  text: "In light of growing demands for resource efficiency and sustainability in
    vehicle engineering, the environmentally compatible separation of structural adhesive
    joints is gaining increasing relevance. This study presents a comparative analysis
    of two physically based debonding methods: the established hot-air process and
    a cryogenic cold process based on liquid nitrogen (LN2). The primary objective
    is to assess the ecological impact and process-related sustainability of both
    approaches.\r\nExperimental investigations were conducted on a component-representative
    triple-sheet structure that simulates common automotive flange joints. Thermal
    input was applied either by convective heating using a hot air gun or by direct
    cooling through a contact-based LN2 tool. The resulting temperature profiles were
    recorded using spatially distributed thermocouples. Subsequently, the outer panel
    was selectively debonded to replicate a repair scenario, and the mechanical integrity
    of the remaining adhesive joint was evaluated through Mode I testing of L-shaped
    specimens. Process data served as input for an Life Cycle Assessment (LCA) according
    to DIN EN ISO 14040.\r\nThe cryogenic method achieved a 40% reduction in carbon
    footprint compared to the hot-air process (0.337 kg vs. 0.559 kg CO2-equivalents),
    primarily due to its shorter process time and more efficient heat transfer. While
    the hot-air method’s impact is mainly driven by electrical energy use, that of
    the cold method stems from cryogenic media consumption. Notwithstanding certain
    disadvantages in specific impact categories, the LN2-based process exhibits a
    superior overall ecological performance and signifies a promising solution for
    repair- and recycling-oriented adhesive separation in structural vehicle applications."

  text: We present the design and characterization of a guided-wave, bright, and highly
    frequency non-degenerate parametric down-conversion (PDC) source in thin-film
    lithium niobate. The source generates photon pairs with wavelengths of 815 nm
    and 1550 nm, linking the visible wavelength regime with telecommunication wavelengths.
    We confirm the high quality of the generated single photons by determining a value
    for the heralded second-order correlation function as low as g_h^(2)=(6.7+/-1.1)*10^8-3).
    Furthermore, we achieve a high spectral brightness of 0.44·10pairs/(smWGHz) which
    is two orders of magnitude higher than sources based on weakly guiding waveguides.
    The shape of the PDC spectrum and the strong agreement between the effective and
    nominal bandwidth highlight our high fabrication quality of periodically poled
    waveguides. The good agreement between the measured and simulated spectral characteristics
    of our source demonstrates our excellent understanding of the PDC process. Our
    result is a valuable step towards practical and scalable quantum communication
    networks as well as photonic quantum computing.

  text: Periodically poled thin-film lithium niobate (TFLN) crystals are the fundamental
    building block for highly-efficient quantum light sources and frequency converters.
    The efficiency of these devices is strongly dependent on the interaction length
    between the light and the nonlinear material, scaling quadratically with this
    parameter. Nevertheless, the fabrication of long, continuously poled areas in
    TFLN remains challenging, the length of continuously poled areas rarely exceeds
    10 mm. In this work, we demonstrate a significant progress in this field achieving
    the periodic poling of continuous poled areas of 70 mm length with a 3 μm poling
    period and a close to 50 % duty cycle. We compare two poling electrode design
    approaches to fabricate long, continuous poled areas. The first approach involves
    the poling of a single, continuous 70 mm long electrode. The second utilize a
    segmented approach including the poling of more than 20 individual sections forming
    together a 70 mm long poling area with no stitching errors. While the continuous
    electrode allows for faster fabrication, the segmented approach allows to individually
    optimize the poling resulting in less duty cycle variation. A detailed analysis
    of the periodic poling results reveals that the results of both are consistent
    with previously reported poling outcomes for shorter devices. Thus, we demonstrate
    wafer-scale periodic poling exceeding chiplet-size without any loss in the periodic
    poling quality. Our work presents a key step towards highly-efficient, narrow-bandwidth
    and low-pump power nonlinear optical devices.

  text: <jats:p>Boson sampling is a key candidate for demonstrating quantum advantage
    and has already yielded significant advances in quantum simulation, machine learning,
    and graph theory. In this work, a unification and extension of distinct forms
    of boson sampling is developed. The devised protocol merges discrete-variable
    scattershot boson sampling with continuous-variable Gaussian boson sampling. Therefore,
    it is rendered possible to harness the complexity of more interesting states,
    such as squeezed photons, in advanced sampling protocols. A generating function
    formalism is developed for the joint description of multiphoton and multimode
    light undergoing Gaussian transformations. The resulting analytical tools enable
    one to explore interfaces of different photonic quantum-information-processing
    platforms. A numerical simulation of unified sampling is carried out, benchmarking
    its performance, complexity, and scalability. Entanglement is characterized to
    exemplify the generation of quantum correlations from the nonlinear interactions
    of a unified sampler.</jats:p>

  text: 'We introduce a new classification of multimode states with a fixed number
    of photons. This classification is based on the factorizability of homogeneous
    multivariate polynomials and is invariant under unitary transformations. The classes
    physically correspond to field excitations in terms of single and multiple photons,
    each of which being in an arbitrary irreducible superposition of quantized modes.
    We further show how the transitions between classes are rendered possible by photon
    addition, photon subtraction, and photon-projection nonlinearities. We explicitly
    put forward a design for a multilayer interferometer in which the states for different
    classes can be generated with state-of-the-art experimental techniques. Limitations
    of the proposed designs are analyzed using the introduced classification, providing
    a benchmark for the robustness of certain states and classes. '

