    The cavity-optomechanical radiation pressure interaction provides the means to create entanglement between a mechanical oscillator and an electromagnetic field interacting with it. Here we show how we can utilize this ...
  • Brell, Courtney G. (College Park, MD : American Physical Society, 2015)
    We propose a generalization of the color codes based on finite groups G. For non-Abelian groups, the resulting model supports non-Abelian anyonic quasiparticles and topological order. We examine the properties of these ...
  • Meyerholz, Marie M.; Mense, Kirsten; Lietzau, Michael; Kassens, Ana; Linden, Matthias; Knaack, Hendrike; Wirthgen, Elisa; Hoeflich, Andreas; Richard, Christophe; Sandra, Olivier; Schuberth, Hans-Joachim; Hoedemaker, Martina; Schmicke, Mari; Raliou, Mariam (Seoul : Korean Society of Veterinary Science, 2015)
    This study was conducted to determine if the main components of the somatotropic axis change during the early phase of pregnancy in the maternal blood system and whether differences exist on day 18 after pregnancy recognition ...
  • Blumenröther, Elias; Melchert, Oliver; Kanngießer, Jonas; Wollweber, Merve; Roth, Bernhard (Basel : MDPI, 2019)
    In this article, we present a simple and intuitive approach to create a handheld optoacoustic setup for near field measurements. A single piezoelectric transducer glued in between two sheets of polymethyl methacrylate ...
  • Pakhomov, A.V.; Arkhipov, R.M.; Arkhipov, M.V.; Demircan, A.; Morgner, U.; Rosanov, N.N.; Babushkin, Ihar (Berlin : Springer Nature, 2019)
    Up to now, full tunability of waveforms was possible only in electronics, up to radio-frequencies. Here we propose a new concept of producing few-cycle terahertz (THz) pulses with widely tunable waveforms. It is based on ...
  • Crisosto, Cristian (London : Hindawi, 2019)
    We present here a new method to predict cloud concentration five minutes in advance from all-sky images using the Artificial Neural Networks (ANN). An autoregressive neural network with backpropagation (Ar-BP) was created ...
  • Amri, Sirine; Corgier, Robin; Sugny, Dominique; Rasel, Ernst M.; Gaaloul, Naceur; Charron, Eric (Berlin : Springer Nature, 2019)
    Using Optimal Control Theory (OCT), we design fast ramps for the controlled transport of Bose-Einstein condensates with atom chips' magnetic traps. These ramps are engineered in the context of precision atom interferometry ...

    UV exposure, which is the main source for a sufficient level of vitamin D in the human body, is found to be up to a factor of 7 lower in Northern Germany (52° N) in the winter months compared to UV levels in thecentral ...
  • Cedzich, C.; Geib, T.; Stahl, C.; Velázquez, L.; Werner, A.H.; Werner, R.F. (Wien : Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2018)
    We provide a classification of translation invariant one-dimensional quantum walks with respect to continuous deformations preserving unitarity, locality, translation invariance, a gap condition, and some symmetry of the ...
  • Schwonnek, Rene (Wien : Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2018)
    We consider the uncertainty between two pairs of local projective measurements performed on a multipartite system. We show that the optimal bound in any linear uncertainty relation, formulated in terms of the Shannon ...
  • Crisosto, Cristian; Hofmann, Martin; Mubarak, Riyad; Seckmeyer, Gumther (Basel : MDPI, 2018)
    We present a method to predict the global horizontal irradiance (GHI) one hour ahead in one-minute resolution using Artificial Neural Networks (ANNs). A feed-forward neural network with Levenberg–Marquardt Backpropagation ...
  • Reiter, Florentin; Reeb, David; Sorensen, Anders S. (College Park : American Physical Society, 2016)
    We present a technique for the dissipative preparation of highly entangled multiparticle states of atoms coupled to common oscillator modes. By combining local spontaneous emission with coherent couplings, we engineer ...

    Do the laws of quantum physics still hold for macroscopic objects - this is at the heart of Schrodinger's cat paradox - or do gravitation or yet unknown effects set a limit for massive particles? What is the fundamental ...
  • Nakata, Yoshifumi; Hirche, Christoph; Morgan, Ciar; Winter, Andreas (Wien : Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2017)
    We investigate decoupling, one of the most important primitives in quantum Shannon theory, by replacing the uniformly distributed random unitaries commonly used to achieve the protocol, with repeated applications of random ...
  • Haegeman, Jutho; Draxler, Damian; Stojevic, Vid; Cirac, J. Ignacio; Osborne, Tobias J.; Verstraete, Frank (Amsterdam : SciPost Foundation, 2017)
    We introduce a non-commutative generalization of the Gross-Pitaevskii equation for one-dimensional quantum gasses and quantum liquids. This generalization is obtained by applying the time-dependent variational principle ...
  • Rode, Johannes C.; Smirnov, Dmitri; Schmidt, Hennrik; Haug, Rolf J. (Bristol : Institute of Physics Publishing IOP, 2016)
    The electronic dispersion of a graphene bilayer is highly dependent on rotational mismatch between layers and can be further manipulated by electrical gating. This allows for an unprecedented control over electronic ...
  • Weber, Stefan; Weske, Kerstin (Berlin : Springer, 2017)
    The paper presents a comprehensive model of a banking system that integrates network effects, bankruptcy costs, fire sales, and cross-holdings. For the integrated financial market we prove the existence of a price-payment ...

    The development of mathematical simulation and optimization models and algorithms for solving gas transport problems is an active field of research. In order to test and compare these models and algorithms, gas network ...

    In this paper we consider a special class of completely integrable systems that arise as transverse Hilbert schemes of d points of a complex symplectic surface S projecting onto ℂ via a surjective map p which is a submersion ...
