15. The birth of "Tor Vergata" Fabry-Pérot interferometer

20/01/2012, 16:40

Fabry-Pérot tunable filters are of great interest in high spectral resolution imaging for both ground-based and space astronomical observations. The prototype here presented has been developed as part of the study for the narrow band channel of the ADAHELI mission. The ADvanced Astronomy for HELIophysics (ADAHELI) is a solar satellite designed to investigate the dynamics of solar atmosphere...

17. Structural, electronic and optical properties of the two isomers of Si(111)2x1

20/01/2012, 17:00

The Si(111)2x1 surface, which appears on cleaved surfaces at low and room temperature, has been among the most studied semiconductor surfaces ever. Although apparently simple, it shows several intriguing and not completely understood features. The atomic structure of the Si(111)2x1 surface has been known for decades to consist of Pandey chains [1], that can tilt with two possible directions,...

18. Gibbs and Helmholtz ensembles for flexible and semiflexible polymers with elastic bonds

20/01/2012, 17:20

Stretching experiments on arbitrarily long single molecules opened the way for studying the statistical mechanics of small systems. In many cases in which the thermodynamic limit is not satisfied, different macroscopic boundary conditions, corresponding to different statistical mechanics ensembles, yield different macroscopic force-displacement curves, or constitutive equations. We formulate...
