Comment on ``Electron-phonon Vertex in the Two-dimensional One-band Hubbard Model''
B. Cerruti, E. Cappelluti, L. Pietronero
In cond-mat/0306131 Huang {\em et al.} reported for the first time a numerical evidence for the predominance of small phonon momenta in the electron-phonon coupling induced by elec…
Nonadiabatic high- superconductivity in FET doped fullerenes
P. Paci, E. Cappelluti, C. Grimaldi +2
The validity of some experimental data on which the paper was based have been questioned by the report of the Committee of the Bell Labs released on September 2002.
Fractal structures and the large scale distribution of galaxies
Luciano Pietronero, Francesco Sylos Labini
Galaxy structures are certainly fractal up to a certain crossover scale λ_0. A clear determination of such a scale is still missing. Usually, the conceptual and practical implicati…
Reconstructing the cosmological puzzle
Luciano Pietronero, Francesco Sylos Labini
In the debate about galaxy correlation there are different questions which can be addressed separately: Which are the statistical methods able to properly detect scale invariance a…
Fractal Growth with Quenched Disorder
L. Pietronero, R. Cafiero, A. Gabrielli
In this lecture we present an overview of the physics of irreversible fractal growth process, with particular emphasis on a class of models characterized by {\em quenched disorder}…
Scale invariance in galaxy structures: general concepts and application to the most recent data
Luciano Pietronero, Francesco Sylos Labini
The debate on the correlation properties of galaxy structures has having an increasing interest during the last year. In this lecture we discuss the claims of different authors who…
