Heterotic G_2-manifold compactifications with fluxes and fermionic condensates
Karl-Philip Gemmer, Olaf Lechtenfeld
We consider flux compactifications of heterotic string theory in the presence of fermionic condensates on M_{1,2} times X_7 with both factors carrying a Killing spinor. In other wo…
Heterotic string plus five-brane systems with asymptotic AdS3
Karl-Philip Gemmer, Alexander S. Haupt, Olaf Lechtenfeld +2
We present NS1+NS5-brane solutions of heterotic supergravity on curved geometries. They interpolate between a near horizon AdS3 x X^k x T^{7-k} region and R^{1,1} x c(X^k) x T^{7-k…
Yang-Mills instantons on cones and sine-cones over nearly Kähler manifolds
Karl-Philip Gemmer, Olaf Lechtenfeld, Christoph Nölle +1
We present a unified eight-dimensional approach to instanton equations on several seven-dimensional manifolds associated to a six-dimensional homogeneous nearly Kähler manifold. Th…
