  text: "We study the complexity of problems solvable in deterministic polynomial
    time\r\nwith access to an NP or Quantum Merlin-Arthur (QMA)-oracle, such as $P^{NP}$\r\nand
    $P^{QMA}$, respectively. The former allows one to classify problems more\r\nfinely
    than the Polynomial-Time Hierarchy (PH), whereas the latter\r\ncharacterizes physically
    motivated problems such as Approximate Simulation\r\n(APX-SIM) [Ambainis, CCC
    2014]. In this area, a central role has been played by\r\nthe classes $P^{NP[\\log]}$
    and $P^{QMA[\\log]}$, defined identically to $P^{NP}$\r\nand $P^{QMA}$, except
    that only logarithmically many oracle queries are\r\nallowed. Here, [Gottlob,
    FOCS 1993] showed that if the adaptive queries made by\r\na $P^{NP}$ machine have
    a \"query graph\" which is a tree, then this computation\r\ncan be simulated in
    $P^{NP[\\log]}$.\r\n  In this work, we first show that for any verification class\r\n$C\\in\\{NP,MA,QCMA,QMA,QMA(2),NEXP,QMA_{\\exp}\\}$,
    any $P^C$ machine with a query\r\ngraph of \"separator number\" $s$ can be simulated
    using deterministic time\r\n$\\exp(s\\log n)$ and $s\\log n$ queries to a $C$-oracle.
    When $s\\in O(1)$ (which\r\nincludes the case of $O(1)$-treewidth, and thus also
    of trees), this gives an\r\nupper bound of $P^{C[\\log]}$, and when $s\\in O(\\log^k(n))$,
    this yields bound\r\n$QP^{C[\\log^{k+1}]}$ (QP meaning quasi-polynomial time).
    We next show how to\r\ncombine Gottlob's \"admissible-weighting function\" framework
    with the\r\n\"flag-qubit\" framework of [Watson, Bausch, Gharibian, 2020], obtaining
    a\r\nunified approach for embedding $P^C$ computations directly into APX-SIM\r\ninstances
    in a black-box fashion. Finally, we formalize a simple no-go\r\nstatement about
    polynomials (c.f. [Krentel, STOC 1986]): Given a multi-linear\r\npolynomial $p$
    specified via an arithmetic circuit, if one can \"weakly\r\ncompress\" $p$ so
    that its optimal value requires $m$ bits to represent, then\r\n$P^{NP}$ can be
    decided with only $m$ queries to an NP-oracle."

  text: With the rapid advances of functional dielectric metasurfaces and their integration
    on on-chip nanophotonic devices, the necessity of metasurfaces working in different
    environments, especially in biological applications, arose. However, the metasurfaces’
    performance is tied to the unit cell’s efficiency and ultimately the surrounding
    environment it was designed for, thus reducing its applicability if exposed to
    altering refractive index media. Here, we report a method to increase a metasurface’s
    versatility by covering the high-index metasurface with a low index porous SiO2
    film, protecting the metasurface from environmental changes while keeping the
    working efficiency unchanged. We show, that a covered metasurface retains its
    functionality even when exposed to fluidic environments.

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>The interaction
    between quantum light and matter is being intensively studied for systems that
    are enclosed in high-<jats:italic>Q</jats:italic> cavities which strongly enhance
    the light–matter coupling. Cavities with low <jats:italic>Q</jats:italic>-factors
    are generally given less attention due to their high losses that quickly destroy
    quantum systems. However, bad cavities can be utilized for several applications,
    where lower <jats:italic>Q</jats:italic>-factors are required, e.g., to increase
    the spectral width of the cavity mode. In this work, we demonstrate that low-<jats:italic>Q</jats:italic>
    cavities can be beneficial for preparing specific electronic steady states when
    certain quantum states of light are applied. We investigate the interaction between
    quantum light with various statistics and matter represented by a Λ-type three-level
    system in lossy cavities, assuming that cavity losses are the dominant loss mechanism.
    We show that cavity losses lead to non-trivial electronic steady states that can
    be controlled by the loss rate and the initial statistics of the quantum fields.
    We discuss the mechanism of the formation of such steady states on the basis of
    the equations of motion and present both analytical expressions and numerical
    simulations for such steady states.</jats:p>"