  text: <jats:p>Stable and bright single photon sources are key components for future
    quantum applications. A simple fabrication method is an important requirement
    for such sources. Here, we present a single photon source based on diced ridge
    waveguides in titanium indiffused LiNbO<jats:sub>3</jats:sub>. These waveguides
    can be easily fabricated by combining planar titanium in-diffusion without lithographic
    patterning and easy-to-handle precision dicing. Such devices have the potential
    to generate high single photon rates because ridge structures are typically less
    prone to the photorefractive effect. We achieve waveguide propagation losses &lt;0.4dBcm
    and a SHG conversion efficiency of about 81%Wcm<jats:sup>2</jats:sup>. Harnessing
    a type-0 SPDC process to generate 1550 nm photons, we obtain a SPDC brightness
    of 3⋅10<jats:sup>5</jats:sup>1s⋅mW⋅nm, with a heralding efficiency of <jats:italic>η</jats:italic><jats:sub>h</jats:sub>=45%
    (<jats:italic>η</jats:italic><jats:sub>h,wg</jats:sub>=77.5% for the waveguide
    itself excluded setup losses) and a heralded second-order correlation function
    of <jats:italic>g</jats:italic><jats:sub>h</jats:sub><jats:sup>2</jats:sup>(0)&lt;0.003
    at low pump powers.</jats:p>

  text: Stress plays a crucial role in thin films and layered systems, and thus significantly
    influences the material's electrical, mechanical and (nonlinear) optical responses.
    Despite lithium niobate's wide applicability as a nonlinear optical material,
    the impact of mechanical stress on its nonlinear optical properties is not well
    characterized. In this work, we systematically study both experimentally and theoretically,
    the nonlinear optical responses of thin film lithium niobate (TFLN) single crystals.
    Compressive and tensile stress is applied in our experiment using a piezodriven
    strain cell. We then record the second-harmonic-generated (SHG) response in back-reflection
    geometry, and compare these results to theoretical modeling using density functional
    theory (DFT). Both methods consistently reveal that uniaxial stress induces changes
    of the nonlinear optical susceptibility of certain tensor elements on the order
    of up to 1 pm/(V GPa). The exact value depends on the tensor element that is addressed
    in our SHG analysis, on the crystal orientation, and also whether using compressive
    or tensile stresses. Furthermore, a lowering of the crystal symmetry when applying
    stress along the <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"><a:mi>x</a:mi></a:math>
    or <b:math xmlns:b="http://www.w3.org/1998/Math/MathML"><b:mi>y</b:mi></b:math>
    crystallographic axes is observed by the appearance of new nonlinear optical tensor
    elements within the strained crystals.

  text: In this work, we introduce PHOENIX, a highly optimized explicit open-source
    solver for two-dimensional nonlinear Schrödinger equations with extensions. The
    nonlinear Schrödinger equation and its extensions (Gross-Pitaevskii equation)
    are widely studied to model and analyze complex phenomena in fields such as optics,
    condensed matter physics, fluid dynamics, and plasma physics. It serves as a powerful
    tool for understanding nonlinear wave dynamics, soliton formation, and the interplay
    between nonlinearity, dispersion, and diffraction. By extending the nonlinear
    Schrödinger equation, various physical effects such as non-Hermiticity, spin-orbit
    interaction, and quantum optical aspects can be incorporated. PHOENIX is designed
    to accommodate a wide range of applications by a straightforward extendability
    without the need for user knowledge of computing architectures or performance
    optimization. The high performance and power efficiency of PHOENIX are demonstrated
    on a wide range of entry-class to high-end consumer and high-performance computing
    GPUs and CPUs. Compared to a more conventional MATLAB implementation, a speedup
    of up to three orders of magnitude and energy savings of up to 99.8% are achieved.
    The performance is compared to a performance model showing that PHOENIX performs
    close to the relevant performance bounds in many situations. The possibilities
    of PHOENIX are demonstrated with a range of practical examples from the realm
    of nonlinear (quantum) photonics in planar microresonators with active media including
    exciton-polariton condensates. Examples range from solutions on very large grids,
    the use of local optimization algorithms, to Monte Carlo ensemble evolutions with
    quantum noise enabling the tomography of the system's quantum state.

  text: <jats:title>Abstract</jats:title><jats:p>AlInP (001) is widely utilized as
    a window layer in optoelectronic devices, including world‐record III‐V multi‐junction
    solar cells and photoelectrochemical (PEC) cells. The chemical and electronic
    properties of AlInP (001) depend on its surface reconstruction, which impacts
    its interaction with electrolytes in PEC applications and passivation layers.
    This study investigates AlInP (001) surface reconstructions using density functional
    theory and experimental methods. Phosphorus‐rich (P‐rich) and indium‐rich (In‐rich)
    AlInP surfaces are prepared with in situ monitoring of the process by reflection
    anisotropy (RA) spectroscopy and confirmed by low‐energy electron diffraction
    and photoemission spectroscopy. The experimental RA spectra closely match the
    theoretical predictions obtained by solving the Bethe–Salpeter equation. It is
    shown that missing hydrogen on P‐rich surfaces and formation of In–In 1D atomic
    chains on In‐rich surfaces introduce mid‐gap surface states that pin the Fermi
    level and induce band bending. Time‐resolved two‐photon photoemission measurements
    reveal ultrafast near‐surface electron dynamics for both P‐rich and In‐rich surfaces,
    demonstrating photoexcited electrons reaching the surface conduction band minimum
    and relaxing to mid‐gap surface states on about hundreds of fs. This work provides
    the most extensive AlInP surface analysis to date, allowing for more targeted
    surface and interface engineering, which is crucial for the optimization and design
    of III‐V heterostructures.</jats:p>
