Room temperature GW bar detector with opto-mechanical readout

We present the full implementation of a room-temperature gravitational wave bar detector equipped with an opto-mechanical readout. The mechanical vibrations are read by a Fabry--Perot interferometer whose length changes are compared with a stable reference optical cavity by means of a resonant laser. The detector performance is completely characterized in terms of spectral sensitivity and statistical properties of the fluctuations in the system output signal. The new kind of readout technique allows for wide-band detection sensitivity and we can accurately test the model of the coupled oscillators for thermal noise. Our results are very promising in view of cryogenic operation and represent an important step towards significant improvements in the performance of massive gravitational wave detectors.Comment: 7 figures, submitted to Phys.

Open up Internet Research

Nel 2007 il Times sceglieva l’utente del web come persona dell’anno: Yes, You. You Control the Information Age. Welcome to Your World. Dal 2007 molta acqua sotto i ponti della Rete è passata e, a otto anni da quella copertina, il nuovo mondo è cresciuto in mole e complessità, così come si sono moltiplicati i tentativi da parte della ricerca, pubblica e privata, di mettere ordine nella comprensione dei meccanismi che lo governano. Obiettivo di questa rubrica è fornire alcuni primi riferimenti per orientarsi nel mondo della ricerca e dello studio intorno alla Rete. Ognuno di questi costituisce un hub di collegamento a network e comunità professionali ampie ed accreditate da cui imparare e con cui confrontarsi

The relevance of the theory of fiscal illusion. The case of the Italian tax system

This work analyses the phenomenon of fiscal illusion (Puviani, 1903) in the context of the Italian tax system. Financial (or fiscal) illusion refers to mechanisms which cause a cognitive alteration on the part of the taxpayer regarding the evaluation of the costs and benefits of public policies. Puviani (1903) was the first to classify the different types of financial illusions. He highlighted the main strategies used to hide the real costs of financing public goods and services through taxes (illusions on revenue) or to overestimate their usefulness (illusions on expenditure). The main conclusions of the work are that: (i) from a methodological point of view, there is a connection between Puviani’s theory of fiscal illusion and some of the assumptions of the behavioral approach and (ii) from an operational point of view, it is a useful tool to understand the motives that could have inspired several recent taxes and legislative measures within the Italian tax system. These results support the relevance of Puviani’s theory to the contemporary theory and practice of public finance

Chiral Lagrangians with tensor sources

The implementation of tensor sources in Chiral Lagrangians allows the computation of Green functions and form factors involving tensor currents, that is, quark bilinears of the form \bar{q}_i\sigma^{\mu\nu}q_j. Whereas only four new terms show up at O(p^4), we find around a hundred of them at O(p^6). So it becomes essential to ensure that this set o operators is indeed minimal and non-redundant (i.e., it is a basis). We discuss two phenomenological applications in the context of vector meson resonances and the radiative pion decay.Comment: Talk given at the 4th International Worshop on Quantum ChromoDynamics, Theory and experiment, June 16-20, 2007.

Acyclic orientations with path constraints

Many well-known combinatorial optimization problems can be stated over the set of acyclic orientations of an undirected graph. For example, acyclic orientations with certain diameter constraints are closely related to the optimal solutions of the vertex coloring and frequency assignment problems. In this paper we introduce a linear programming formulation of acyclic orientations with path constraints, and discuss its use in the solution of the vertex coloring problem and some versions of the frequency assignment problem. A study of the polytope associated with the formulation is presented, including proofs of which constraints of the formulation are facet-defining and the introduction of new classes of valid inequalities

Experimental measurement of photothermal effect in Fabry-Perot cavities

We report the experimental observation of the photothermal effect. The measurements are performed by modulating the laser power absorbed by the mirrors of two high-finesse Fabry-Perot cavities. The results are very well described by a recently proposed theoretical model [M. Cerdonio, L. Conti, A. Heidmann and M. Pinard, Phys. Rev. D 63 (2001) 082003], confirming the correctness of such calculations. Our observations and quantitative characterization of the photothermal effect demonstrate its critical importance for high sensitivity interferometric displacement measurements, as those necessary for gravitational wave detection.Comment: 4 pages, 3 figures, submitted to Phys.