  text: <jats:title>Abstract</jats:title><jats:p>Tailored nanoscale quantum light
    sources, matching the specific needs of use cases, are crucial building blocks
    for photonic quantum technologies. Several different approaches to realize solid-state
    quantum emitters with high performance have been pursued and different concepts
    for energy tuning have been established. However, the properties of the emitted
    photons are always defined by the individual quantum emitter and can therefore
    not be controlled with full flexibility. Here we introduce an all-optical nonlinear
    method to tailor and control the single photon emission. We demonstrate a laser-controlled
    down-conversion process from an excited state of a semiconductor quantum three-level
    system. Based on this concept, we realize energy tuning and polarization control
    of the single photon emission with a control-laser field. Our results mark an
    important step towards tailored single photon emission from a photonic quantum
    system based on quantum optical principles.</jats:p>

  text: <jats:title>Abstract</jats:title><jats:p>Polarons influence decisively the
    performance of lithium niobate for optical applications. In this work, the formation
    of (defect) bound polarons in lithium niobate is studied by ab initio molecular
    dynamics. The calculations show a broad scatter of polaron formation times. Rising
    temperature increases the share of trajectories with long formation times, which
    leads to an overall increase of the average formation time with temperature. However,
    even at elevated temperatures, the average formation time does not exceed the
    value of 100 femtoseconds, i.e., a value close to the time measured for free,
    i.e., self-trapped polarons. Analyzing individual trajectories, it is found that
    the time required for the structural relaxation of the polarons depends sensitively
    on the excitation of the lithium niobate high-frequency phonon modes and their
    phase relation.</jats:p>

  text: We study the DC conductivity in potassium titanyl phosphate (KTiOPO4, KTP)
    and its isomorphs KTiOAsO4 (KTA) and Rb1%K99%TiOPO4 (RKTP) and introduce a method
    by which to reduce the overall ionic conductivity in KTP by a potassium nitrate
    treatment. Furthermore, we create so-called gray tracking in KTP and investigate
    the ionic conductivity in theses areas. A local unintended reduction of the ionic
    conductivity is observed in the gray-tracked regions, which also induce additional
    optical absorption in the material. We show that a thermal treatment in an oxygen-rich
    atmosphere removes the gray tracking and brings the ionic conductivity as well
    as the optical transmission back to the original level. These studies can help
    to choose the best material and treatment for specific applications.

  text: Online solvers for a series of standard 1-D or 2-D problems in integrated
    optics will be discussed. Implemented on the basis of HTML/JavaScript/SVG with
    core routines compiled from well tested C++-sources, the quasi-analytical algorithms
    require a computational load that can be handled easily even by current mobile
    devices. So far the series covers the 1-D guided modes of dielectric multilayer
    slab waveguides and the oblique plane wave reflection from these, the modes of
    rectangular channel waveguides (in an approximation of effective indices), bend
    modes of curved multilayer slabs, whispering-gallery resonances (“Quasi-Normal-Modes”)
    supported by circular dielectric cavities, the hybrid modes of circular multi-step-index
    optical fibers, bound and leaky modes of 1-D complex multilayers, including plasmonic
    surface modes, and, with restrictions, quite general rectangular scattering problems
    in 2-D.

  text: Many-body perturbation theory based on density-functional theory calculations
    is used to determine the quasiparticle band structures and the dielectric functions
    of the isomorphic ferroelectrics rubidium titanyl phosphate (RbTiOPO4) and potassium
    titanyl arsenide (KTiOAsO4). Self-energy corrections of more than 2 eV are found
    to widen the transport band gaps of both materials considerably to 5.3 and 5.2
    eV, respectively. At the same time, both materials are characterized by strong
    exciton binding energies of 1.4 and 1.5 eV, respectively. The solution of the
    Bethe-Salpeter equation based on the quasiparticle energies results in onsets
    of the optical absorption within the range of the measured data.
