D-branes on Orbifolds with Discrete Torsion And Topological Obstruction
TL;DR: In this article, it was shown that the correspondence between fractional branes and Ramond-Ramond fields follows in an interesting fashion from the way that discrete torsion is implemented on open and closed strings.
Discrete torsion, covering groups and quiver diagrams
TL;DR: In this paper, the authors present a simple algorithm to study the gauge theory data of D-brane probes on a generic orbifold G with discrete torsion turned on.
Non-geometric backgrounds based on topological interfaces
Yuji Satoh,Yuji Sugawara +1 more
TL;DR: In this article, the authors study simple models of the world-sheet CFTs describing non-geometric backgrounds based on the topological interfaces, the "gluing condition" of which imposes T-duality-or analogous twists.
Orientifolds with discrete torsion
Matthias Klein,Raul Rabadan +1 more
TL;DR: In this article, the authors show how discrete torsion can be implemented in D=4, N=1 type IIB orientifolds and give the spectrum and tadpole cancellation conditions explicitly.
Discrete torsion, non-abelian orbifolds and the Schur multiplier
TL;DR: In this paper, a classification of SU(n) orbifolds for n = 2,3,4 which permit the turning on of discrete torsion is presented, and a comparison of the quiver theory thereof with that of its covering group, the binary dihedral group, without discrete Torsion, is also performed.

Strings on orbifolds
TL;DR: In this article, the authors considered string propagation on the quotient of a flat torus by a discrete group and obtained an exactly soluble and more or less realistic method of string compactification.

A Pair of Calabi-Yau manifolds as an exactly soluble superconformal theory
TL;DR: In this paper, the prepotentials and geometry of the moduli spaces for a Calabi-Yau manifold and its mirror were derived and all the sigma model corrections to the Yukawa couplings and moduli space metric were obtained.

Modular invariance and discrete torsion on orbifolds
TL;DR: In this article, it was shown that fermionic left-right level matching is necessary and sufficient to guarantee modular invariance to 1-loop order in orbifold compactification of heterotic string.
