Supersymmetric compactifications of heterotic strings with fluxes and condensates
Pantelis Manousselis, Nikolaos Prezas, George Zoupanos
We discuss supersymmetric compactifications of heterotic strings in the presence of H-flux and general condensates using the formalism of G-structures and intrinsic torsion. We rev…
Scherk-Schwarz reduction of M-theory on G2-manifolds with fluxes
Gianguido Dall'Agata, Nikolaos Prezas
We analyse the 4-dimensional effective supergravity theories obtained from the Scherk--Schwarz reduction of M-theory on twisted 7-tori in the presence of 4-form fluxes. We implemen…
D-branes and SQCD in Non-Critical Superstring Theory
Angelos Fotopoulos, Vasilis Niarchos, Nikolaos Prezas
Using exact boundary conformal field theory methods we analyze the D-brane physics of a specific four-dimensional non-critical superstring theory which involves the N=2 SL(2)/U(1)…
