# Dynamics and stability of light-like tachyon condensation

@article{Barnaby2008DynamicsAS, title={Dynamics and stability of light-like tachyon condensation}, author={Neil Barnaby and David J. Mulryne and Nelson J. Nunes and Patrick A. Robinson}, journal={Journal of High Energy Physics}, year={2008}, volume={2009}, pages={018-018} }

Recently, Hellerman and Schnabl considered the dynamics of unstable D-branes in the background of a linear dilaton. Remarkably, they were able to construct light-like tachyon solutions which interpolate smoothly between the perturbative and nonperturbative vacua, without undergoing the wild oscillations that plague time-like solutions. In their analysis, however, the full structure of the initial value problem for the nonlocal dynamical equations was not considered. In this paper, therefore, we…
