LIGO Seminar

                        Abstract 
The search for non-Newtonian forces has been pursued following many
different paths. Recently it was suggested that hypothetical chameleon
interactions, which might explain the mechanisms behind dark energy, could
be detected in a high-precision force measurement. In such an experiment,
interactions between parallel plates kept at constant separation could be
measured as a function of the pressure of an ambient gas, thereby
identifying chameleon interactions by their unique inverse dependence on the local mass density.

During the past years we have been developing a new kind of setup complying with the

stringent requirements of the proposed experiment. In this talk, I will discuss

the idea behind the experiment, the setup, and the measurement method that will be used to test the chameleon theory.  

We plan to broadcast these talks using TeamSpeak. Use a sub-channel of

LIGO Lab called "LIGO Seminar", which is not password protected.
