Dynamical Dimension Change in Supercritical String Theory
Simeon Hellerman, Xiao Liu
We study tree-level solutions to heterotic string theory in which the number of spacetime dimensions 10+n changes dynamically due to closed string tachyon condensation. Taking the…

On the Landscape of Superstring Theory in D > 10
Simeon Hellerman
We study a family of unstable heterotic string theories in more than ten dimensions which are connected via tachyon condensation to the ten-dimensional supersymmetric vacuum of het…
