The projective to Einstein correspondence and a kink on a wormhole

Waterhouse, Alice ClaireUniversity of Cambridge2020

… a kink solution which is linearly stable, and compare its discrete spectrum to that of the $\phi^4$ kink on $\mathbb{R}^{1,1}$. We present some results on the non–linear resonant coupling between the discrete and continuous spectra in the range of a where there is exactly one discrete mode. …
