The phase diagram of an Ising model on a polymerized random surface
ArXiv hep-th/9411013 (1994)
Abstract:
We construct a random surface model with a string susceptibility exponent one quarter by taking an Ising model on a random surface and introducing an additional degree of freedom which amounts to allowing certain outgrowths on the surfaces. Fine tuning the Ising temperature and the weight factor for outgrowths we find a triple point where the susceptibility exponent is one quarter. At this point magnetized and nonmagnetized gravity phases meet a branched polymer phase.The phase diagram of an Ising model on a polymerized random surface

Cosmological Constraints on Perturbative Supersymmetry Breaking
ArXiv hep-ph/9409350 (1994)
Abstract:
We discuss the cosmology of string models with perturbative supersymmetry breaking at a scale of ${\cal O}$(TeV). Such models exhibit Kaluza-Klein like spectra and contain unstable massive gravitinos/gravitons. We find that considerations of primordial nucleosynthesis constrain the maximum temperature following inflation to be not much larger than the supersymmetry breaking scale. This imposes conflicting requirements on the scalar field driving inflation, making it rather difficult to construct a consistent cosmological history for such models.Cosmological Constraints on Perturbative Supersymmetry Breaking
