Non--power law behavior of the radial profile of phase--space density of halos
A. Del Popolo
We study the pseudo phase-space density, , of CDM dark matter halos with and without baryons (baryons+DM, and pure DM), by using the model introduced in Del Popolo…
Ballistic transport properties across nonuniform strain barriers in graphene
F. M. D. Pellegrino, G. G. N. Angilella, R. Pucci
We study the effect of uniaxial strain on the transmission and the conductivity across a strain-induced barrier in graphene. At variance with conventional studies, which consider s…
Exploring the anomaly in the interaction cross section and matter radius of 23O
R. Kanungo, A. Prochazka, M. Uchida +37
New measurements of the interaction cross sections of 22,23O at 900A MeV performed at the GSI, Darmstadt are reported that address the unsolved puzzle of the large cross section pr…
Topological order in 1D Cluster state protected by symmetry
Wonmin Son, Luigi Amico, Vlatko Vedral
We demonstrate how to construct the Z2*Z2 global symmetry which protects the ground state degeneracy of cluster states for open boundary conditions. Such a degeneracy ultimately ar…
On the Weak-Lefschetz property for Artinian Gorenstein algebras
Alfio Ragusa, Giuseppe Zappala
We deal with the Weak Lefschetz property (WLP) for Artinian standard graded Gorenstein algebras of codimension We prove that many Gorenstein sequences force the WLP for such a…
Understanding mobility in a social petri dish
Michael Szell, Roberta Sinatra, Giovanni Petri +2
Despite the recent availability of large data sets on human movements, a full understanding of the rules governing motion within social systems is still missing, due to incomplete…
