  text: We present the synthesis of indium oxide (In2O3) inverse opal films with photonic
    stop bands in the visible range by a structure replication method. Artificial
    opal films made of poly(methyl methacrylate) (PMMA) spheres are utilized as template.
    The opal films are deposited via sedimentation facilitated by ultrasonication,
    and then impregnated by indium nitrate solution, which is thermally converted
    to In2O3 after drying. The quality of the resulting inverse opal film depends
    on many parameters; in this study the water content of the indium nitrate/PMMA
    composite after drying is investigated. Comparison of the reflectance spectra
    recorded by vis-spectroscopy with simulated data shows a good agreement between
    the peak position and calculated stop band positions for the inverse opals. This
    synthesis is less complex and highly efficient compared to most other techniques
    and is suitable for use in many applications.

  text: "The dynamics of a pair of harmonic oscillators represented by three-dimensional
    fields coupled with a repulsive cubic nonlinearity is investigated through direct
    simulations of the respective field equations and with the help of the finite-mode
    Galerkin approximation (GA), which represents the two interacting fields by a
    superposition of \r\n3+3 harmonic-oscillator p-wave eigenfunctions with orbital
    and magnetic quantum numbers l=1 and m=1, 0, −1. The system can be implemented
    in binary Bose-Einstein condensates, demonstrating the potential of the atomic
    condensates to emulate various complex modes predicted by classical field theories.
    First, the GA very accurately predicts a broadly degenerate set of the system's
    ground states in the p-wave manifold, in the form of complexes built of a dipole
    coaxial with another dipole or vortex, as well as complexes built of mutually
    orthogonal dipoles. Next, pairs of noncoaxial vortices and/or dipoles, including
    pairs of mutually perpendicular vortices, develop remarkably stable dynamical
    regimes, which feature periodic exchange of the angular momentum and periodic
    switching between dipoles and vortices. For a moderately strong nonlinearity,
    simulations of the coupled-field equations agree very well with results produced
    by the GA, demonstrating that the dynamics is accurately spanned by the set of
    six modes limited to l=1."

  text: "A microscopic approach that is based on the multisubband semiconductor Bloch
    equations formulated in the basis of a 14-band k⋅p model is employed to compute
    the temporal dynamics of photocurrents in GaAs quantum wells following excitation
    with femtosecond laser pulses. This approach provides a transparent description
    of the interband, intersubband, and intraband excitations, fully includes all
    resonant as well as off-resonant excitations, and treats the light-matter interaction
    nonperturbatively. For linearly polarized excitations, the photocurrents contain
    contributions from shift and rectification currents. We numerically compute and
    analyze these currents generated by excitation with femtosecond laser pulses for
    [110]- and [111]-oriented GaAs quantum wells. It is shown that the often employed
    perturbative \r\nχ(2) approach breaks down for peak fields larger than about 10
    kV/cm, and that nonperturbative effects lead to a reduction of the peak values
    of the shift and rectification currents and to temporal oscillations that originate
    from Rabi flopping. In particular, we find a complex oscillatory photon energy
    dependence of the magnitudes of the shift and rectification currents. Our simulations
    demonstrate that this dependence is the result of mixing between the heavy- and
    light-hole valence bands. This is a surprising finding since the band mixing has
    an even larger influence on the strength of the photocurrents than the absorption
    coefficient. For [110]-oriented GaAs quantum wells, the calculated photon energy
    dependence is compared to experimental results, and good agreement is obtained.
    This validates our theoretical approach."

  text: Nonlinearity is the driving force for numerous important effects in nature
    typically showing transitions between different regimes, regular, chaotic or catastrophic
    behavior. Localized nonlinear modes have been the focus of intense research in
    areas such as fluid and gas dynamics, photonics, atomic and solid state physics
    etc. Due to the richness of the behavior of nonlinear systems and due to the severe
    numerical demands of accurate three-dimensional (3D) numerical simulations presently
    only little knowledge is available on the dynamics of complex nonlinear modes
    in 3D. Here, we investigate the dynamics of 3D non-coaxial matter wave vortices
    that are trapped in a parabolic potential and interact via a repulsive nonlinearity.
    Our numerical simulations demonstrate the existence of an unexpected and fascinating
    nonlinear regime that starts immediately when the nonlinearity is switched-on
    and is characterized by a smooth dynamics representing torque-free precession
    with nutations. The reported motion is proven to be robust regarding various effects
    such as the number of particles, dissipation and trap deformations and thus should
    be observable in suitably designed experiments. Since our theoretical approach,
    i.e., coupled nonlinear Schrödinger equations, is quite generic, we expect that
    the obtained novel dynamical behavior should also exist in other nonlinear systems.

