    FD-OCT systems with non-uniform wavenumber sampling require calibration and resampling routines to achieve optimal axial resolution. We present a simple calibration procedure and provide all necessary algorithmic ...
  • Müller, Vitali (Hannover : Gottfried Wilhelm Leibniz Universität, 2013-04-02)
    This thesis is separated into two parts. The first part is about satellite orbits for space-based gravitational wave detectors. Gravitational waves are ripples in the four-dimensional spacetime and were firstly predicted ...
  • Tzschoppe, Michael; Huck, Christian; Hötzel, Fabian; Günther, Benjamin; Mamiyev, Zamin; Butkevich, Andrey; Ulrich, Constantin; Gade, Lutz H.; Pucci, Annemarie (Bristol : IOP Publishing Ltd., 2019)
    The plasmonic signals of quasi-1D electron systems are a clear and direct measure of their metallic behavior. Due to the finite size of such systems in reality, plasmonic signals from a gold-induced superstructure on ...
  • Bargheer, Till; Coronado, Frank; Vieira, Pedro (Berlin; Heidelberg : Springer, 2019)
    We explain how the ’t Hooft expansion of correlators of half-BPS operators can be resummed in a large-charge limit in N = 4 super Yang-Mills theory. The full correlator in the limit is given by a non-trivial function of ...
  • Mubarak, Riyad; Schilke, Holger; Seckmeyer, Gunther (Basel : MDPI, 2021)
    Silicon-based sensors are widely used for monitoring solar irradiance, in particular, in the field of Photovoltaic (PV) applications. We present a method to correct the global horizontal irradiance measured by silicon-based ...
  • Thiem, Jonas; Ruehl, Axel; Ristau, Detlev (Basel : MDPI, 2021)
    In recent years, optical nanothermometers have seen huge improvements in terms of precision as well as versatility, and several research efforts have been directed at adapting novel active materials or further optimizing ...
  • Badorreck, Holger; Jensen, Lars; Ristau,Detlev; Jupé, Marco (Basel : MDPI, 2021)
    For the purpose of a deeper understanding of thin film growth, in the last two decades several groups developed models for simulation on the atomistic scale. Models using molecular dynamics as their simulation method already ...
  • Arkhipov, Rostislav; Pakhomov, Anton; Arkhipov, Mikhail; Babushkin, Ihar; Demircan, Ayhan; Morgner, Uwe; Rosanov, Nikolay (London : Nature Publishing Group, 2021)
    We study theoretically a possibility of creation and ultrafast control (erasing, spatial frequency multiplication) of population density gratings in a multi-level resonant medium having a resonance transition frequency in ...
  • Gross, Günter (Stuttgart : E. Schweizerbart Science Publishers, 2021)
    A viscous sublayer was introduced into a PBL model in order to specify the lower boundary condition for temperature. The simulated results have been compared against available observations. However, for such a comparison, ...
  • Melchert, Oliver; Demircan, Ayhan (Amsterdam [u.a.] : Elsevier, 2021)
    We present a Python toolkit for simulating the propagation dynamics of dissipative solitons in a variant of the Lugiato–Lefever equation (LLE) including dispersion terms of third and fourth order. In addition, the provided ...
  • Lachmann, Maike D.; Ahlers, Holger; Becker, Dennis; Dinkelaker, Aline N.; Grosse, Jens; Hellmig, Ortwin; Müntinga, Hauke; Schkolnik, Vladimir; Seidel, Stephan T.; Wendrich, Thijs; Wenzlawski, André; Carrick, Benjamin; Gaaloul, Naceur; Lüdtke, Daniel; Braxmaier, Claus; Ertmer, Wolfgang; Krutzik, Markus; Lämmerzahl, Claus; Peters, Achim; Schleich, Wolfgang P.; Sengstock, Klaus; Wicht, Andreas; Windpassinger, Patrick; Rasel, Ernst M. (London : Nature Publishing Group, 2021)
    Bose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne interferometry. Indeed, BECs enjoy a slowly expanding wave function, display a large spatial coherence and can be engineered and ...
  • Suar, Monali (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    There is a need to the development of hybrid simulation concepts to describe the light interactions with polymers. Usually, in order to develop comprehensive a description, a multi physics approach is required, i.e., to ...
  • Hamann, Ines; Sanjuan, Josep; Spannagel, Ruven; Gohlke, Martin; Wanner, Gudrun; Schuster, Sönke; Guzman, Felipe; Braxmaier, Claus (London u.a. : Taylor and Francis, 2019)
    Marginal changes in geometrical dimensions due to temperature changes affect the performance of optical instruments. Highly dimensionally stable materials can minimize these effects since they offer low coefficients of ...
  • Cheptsov, V.S.; Tsypina, S.I.; Minaev, N.V.; Yusupov, V.I.; Chichkov, B.N. (Singapur : Whioce, 2019)
    The study of biodiversity, growth, development, and metabolism of cultivated microorganisms is an integral part of modern microbiological, biotechnological, and medical research. Such studies require the development of new ...
  • Brinkmann, Hannes; Patzschke, Michael; Kaden, Peter; Raiwa, Manuel; Rossberg, André; Kloditz, Roger; Heim, Karsten; Moll, Henry; Stumpf, Thorsten (London : Royal Society of Chemistry, 2019)
    Cellulosic materials present as tissue, paper, wood, or filter materials in low and intermediate level waste will degrade under alkaline conditions if water ingresses in a cementitious backfilled repository. The main ...
  • Paczkowski, Sarah (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    This thesis focusses on laser frequency stabilisation and interferometer path length differences on LISA Pathfinder (LPF). LPF was a satellite mission, in operation from December 2015 until July 2017, to demonstrate key ...
  • Lechtenfeld, Olaf; Zhilin, Gleb (Trieste : SISSA, 2019)
    We set up a correspondence between solutions of the Yang-Mills equations on R×S3 and in Minkowski spacetime via de Sitter space. Some known Abelian and non-Abelian exact solutions are rederived. For the Maxwell case we ...
