Resolution of Curvature Singularities in Higher Derivative Gravity
Philipp Höffer v. Loewenfeld, Ivo Sachs
We consider possible resolutions of singularities in a contracting anisotropic universe for a class of higher derivative gravity theories. We give evidence that for our models the…
Stringy NJL and Gross-Neveu models at finite density and temperature
Joshua L. Davis, Michael Gutperle, Per Kraus +1
Nonlocal stringy versions of the Nambu-Jona-Lasinio and Gross-Neveu models arise in a certain limit of holographic QCD. We analyze the phase structure at finite density and tempera…
The Low Energy Dynamics of Non-BPS Branes
N. D. Lambert, I. Sachs
In this talk we will discuss the low energy dynamics of non-BPS branes constructed as stable brane/anti-brane pairs at an orbifold. In particular we will determine the effective fi…
On Universality in Black Hole Thermodynamics
I. Sachs
The low energy decay rates of four- and five dimensional dyonic black holes in string theory are equivalently described in terms of an effective near horizon AdS_3 (BTZ) black hole…
Brief Resume of Seiberg-Witten Theory
R. Flume, L. O'Raifeartaigh, I. Sachs
Talk presented by the second author at the Inaugural Coference of the Asia Pacific Center for Theoretical Physics, Seoul, June 1996. The purpose of this note is to give a resume of…
Generalized Gauged Thirring Model on Curved Space-Times
A. Dettki, I. Sachs, A. Wipf
We analyse the interacting theory of charged fermions, scalars, pseuso-scalars and photons propagating in 2-dimensional curved spacetime in detail. For certain values of the coupli…