  text: We investigate the transient optical response in high-quality Cd0.88Zn0.12Te
    crystals in the regime of slow light propagation on the lower exciton-polariton
    branch. Femtosecond photoexcitation leads to very substantial transmission changes
    in a ∼10-meV broad spectral range within the transparency window of the unexcited
    semiconductor. These nonlinear optical signatures decay on picosecond time scales
    governed by carrier thermalization and recombination. The temporal and spectral
    dependence indicate the dynamical optical response as arising from excitation-induced
    dephasing and perturbed free induction decay. Model simulations for the optical
    response taking into account the actual exciton-polariton dispersion and excitation-induced
    dephasing of a nonlinearly driven two-level system support this interpretation.

  text: Spins in semiconductor quantum dots have been considered as prospective quantum
    bit excitations. Their coupling to the crystal environment manifests itself in
    a limitation of the spin coherence times to the microsecond range, both for electron
    and hole spins. This rather short-lived coherence compared to atomic states asks
    for manipulations on timescales as short as possible. Due to the huge dipole moment
    for transitions between the valence and conduction band, pulsed laser systems
    offer the possibility to perform manipulations within picoseconds or even faster.
    Here, we report on results that show the potential of optical spin manipulations
    with currently available pulsed laser systems. Using picosecond laser pulses,
    we demonstrate optically induced spin rotations of electron and hole spins. We
    further realize the optical decoupling of the hole spins from the nuclear surrounding
    at the nanosecond timescales and demonstrate an all-optical spin tomography for
    interacting electron spin sub-ensembles.

  text: For incident light polarized perpendicular to the tube axis the multi-band
    semiconductor Bloch equations (MB-SBEs) that involve various screened interband
    Coulomb interactions (ICIs) are derived. The calculated E 12 peak is very close
    to the longitudinal excitonic peak E 22. Compared with the previous theoretical
    peak positions, the blue-shift of the peak in our results is about 0.5 eV. Then,
    subsequent detailed analyses show that the screening effect on the diagonal ICIs
    (D-ICIs) plays a key role in this big blue-shift. The valley-degenerate transverse
    pair excitations holding the same selection rule further enhance the screening
    effect on D-ICIs. Specially at q = 0 the dielectric function acting on the D-ICIs
    enhances two times. In our calculation the strong screening effect contributes
    90% of the big blue-shift, while the non-diagonal ICIs (ND-ICIs) contribute to
    10% of the blue-shift.

  text: A method is presented to transfer a system of two-level atoms from a spin
    coherent state to a maximally spin squeezed Dicke state, relevant for quantum
    metrology and quantum information processing. The initial state is the ground
    state of an initial linear Hamiltonian that is gradually turned into a final quadratic
    Hamiltonian whose ground state is the selected Dicke state. We use compensating
    operators to suppress diabatic transitions to unwanted states that would occur
    if the change were not slow. We discuss the possibilities of constructing the
    compensating operators by sequential application of quadratic Hamiltonians available
    in experiments.

  text: We propose an entanglement classification for symmetric quantum states based
    on their diagonal matrix-product-state (MPS) representation. The proposed classification,
    which preserves the stochastic local operation assisted with classical communication
    (SLOCC) criterion, relates entanglement families to the interaction length of
    Hamiltonians. In this manner, we establish a connection between entanglement classification
    and condensed matter models from a quantum information perspective. Moreover,
    we introduce a scalable nesting property for the proposed entanglement classification,
    in which the families for N parties carry over to the N + 1 case. Finally, using
    techniques from algebraic geometry, we prove that the minimal nontrivial interaction
    length n for any symmetric state is bounded by .

  text: The discovery of Airy waves, in the context of solutions to the linear Schrödinger
    equation [1], inspired extensive research for self-accelerating waves in optical
    settings [2-6]. Fascinating self-accelerating, self-healing light beams propagating
    along the bending trajectories can manifest themself in the spatial and the temporal
    domains and are promising for a large variety of potential applications.

  text: Recently, a new class of nonlinear systems was introduced, in which the self-trapping
    of fundamental and vortical localized modes in space of dimension D is supported
    by cubic self-repulsion with a strength growing as a function of the distance
    from the center, r, at any rate faster that rD. These systems support robust 2D
    and 3D modes which either do not exist or are unstable in other nonlinear systems.
    Here we demonstrate a possibility to create solitary vortices in this setting
    by applying a phase-imprinting torque to the ground state. Initially, a strong
    torque completely destroys the ground state. However, contrary to usual systems,
    where the destruction is irreversible, the present ones demonstrate a rapid restabilization
    and the creation of one or several shifted vortices orbiting the center. For the
    sake of comparison, we show analytically that, in the linear system with a 3D
    trapping potential, the action of a torque on the ground state is inefficient
    and creates only even-vorticity states with a small probability.
