Welcome to the home page of the Noise in Physical System (NiPS) Laboratory at the Physics Department of the University of Perugia, Italy.

Our laboratory has a long-standing tradition in studying physical systems in the presence of noise. Our interest ranges from stochastic nonlinear dynamics modelling to thermal noise measurements. We are interested in approaching both theoretical and experimental aspects of the research activity.
In the following please find some example of the studies carried on in our laboratory together with links to our ongoing activity.

The first fused Silica monolithic suspension for Advanced Virgo

Thermal noise in mirror suspension  is the most severe limit to the low-frequency sensitivity of first generation interferometric gravitational wave detectors. In order to minimize the pendulum thermal noise, a monolithic suspension, using fused silica as a low dissipation material, has been developed for Advanced Virgo.

Now the first monolithic suspension has been realized last Thursday June 11st, thanks to a strong collaboration between the INFN groups of Perugia, Firenze and Roma1, that also collaborate in the development of such key components of the mirror suspensions. -
