  • Alvarez, M.; Baldauf, T.; Bond, R.; Dalal, N.; de Putter, R.; Dorè, O.; Green, D.; Hirata, C.; Huang, Z.; Huterer, D.; Jeong, D.; Johnson, M.C.; Krause, E.; Loverde, M.; Meyers, J.; Meerburg, P.D.; Senatore, L.; Shandera, S.; Silverstein, E.; Slosar, A.; Smith, K.; Zaldarriaga, M.; Assassi, V.; Braden, J.; Hajian, A.; Kobayashi, T.; Stein, G.; van Engelen, A. (2014-12-15)
    The statistics of primordial curvature fluctuations are our window into the period of inflation, where these fluctuations were generated. To date, the cosmic microwave background has been the domi nant source of information ...
  • Schwetz, Thomas; Winter, Walter (2005)
    We propose that reactor experiments could be used to constrain the environment dependence of neutrino mass and mixing parameters, which could be induced due to an acceleron coupling to matter fields. There are several ...
  • Petcov, Serguey T. (2005)
    The compelling experimental evidences for oscillations of solar and atmospheric neutrinos imply the existence of 3-neutrino mixing in vacuum. We briefly review the phenomenology of 3-v mixing, and the current data on the ...
  • Davoli, Elisa (SISSA, 2011-06-30)
    The subject of this paper is the rigorous derivation of lower dimensional models for a nonlinearly elastic thin-walled beam whose cross-section is given by a thin tubular neighbourhood of a smooth curve. Denoting by h and ...
  • Colombini, Ferruccio; Del Santo, Daniele; Fanelli, Francesco; Metivier, Guy (2013-02-04)
    In this paper we will study the Cauchy problem for strictly hyperbolic operators with low regularity coe fficients in any space dimension N ≥ 1. We will suppose the coe fficients to be log-Zygmund continuous in time and ...
  • Boscain, Ugo; Mason, Paolo (2005)
    In this paper we consider the minimum time population transfer problem for the z-component of the spin of a (spin 1/2) particle driven by a magnetic field, controlled along the x axis, with bounded amplitude. On the Bloch ...
  • Boscain, Ugo; Mason, Paolo (2005-06-20)
    On a two-level quantum system driven by an external field, we consider the population transfer problem from the first to the second level, minimizing the time of transfer, with bounded field amplitude. On the Bloch sphere ...
  • Baldi, Pietro; Berti, Massimiliano; Haus, Emanuele; Montalto, Riccardo (2017)
    We prove the existence and the linear stability of Cantor families of small amplitude time quasi-periodic standing water wave solutions - namely periodic and even in the space variable x - of a bi-dimensional ocean with ...
  • Dal Maso, Gianni; DeSimone, Antonio; Mora, Maria Giovanna; Morini, Massimiliano (2005)
    In this paper some new tools for the study of evolution problems in the framework of Young measures are introduced. A suitable notion of time-dependent system of generalized Young measures is defined, which allows to extend ...
  • Maccaferri, Carlo; Scherer Santos, Ricardo Jose; Tolla, Driba Demissie (2005-06-20)
    We extend the analysis of hep-th/0409063 to the case of a constant electric field turned on the worldvolume and on a transverse direction of a D-brane. We show that time localization is still obtained by inverting the ...
  • DeSimone, Antonio; Heltai, Luca; Manigrasso, Cataldo (2009-07-30)
    The deal.II finite element library was originally designed to solve partial differential equations defined on one, two or three space dimensions, mostly via the Finite Element Method. In its versions prior to version 6.2, ...
  • Bonora, Loriano; Maccaferri, Carlo; Mamone, Davide; Salizzoni, Mario (SISSA, 2003)
    This review of bosonic string field theory is concentrated on two main subjects. In the first part we revisit the construction of the three string vertex and rederive the relevant Neumann coefficients both for the matter ...
  • Evslin, Jarah; Minasian, Ruben (2008-04-14)
    We add to the mounting evidence that the topological B model's normalized holomorphic three-form has integral periods by demonstrating that otherwise the B2-brane partition function is ill-defined. The resulting Calabi-Yau ...
  • Baulieu, Laurent; Bossard, Guillaume; Tanzini, Alessandro (2005)
    The scalar and vector topological Yang-Mills symmetries determine a closed and consistent sector of Yang-Mills supersymmetry. We provide a geometrical construction of these symmetries, based on a horizontality condition ...
  • Bonora, Loriano; Bouatta, N.; Maccaferri, Carlo (2006-10-04)
    We establish a translation dictionary between open and closed strings, starting from open string field theory. Under this correspondence, (off-shell) level-matched closed string states are represented by star algebra ...
  • Grosche, Christian (SISSA, 1993-08-17)
    In this contribution I present further results on steps towards a Table of Feynman Path Integrals. Whereas the usual path integral solutions of the harmonic oscillator (Gaussian path integrals), of the radial harmonic ...
  • Khotyakov, Mikhail; Michelangeli, Alessandro (SISSA, 2015)
    This is an accurate translation from Russian and adaptation to the modern mathematical jargon of a classical paper by M. Sh. Birman published in 1956, which is still today central in the theory of self-adjoint extensions ...
  • Dal Maso, Gianni; Franzina, Giovanni; Zucco, Davide (2018-03)
    We study the asymptotic behaviour of solutions to variational problems in perforated domains with Neumann boundary conditions. We consider perforations that in the limit concentrate on a smooth manifold. We characterise ...
  • Caruso, Noe; Michelangeli, Alessandro; Novati, Paolo (SISSA, 2018)
    We present a general discussion of the main features and issues that (bounded) inverse linear problems in Hilbert space exhibit when the dimension of the space is infinite. This includes the set-up of a consistent ...
  • Piacitelli, Gherardo (2009-01-22)
    In this letter we wish to clarify in which sense the tensor nature of the commutation relations [x^mu,x^nu]=i theta ^{mu nu} underlying Minkowski spacetime quantisation cannot be suppressed even in the twisted approach to ...
