  • 0.75 atoms improve the clock signal of 10,000 atoms 
    Kruse, I.; Lange, K.; Peise, J.; Lücke, Bernd; Pezzè, L.; Arlt, Jan J.; Ertmer, Wolfgang; Lisdat, C.; Santos, Luis; Smerzi, A.; Klempt, Carsten (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferometer, an ensemble of atoms is prepared in ...
  • A-posteriori error estimates for linear exterior problems via mixed-FEM and DTN mappings 
    Barrientos, Mauricio A.; Gatica, Gabriel N.; Maischak, Matthias (Cambridge : Cambridge University Press, 2002)
    In this paper we combine the dual-mixed finite element method with a Dirichlet-to-Neumann mapping (given in terms of a boundary integral operator) to solve linear exterior transmission problems in the plane. As a model we ...
  • Abelian torsion groups with a pseudocompact group topology 
    Comfort, W.W.; Remus, Dieter (Berlin : De Gruyter, 1994)
    Two questions are posed: (a) Which Abelian torsion groups admit a PGT (pseudocompact group topology)? (b) If an Abelian torsion group G admits a PGT, for which cardinal numbers a may such a topology F be chosen so that the ...
  • Accurate propagation of ultrashort pulses in nonlinear waveguides using propagation models for the analytic signal 
    Melchert, O.; Morgner, Uwe; Roth, B.; Babushkin, I.; Demircan, A. (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    We present a numerical approach for the accurate simulation of the complex propagation dynamics of ultrashort optical pulses in nonlinear waveguides, especially valid for few-cycle pulses. The propagation models are derived ...
  • Amplification of ultrafast pulses in an extended Mamyshev regenerator 
    Repgen, Paul; Wandt, Dieter; Morgner, Uwe; Neumann, Jörg; Kracht, Dietmar (Bellingham : SPIE, 2020)
    We present the characteristics of a high-energy ultrafast Yb-fiber laser system, based on a Mamyshev oscillator and a subsequently arranged fiber amplifier stage. The Mamyshev oscillator emits pulses at a repetition rate ...
  • Analysis of a two-phase model describing the growth of solid tumors 
    Escher, Joachim; Matioc, Anca-Voichita (Cambridge : Cambridge University Press, 2013)
    In this paper we consider a two-phase model describing the growth of avascular solid tumors when taking into account the effects of cell-to-cell adhesion and taxis due to nutrient. The tumor is surrounded by healthy tissue ...
  • Analytic solutions for a Stefan problem with Gibbs-Thomson correction 
    Escher, Joachim; Pruss, Jan; Simonett, Gieri (Berlin : Walter de Gruyter, 2003)
    We provide existence of a unique smooth solution for a class of one- and two-phase Stefan problems with Gibbs-Thomson correction in arbitrary space dimensions. In addition, it is shown that the moving interface depends ...
  • Approaches toward optimized laser-induced damage thresholds of dispersive compensating mirrors applying nanolaminates 
    Willemsen, T.; Brinkmann, M.; Jupé, M.; Gyamfi, M.; Schlichting, S.; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Ultra-short laser applications require high quality dielectric optics. The natural dispersion of light needs to be matched by dielectric components. However such dispersive components are very challenging for the deposition ...
  • An asymptotic formula for a-th powers dividing binomial coefficients 
    Sander, J.W. (Cambridge : Cambridge University Press, 1992)
    [No abstract available]
  • Asymptotic integration of second-order nonlinear difference equations 
    Ehrnström, Mats; Tisdell, Christopher C.; Wahlén, Erik (Cambridge : Cambridge University Press, 2011)
    In this work we analyse a nonlinear, second-order difference equation on an unbounded interval. We present new conditions under which the problem admits a unique solution that is of a particular linear asymptotic form. The ...
  • Eine Bemerkung über die Hurwitzschen Zahlen 
    Rieger, G.J. (Berlin : De Gruyter, 1977)
    [No abstract available]
  • Biodegradable microsphere-mediated cell perforation in microfluidic channel using femtosecond laser 
    Ishii, Atsuhiro; Ariyasu, Kazumasa; Mitsuhashi, Tatsuki; Heinemann, Dag; Heisterkamp, Alexander; Terakawa, Mitsuhiro (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    The use of small particles has expanded the capability of ultrashort pulsed laser optoinjection technology toward simultaneous treatment of multiple cells. The microfluidic platform is one of the attractive systems that ...
  • Brill-Noether loci in codimension two 
    Tarasca, N. (Cambridge : Cambridge University Press, 2013)
    Let us consider the locus in the moduli space of curves of genus 2k defined by curves with a pencil of degree k. Since the Brill-Noether number is equal to - 2, such a locus has codimension two. Using the method of test ...
  • Calibration accuracy of laser calorimetry for common crystal geometries 
    Willer, Yannick; Hao, Liu; Balasa, Istvan; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    An established method for precise determination of optical absorption is the so called laser calorimetry. According to ISO 115511 laser calorimetry is preferred to other photothermal test methods, because of its capability ...
  • Cluster tilting vs. weak cluster tilting in Dynkin type : A infinity 
    Holm, Thorsten; Jørgensen, Peter (Berlin : De Gruyter, 2015)
    This paper shows a new phenomenon in higher cluster tilting theory. For each positive integer d, we exhibit a triangulated category C with the following properties. On the one hand, the d-cluster tilting subcategories of ...
  • The co-stability manifold of a triangulated category 
    Jørgensen, Peter; Pauksztello, David (Cambridge : Cambridge University Press, 2013)
    Abstract Stability conditions on triangulated categories were introduced by Bridgeland as a 'continuous' generalisation of t-structures. The set of locally-finite stability conditions on a triangulated category is a manifold ...
  • Compact generation in partially ordered sets 
    Erné, Marcel (Cambridge : Cambridge University Press, 1987)
    Several` “classical” results on algebraic complete lattices extend to algebraic posets and, more generally, to so called compactly generated posets; but, of course, there may arise difficulties in the absence of certain ...
  • Computation of compound distributions i: Aliasing errors and exponential tilting 
    Grübel, Rudolf; Hermesmeier, Renate (Cambridge : Cambridge University Press, 1999)
    Numerical evaluation of compound distributions is one of the central numerical tasks in insurance mathematics. Two widely used techniques are Panjer recursion and transform methods. Many authors have pointed out that ...
  • Concept for high speed vocal cord imaging with swept-source optical coherence tomography 
    Zabic, Miroslav; Sharifpourboushehri, Sara; Müller-Wirts, Lennart; Benecke, Hannes; Heisterkamp, Alexander; Meyer, Heiko; Ripken, Tammo (Bellingham : SPIE, 2019)
    Optical coherence tomography (OCT) enables non-invasive depth-resolved investigation of laryngeal tissue. However, with conventional systems, OCT cross-sectional images of vibrating vocal cords always suffer from motion ...

    Rüsseler, Anna Karoline; Balasa, Istvan; Jensen, Lars; Ristau, Detlev (Bellingham : SPIE, 2018)
    Particles, which contaminate the substrate during thin film deposition, are prone to cause irremovable defects and demand special attention in the field of high precision laser optics as they can lead to localized absorption ...
