  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: The influence of electronic many-body interactions, spin-orbit coupling, and
    thermal lattice vibrations on the electronic structure of lithium niobate is calculated
    from first principles. Self-energy calculations in the GW approximation show that
    the inclusion of self-consistency in the Green function G and the screened Coulomb
    potential W opens the band gap far stronger than found in previous G0W0 calculations
    but slightly overestimates its actual value due to the neglect of excitonic effects
    in W. A realistic frozen-lattice band gap of about 5.9 eV is obtained by combining
    hybrid density functional theory with the QSGW0 scheme. The renormalization of
    the band gap due to electron-phonon coupling, derived here using molecular dynamics
    as well as density functional perturbation theory, reduces this value by about
    0.5 eV at room temperature. Spin-orbit coupling does not noticeably modify the
    fundamental gap but gives rise to a Rashba-like spin texture in the conduction
    band.

  text: The phonon dispersions of the ferro‐ and paraelectric phase of LiTaO3 are
    calculated within density‐functional perturbation theory. The longitudinal optical
    phonon modes are theoretically derived and compared with available experimental
    data. Our results confirm the recent phonon assignment proposed by Margueron et
    al. [J. Appl. Phys. 111, 104105 (2012)] on the basis of spectroscopical studies.
    A comparison with the phonon band structure of the related material LiNbO3 shows
    minor differences that can be traced to the atomic‐mass difference between Ta
    and Nb. The presence of phonons with imaginary frequencies for the paraelectric
    phase suggests that it does not correspond to a minimum energy structure, and
    is compatible with an order‐disorder type phase transition.

  text: "Semiconductor quantum-dot cavity systems are promising sources for solid-state-based
    on-demand generation\r\nof single photons for quantum communication. Commonly,
    the spectral characteristics of the emitted single\r\nphoton are fixed by system
    properties such as electronic transition energies and spectral properties of the
    cavity.\r\nIn the present work we study cavity-enhanced single-photon generation
    from the quantum-dot biexciton through\r\na partly stimulated nondegenerate two-photon
    emission. We show that frequency and linewidth of the single\r\nphoton can be
    fully controlled by the stimulating laser pulse, ultimately allowing for efficient
    all-optical spectral\r\nshaping of the single photon."

  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: "Sources of single photons are key elements for applications in quantum information
    science.\r\nAmong the different sources available, semiconductor quantum dots
    excel with their\r\nintegrability in semiconductor on-chip solutions and the potential
    that photon emission can\r\nbe triggered on demand. Usually, the photon is emitted
    from a single-exciton ground state.\r\nPolarization of the photon and time of
    emission are either probabilistic or pre-determined by\r\nelectronic properties
    of the system. Here, we study the direct two-photon emission from the\r\nbiexciton.
    The two-photon emission is enabled by a laser pulse driving the system into a\r\nvirtual
    state inside the band gap. From this intermediate state, the single photon of
    interest\r\nis then spontaneously emitted. We show that emission through this
    higher-order\r\ntransition provides a versatile approach to generate a single
    photon. Through the driving\r\nlaser pulse, polarization state, frequency and
    emission time of the photon can be controlled\r\non-the-fly."
