Gravitational Stability and Extra Timelike Dimensions
Tachyonic Kaluza-Klein modes normally appear from the compactification of extra timelike dimensions with scale L and lead to some instabilities of physical systems. We calculate the contribution of tachyonic gravitons to the self energies of spherical massive bodies of radius R and discuss their possible gravitational stability. We find that some spherical bodies can be stable at critical radii...
متن کاملGravitational Stability and Screening Effect from D Extra Timelike Dimensions
We study (3+ 1)+D dimensional spacetime, where D extra dimensions are timelike. Compactification of the D timelike dimensions leads to tachyonic Kaluza-Klein gravitons. We calculate the gravitational self-energies of massive spherical bodies due to the tachyonic exchange, discuss their stability, and find that the gravitational force is screened in a certain number of the extra dimensions. We a...
متن کاملGravitational Stability and Screening Effect from Extra Timelike Dimensions
We discuss extra timelike dimensions and their effects on the gravitational stability of spherical massive bodies. Here we specifically report our results for the case of one extra timelike dimension where we have made analytically rigorous investigations on the tachyonic graviton exchange due to the infinite tower of the Kaluza-Klein mode. With the scale L of the extra timelike dimension we fi...
متن کاملRubakov, Free energy of an SU(2) monopole-antimonopole pair, Phys. Rev. D63
We present a high-statistic numerical study of the free energy of a monopole-antimonopole pair in pure SU(2) theory. We find that the monopole-antimonopole interaction potential exhibits a screened behavior, as one would expect in presence of a monopole condensate. Screening occurs both in the low-temperature, confining phase of the theory, and in the high-temperature deconfined phase, with no ...
متن کاملGravitational Lensing And Extra Dimensions
We study gravitational lensing and the bending of light in low energy scale (MS) gravity theories with extra space-time dimensions n. We find that due to the presence of spin-2 Kaluza-Klein states from compactification, a correction to the deflection angle with a strong quadratic dependence on the photon energy is introduced. No deviation from the Einstein General Relativity prediction for the ...
