If dark energy is hiding in our midst in the form of hypothetical particles called “chameleons,” Holger Müller and his team at UC Berkeley plan to flush them out.The results of an experiment reported ...
Cambridge, Mass. – January 28, 2014 – Scientists at Harvard University and the Marine Biological Laboratory (MBL) hope new understanding of the natural nanoscale photonic device that enables a small m...
We model the chameleon effect on cosmological statistics for the modified gravity f(R) model of cosmic acceleration. The chameleon effect, required to make the model compatible with local tests of gra...

A scalar field is a favorite candidate for the particle responsible for dark energy. However, few theoretical means exist that can simultaneously explain the observed acceleration of the Universe and ...
Chameleon mechanism is a new model, which introduced to provide a mechanism for exhibiting accelerating universe. It has several interesting aspects, such as field dependence on the local matter dens...
