Localized gravity in non-compact superstring models
Emmanuel Kohlprath, Pierre Vanhove
We discuss a string-theory-derived mechanism for localized gravity, which produces a deviation from Newton's law of gravitation at cosmological distances. This mechanism can be rea…
Induced gravity in Z_N orientifold models
Emmanuel Kohlprath
We consider non-compact Z_N orientifold models of type IIB superstring theory with four-dimensional gravity induced on a set of coincident D3-branes. For the models with odd N the…
Renormalization of the Planck mass for type II superstrings on symmetric orbifolds
Emmanuel Kohlprath
We compute the one-loop renormalization of the Planck mass for type II string theories compactified to four dimensions on symmetric orbifolds that preserve supersymmet…
Schwinger terms in gravitation in two dimensions as a consequence of the gravitational anomaly
Emmanuel Kohlprath
We compute the Schwinger term in the gravitational constraints in two dimensions, starting from the path integral in Hamiltonian form and the Einstein anomaly.
Two-dimensional gravitational anomalies, Schwinger terms and dispersion relations
R. A. Bertlmann, E. Kohlprath
We are dealing with two-dimensional gravitational anomalies, specifically with the Einstein anomaly and the Weyl anomaly, and we show that they are fully determined by dispersion r…
Schwinger terms in two-dimensional gravitation and Kallen's method
R. A. Bertlmann, E. Kohlprath
We evaluate the gravitational Schwinger terms for the specific two-dimensional model of Weyl fermions in a gravitational background field using a technique introduced by Kallen and…
