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…
Stringy Resolutions of Null Singularities
Michal Fabinger, Simeon Hellerman
We study string theory in supersymmetric time-dependent backgrounds. In the framework of general relativity, supersymmetry for spacetimes without flux implies the existence of a co…
Lattice Gauge Theories Have Gravitational Duals
Simeon Hellerman
In this paper we examine a certain threebrane solution of type IIB string theory whose long-wavelength dynamics are those of a supersymmetric gauge theory in 2+1 continuous and 1 d…
Realizing the Quantum Hall System in String Theory
Simeon Hellerman, Leonard Susskind
In a recent paper Bernevig, Brodie, Susskind and Toumbas constructed a brane realization of the Quantum Hall fluid. Since then it has been realized that the Quantum Hall system is…
