The Intimate Link Between Accretion and BELR
F. Nicastro, A. Martocchia, G. Matt
In this paper I present evidence suggesting that the absence or presence of Hidden Broad Line Regions (HBLRs) in Seyfert 2 galaxies is regulated by the rate at which matter accrete…
Nonlinear Tight-Binding Approximation for Bose-Einstein Condensates in a Lattice
Augusto Smerzi, Andrea Trombettoni
The dynamics of Bose-Einstein condensates trapped in a deep optical lattice is governed by a discrete nonlinear equation (DNL). Its degree of nonlinearity and the intersite hopping…
The initial boundary value problem on the segment for the Nonlinear Schrödinger equation; the algebro-geometric approach. I
P. G. Grinevich, P. M. Santini
This is the first of a series of papers devoted to the study of classical initial-boundary value problems of Dirichlet, Neumann and mixed type for the Nonlinear Schrödinger equatio…
Generalized Network Growth: from Microscopic Strategies to the Real Internet Properties
Guido Caldarelli, Paolo De Los Rios, Luciano Pietronero
In this paper we present a generalized model for network growth that links the microscopical agent strategies with the large scale behavior. This model is intended to reproduce the…
Octupole response and stability of spherical shape in heavy nuclei
V. I. Abrosimov, O. I. Davidovskaya, A. Dellafiore +1
The isoscalar octupole response of a heavy spherical nucleus is analyzed in a semiclassical model based on the linearized Vlasov equation. The octupole strength function is evaluat…
Quasar Evolution Driven by Galaxy Encounters in Hierarchical Structures
N. Menci, A. Cavaliere, A. Fontana +3
We link the evolution of the galaxies in the hierarchical clustering scenario with the changing accretion rates of cold gas onto the central massive black holes that power the quas…
