
    cavity mode and the QD signal can be detected in the transverse direction since
    the laser field is greatly suppressed in this direction. This structure could
    have strong implications for resonant excitation and in-plane detection of QD
    optical spectroscopy.

  text: We simulate the linear and nonlinear optical response from split-ring resonator
    (SRR) arrays to study collective effects between the constituent SRRs that determine
    spectral properties of the second harmonic generation (SHG). We apply the Discontinuous
    Galerkin Time Domain (DGTD) method and the hydrodynamic Maxwell-Vlasov model to
    calculate the SHG emission. Our model is able to qualitatively reproduce and explain
    the non-monotonic dependence of the spectral SHG transmission measured experimentally
    for SRR arrays with different lattice constants

  text: Optical experiments on second-harmonic generation from split-ring-resonator
    square arrays show a nonmonotonic dependence of the conversion efficiency on the
    lattice constant. This finding is interpreted in terms of a competition between
    dilution effects and linewidth or near-field changes due to interactions among
    the individual elements in the array.

  text: "A novel adaptive approach to compute the eigenenergies and eigenfunctions
    of the two-particle (electron-hole) Schrödinger equation including Coulomb attraction
    is presented. As an example, we analyze the energetically lowest exciton state
    of a thin one-dimensional semiconductor quantum wire in the presence of disorder
    which arises from the non-smooth interface between the wire and surrounding material.
    The eigenvalues of the corresponding Schrödinger equation, i.e., the one-dimensional
    exciton Wannier equation with disorder, correspond to the energies of excitons
    in the quantum wire. The wavefunctions, in turn, provide information on the optical
    properties of the wire.\r\n\r\nWe reformulate the problem of two interacting particles
    that both can move in one dimension as a stationary eigenvalue problem with two
    spacial dimensions in an appropriate weak form whose bilinear form is arranged
    to be symmetric, continuous, and coercive. The disorder of the wire is modelled
    by adding a potential in the Hamiltonian which is generated by normally distributed
    random numbers. The numerical solution of this problem is based on adaptive wavelets.
    Our scheme allows for a convergence proof of the resulting scheme together with
    complexity estimates. Numerical examples demonstrate the behavior of the smallest
    eigenvalue, the ground state energies of the exciton, together with the eigenstates
    depending on the strength and spatial correlation of disorder."
