(2007-11-07)We deal with a class on nonlinear Schr\"odinger equations \eqref{eq:1} with potentials $V(x)\sim |x|^{-\a}$, $0<\a<2$, and $K(x)\sim |x|^{-\b}$, $\b>0$. Working in weighted Sobolev spaces, the existence of ground states ...
-
(American Physical Society, 2010-02-05)We study the interplay between electron correlation and disorder in the two-dimensional Hubbard model at half-filling by means of a variational wave function that can interpolate between Anderson and Mott insulators. We ...

Group-theoretical classification of BPS and possibly protected states in D=4 conformal supersymmetry(Elsevier, 2012-01-21)We use earlier results on the classification of the positive energy unitary irreducible representations of the N-extended D=4 conformal superalgebras su(2,2/N). These results are applied to the reduction of supersymmetries ...

(Elsevier, 2012-03)Protein synthesis is a tightly regulated, energy-consuming process. The control of mRNA translation into protein is fundamentally important for the fine-tuning of gene expression; additionally, precise translational control ...
-
(IOP Publishing, 2005-07-20)Combining a theoretical model of mass accretion onto a galactic center with a high-resolution $N$-body/SPH simulation, we investigate the formation of an intermediate massive black hole (IMBH) during the hierarchical ...
-
(2007-11-19)We show that the ABC scenario we proposed for the co-evolution of spheroids and QSOs predicts accretion rates and masses of supermassive black holes in sub-mm galaxies in keeping with recent X-ray determinations. These ...

(SISSA, 2013-02)Lo scopo di questa tesi è presentare dei materiali (schede, infografiche, articoli) che potrebbero confluire in un manuale cartaceo, su un sito internet appositamente creato o che potrebbero essere utilizzati anche in ...

(SISSA, 2011-10-28)The plan of this thesis is as follows. Chapt. 1 is devoted to the explanation of the main theoretical tool of our work, namely the GVM and GA. After introducing their earliest formulation by Martin C. Gutzwiller, we discuss ...
-
(2007-11-05)We introduce a novel extension of the Gutzwiller variational wavefunction able to deal with insulators that escape any mean-field like description, as for instance non-magnetic insulators. As an application, we study the ...
-
(2008-08-25)We analyze the ground-state properties of strongly-correlated electrons coupled with phonons by means of a generalized Gutzwiller wavefunction which includes phononic degrees of freedom. We study in detail the paramagnetic ...
-
(American Physical Society, 2010-03-03)We introduce a method that allows for the calculation of quasi-particle spectra in the GW approximation, yet avoiding any explicit reference to empty one-electron states. This is achieved by expressing the irreducible ...

(2008-08-26)We show how the argument exploited by Galaverni & Sigl in Phys. Rev. Lett., 100, 021102 (2008) (see also arXiv:0708.1737) to constrain Lorentz invariance violation (LV) using Ultra-High-Energy photon non observation by the ...

(SISSA Library, 2002)Given a regular function $H\colon\mathbb{R}^{3}\to\mathbb{R}$, we look for $H$-bubbles, that is, regular surfaces in $\mathbb{R}^{3}$ parametrized on the sphere $\mathbb{S}+^{2}$ with mean curvature $H$ at every point. ...

(SISSA Library, 1995)h-deformation of (graded) Hopf algebra of functions on supergroup GL(1|1) is introduced via a contration of GL_q (1|1). The deformation parameter h is odd (grassmann). Related differential calculus on h-superplane is presented.

(Revista de neurologia, 2005-09-01)INTRODUCTION: It is amazing how all normal children, systematically exposed to a natural language, speak using well-formed sentences by the time they are about 3 years old. This is a universally observed fact that is made ...
-
(Springer, 2004)We discuss multi-hadron production in both inelastic neutrino-nucleon interactions in the current fragmentation region and neutrino-nucleus collisions in the target fragmentation region. Our analysis, carried out within ...
