A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of $10^{-29}ecdot$cm by using polarized magic momentum $0.7$~GeV/c protons in an all-electric storage ring. Systematic errors relevant to the
experiment are discussed and techniques to address them are presented. The measurement is sensitive to new physics beyond the Standard Model at the scale of 3000~TeV.
We find the conditions upon the amplitude and frequency of an external electromagnetic field at which the dipole moment of a Bergman-Stockman spaser oscillates in antiphase with the field. For these values of the amplitude and frequency the losses in
metal nanoparticles is exactly compensated of by gain. This shows that spasers may be used as inclusions in designing lossless metamaterials.
