Scale and Conformal Invariance in Heterotic -Models
Georgios Papadopoulos
We demonstrate that all perturbative scale invariant heterotic sigma models with a compact target space are conformally invariant. The proof, presented in detail for up to an…
Scale and Conformal Invariance in 2d Sigma Models, with an Application to N=4 Supersymmetry
Georgios Papadopoulos, Edward Witten
By adapting previously known arguments concerning Ricci flow and the c-theorem, we give a direct proof that in a two-dimensional sigma-model with compact target space, scale invari…
Separability, plane wave limits and black holes
G. Papadopoulos
We present a systematic construction of the Penrose coordinates and plane wave limits of spacetimes for which both the null Hamilton-Jacobi and geodesic equations separate. The met…
On supersymmetric AdS6 solutions in 10 and 11 dimensions
J. B. Gutowski, G. Papadopoulos
We prove a non-existence theorem for smooth, supersymmetric, warped AdS6 solutions with connected, compact without boundary internal space in D=11 and (massive) IIA supergravities.…
Patching DFT, T-duality and Gerbes
P. S. Howe, G. Papadopoulos
We clarify the role of the dual coordinates as described from the perspectives of the Buscher T-duality rules and Double Field Theory. We show that the T-duality angular dual coord…
Anomaly Corrected Heterotic Horizons
A. Fontanella, J. B. Gutowski, G. Papadopoulos
We consider supersymmetric near-horizon geometries in heterotic supergravity up to two loop order in sigma model perturbation theory. We identify the conditions for the horizons to…
