In the first part, we propose to generalize the dynamics of Nambu-Goto cosmic strings to include super-conducting currents and higher-order curvature terms. Both super-conducting currents and higher-order curvature terms may drastically influence the gravitation wave signal from cosmic strings that was proposed to be detectable in the case of Nambu-Goto strings by experiments as LIGO, VIRGO and LISA. Dark energy has been suggested as explanation for the observed acceleration of the Universe. The second part of the proposed research project is complementary to usual investigations of Dark Energy in that it aims to study the behaviour of Dark Energy in local gravitational fields, in particular in the gravitational field around a black hole.
