Topology-Induced Critical Current Enhancement in Josephson Networks
P. Silvestrini, R. Russo, V. Corato +7
We investigate the properties of Josephson junction networks with inhomogeneous architecture. The networks are shaped as "quare comb" planar lattices on which Josephson junctions l…
Conductance quantization in etched Si/SiGe quantum point contacts
G. Scappucci, L. Di Gaspare, E. Giovine +3
We fabricated strongly confined Schottky-gated quantum point contacts by etching Si/SiGe heterostructures and observed intriguing conductance quantization in units of approximately…
Log-parabolic spectra and particle acceleration in blazars. III: SSC emission in the TeV band from Mkn 501
E. Massaro, A. Tramacere, M. Perri +2
Curved broad-band spectral distributions of non-thermal sources like blazars are described well by a log-parabolic (LP) law where the second degree term measures the curvature. LP…
INTEGRAL high energy behaviour of 4U 1812-12
A. Tarana, A. Bazzano, P. Ubertini +5
The low mass X-ray binary system 4U 1812-12 was monitored with the INTEGRAL observatory in the period 2003-2004 and with BeppoSAX on April 20, 2000. We report here on the spectral…
Normal-fault stress and displacement through finite-element analysis
Antonietta Megna, Salvatore Barba, Stefano Santini
We compute displacement and stress due to a normal fault by means of two-dimensional plane-strain finite-element analysis. To do so, we apply a system of forces to the fault nodes…
The Long Term Optical Variability of the BL Lac object S5 0716+714: Evidence for a Precessing Jet
R. Nesci, E. Massaro, C. Rossi +3
We present the historic light curve of the BL Lac object S5 0716+714, spanning the time interval from 1953 to 2003, built using Asiago archive plates and our recent CCD observation…
