  • Bruzzo, Ugo; Diaconescu, Duiliu-Emanuel; Yardim, M.; Pan, G.; Zhang, Y.; Chuang Wu-yen (SISSA, 2011-01)
    A supersymmetric quantum mechanical model is constructed for BPS states bound to surface operators in five dimensional SU(r) gauge theories using D-brane engineering. This model represents the effective action of a certain ...
  • Regis, Marco; Serone, Marco; Ullio, Piero (2007-01-31)
    We show that a recently constructed five-dimensional (5D) model with gauge-Higgs unification and explicit Lorentz symmetry breaking in the bulk, provides a natural dark matter candidate. This is the lightest Kaluza-Klein ...
  • Provenza, Alessio; Quiros, Mariano; Ullio, Piero (2006-09-07)
    We consider the split extended (N=2) supersymmetry scenario recently proposed by Antoniadis et al. [hep-ph/0507192] as a realistic low energy framework arising from intersecting brane models. While all scalar superpartners ...
  • Bangerth, Wolfgang; Heister, Timo; Heltai, Luca; Kanschat, Guido; Kronbichler, Martin; Maier, Matthias; Turcksin, Bruno; Young, Toby D. (SISSA, 2013-12-08)
    This paper provides an overview of the new features of the finite element library deal.II version 8.0.
  • Delfino, Gesualdo; Grinza, Paolo; Mussardo, Giuseppe (2006-02-02)
    The two-dimensional scaling Ising model in a magnetic field at critical temperature is integrable and possesses eight stable particles Ai (i = 1, . . . , 8) with different masses. The heaviest five lie above threshold and ...
  • Bianchini, Stefano; Bardelloni, Mauro (SISSA, 2014)
  • Giomi, Luca; Bowick, Mark J.; Ma, Xu; Marchetti, Maria Cristina (SISSA, 2013-03-19)
    Liquid crystals inevitably possess topological defect excitations generated through boundary conditions, applied fields or in quenches to the ordered phase. In equilibrium pairs of defects coarsen and annihilate as the ...
  • Butti, Agostino; Forcella, Davide; Zaffaroni, Alberto (2006-07-26)
    We discuss several examples of non-toric quiver gauge theories dual to Sasaki-Einstein manifolds with U(1)^2 or U(1) isometry. We give a general method for constructing non-toric examples by adding relevant deformations ...
  • Mora, Maria Giovanna; Müller, Stefan (2006-03-16)
    A rigorous derivation is given of a rod theory for a multiphase material,starting from three-dimensional nonlinear elasticity. The stored energy density is supposed to be nonnegative and to vanish exactly on a set consisting ...
  • Alicandro, Roberto; Lazzaroni, Giuliano; Palombaro, Mariapia (2017-01)
    We study continuum limits of discrete models for (possibly heterogeneous) nanowires. The lattice energy includes at least nearest and next-to-nearest neighbour interactions: the latter have the role of penalising changes ...
  • Petcov, Serguey T.; Schwetz, Thomas (2006-03-30)
    The possibility to determine the type of neutrino mass hierarchy by studying atmospheric neutrino oscillations with a detector capable to distinguish between neutrino and antineutrino events, such as magnetized iron ...
  • Bettiol, Piernicola (2006-03-28)
    We prove an existence and uniqueness result for the solutions to the Skorokhod problem on uniformly prox-regular sets through a deterministic approach. This result can be applied in order to investigate some regularity ...
  • Dubrovin, Boris (Scuola Normale Superiore di Pisa, 1991-11)
    We construct flat Riemannian metrics on moduli spaces of algebraic curves with marked meromorphic function. This gives a new class of exact algebraic-geometry solutions to certain non-linear equations in terms of functions ...
  • Gallone, Matteo; Michelangeli, Alessandro (2017)
    The one-particle Dirac Hamiltonian with Coulomb interaction is known to be realised, in a regime of large (critical) couplings, by an infinite multiplicity of distinct self-adjoint operators, including a distinguished ...
  • Casati, Matteo (2015)
    Euler's equations for a two-dimensional system can be written in Hamiltonian form, where the Poisson bracket is the Lie-Poisson bracket associated to the Lie algebra of divergence free vector fields. We show how to derive ...
  • Iandoli, Felice; Scandone, Raffaele (2017-03-30)
    The study of dispersive properties of Schrödinger operators with point interactions is a fundamental tool for understanding the behavior of many body quantum systems interacting with very short range potential, whose ...
  • Caponi, Maicol; Sapio, Francesco (2019-04-30)
    In this paper we prove the existence of solutions for a class of viscoelastic dynamic systems on time-dependent cracked domains, with possibly degenerate viscosity coefficients. Under stronger regularity assumptions we ...
  • Bonaschi, Giovanni A.; Van Meurs, Patrick; Morandotti, Marco (SISSA, 2015)
    The gradient flow structure of the model introduced in [CG99] for the dynamics of screw dislocations is investigated by means of a generalised minimising-movements scheme approach. The assumption of a finite number of ...
  • Dell'Antonio, Gianfausto; Michelangeli, Alessandro (SISSA, 2014)
    We discuss how the vertex boundary conditions for the dynamics of a quantum particle constrained on a graph emerge in the limit of the dynamics of a particle in a tubular region around the graph (\fat graph") when the ...
  • Panico, Giuliano; Wulzer, Andrea (2007-05-15)
    We apply the holographic method to 5D gauge theories on the warped interval. Our treatment includes the scalars associated with the fifth gauge field component, which appear as 4D Goldstone bosons in the holographic effective ...
