  • Descent of tautological sheaves from Hilbert schemes to Enriques manifolds 
    Reede, Fabian (Berlin ; Heidelberg [u.a.] : Springer, 2024)
    Let X be a K3 surface which doubly covers an Enriques surface S. If n∈N is an odd number, then the Hilbert scheme of n-points X[n] admits a natural quotient S[n]. This quotient is an Enriques manifold in the sense of Oguiso ...
  • Laser noise residuals in LISA from on-board processing and time-delay interferometry 
    Staab, Martin; Lilley, Marc; Bayle, Jean-Baptiste; Hartwig, Olaf (Ridge, NY : American Physical Society, 2024)
    Time-delay interferometry (TDI) is a crucial step in the on-ground data processing pipeline of the Laser Interferometer Space Antenna (LISA), as it reduces otherwise overwhelming laser noise and allows for the detection ...
  • Common transversals and complements in abelian groups 
    Aivazidis, S.; Loukaki, M.; Sambale, B. (Dordrecht [u.a.] : Springer Science + Business Media B.V., 2024)
    Given a finite abelian group G and cyclic subgroups A, B, C of G of the same order, we find necessary and sufficient conditions for A, B, C to admit a common transversal for the cosets they afford. For an arbitrary number ...

    Metal-organic frameworks (MOFs) are highly versatile materials because of their tunable properties. However, the typically poor electrical conductivity of MOFs presents challenges for their integration into electrical ...
  • Broadband detection of 18 teeth in an 11-dB squeezing comb 
    Wilken, Dennis; Junker, Jonas; Heurs, Michèle (College Park, Md. [u.a.] : American Physical Society, 2024)
    Squeezed vacuum is a versatile resource of bipartite entanglement for quantum metrology and information. Optical parametric oscillators generate these states in a frequency comb structure. We show the simultaneous detection ...

    Fischer, Hendrik; Roth, Julian; Wick, Thomas; Chamoin, Ludovic; Fau, Amelie (Amsterdam : Elsevier, 2024)
    In this work, the dual-weighted residual (DWR) method is applied to obtain an error-controlled incremental proper orthogonal decomposition (POD) based reduced order model. A novel approach called MORe DWR (Model Order ...
  • A torsion balance as a weak-force testbed for novel optical inertial sensors 
    Bergmann, Gerald; Cordes, Carolin; Gentemann, Christoph; Händchen, Vitus; Qinglan, Wang; Yan, Hao; Danzmann, Karsten; Heinzel, Gerhard; Mehmet, Moritz (Bristol : IOP Publ., 2024)
    Torsion balances (TBs) are versatile instruments known for their ability to measure tiny forces and accelerations with high precision. We are currently commissioning a new TB facility to support the development and testing ...
  • Coherent photo-thermal noise cancellation in a dual-wavelength optical cavity for narrow-linewidth laser frequency stabilisation 
    Dawel, Fabian; Wilzewski, Alexander; Herbers, Sofia; Pelzer, Lennart; Kramer, Johannes; Hild, Marek B.; Dietze, Kai; Krinner, Ludwig; Spethmann, Nicolas C. H.; Schmidt, Piet O. (Washington, DC : Optica, 2024)
    Optical resonators are used for the realisation of ultra-stable frequency lasers. The use of high reflectivity multi-band coatings allows the frequency locking of several lasers of different wavelengths to a single cavity. ...
  • The Mullins–Sekerka problem via the method of potentials 
    Escher, Joachim; Matioc, Anca‐Voichita; Matioc, Bogdan‐Vasile (Weinheim : Wiley-VCH, 2024)
    It is shown that the two-dimensional Mullins–Sekerka problem is well-posed in all subcritical Sobolev spaces Hr (R) with r ϵ (3/2,2). This is the first result, where this issue is established in an unbounded geometry. The ...

    Dispersive Fourier transform is a characterization technique that allows directly extracting an optical spectrum from a time domain signal, thus providing access to real-time characterization of the signal spectrum. However, ...
  • Large-scale spatiotemporal calculation of photovoltaic capacity factors using ray tracing: A case study in urban environments 
    Bredemeier, Dennis; Schinke, Carsten; Niepelt, Raphael; Brendel, Rolf (Chichester : Wiley, 2023)
    Photovoltaics (PVs) on building facades, either building-integrated or building-attached, offer a large energy yield potential especially in densely populated urban areas. Targeting this potential requires the availability ...
  • Nicolai maps with four-fermion interactions 
    Casarin, Lorenzo; Lechtenfeld, Olaf; Rupprecht, Maximilian (Berlin ; Heidelberg : Springer, 2023)

    Kermarrec, Gaël; Maddanu, Federico; Klos, Anna; Proietti, Tommaso; Bogusz, Janusz (Berlin ; Heidelberg : Springer, 2024)
    Geodetic time series are usually modeled with a deterministic approach that includes trend, annual, and semiannual periodic components having constant amplitude and phase-lag. Although simple, this approach neglects the ...
