Cosmology of Nonlinear Oscillations

The nonlinear oscillations of a scalar field are shown to have cosmological equations of state with w = p/ρ ranging from −1 < w < 1. We investigate the possibility that the dark energy is due to such oscillations. ∗[email protected]

Nonlinear electric metamaterials

We propose and design a new type of nonlinear metamaterials exhibiting a resonant electric response at microwave frequencies. By introducing a varactor diode as a nonlinear element within each resonator, we are able to shift the frequency of the electric mode stop band by changing the incident power without affecting the magnetic response. These elements could be combined with the previously de...

Nonlinear Damping of Injection Oscillations

General analytical procedure for determination of the transverse feedback system parameters with a nonlinear regime of injection oscillations damping in circular accelerators and colliders is described. For this feedback loop the dependence between the kick value in the deflector and the beam deviation at the pick-up location is a nonlinear function. The beam dynamic nonlinear equation of the t...
