Loop Corrected D-branes Stability Conditions
Chen-gang Zhou
In type-II string theory compactifications on Calabi-Yau manifolds, topological string theory partition functions give a class of exact F-terms in the four-dimensional effective ac…
Branes wrapping Black Holes
Sumit R. Das, Stefano Giusto, Samir D. Mathur +3
We examine the dynamics of extended branes, carrying lower dimensional brane charges, wrapping black holes and black hole microstates in M and Type II string theory. We show that t…
On Ricci flat Supermanifolds
Chengang Zhou
We study the Ricci flatness condition on generic supermanifolds. It has been found recently that when the fermionic complex dimension of the supermanifold is one the vanishing of t…
Chirality Change in String Theory
M. R. Douglas, C-G. Zhou
It is known that string theory compactifications leading to low energy effective theories with different chiral matter content ({\it e.g.} different numbers of standard model gener…
Deformation Quantization and Quantum Field Theory on Curved Spaces: the Case of Two-Sphere
Chengang Zhou
We study the scalar quantum field theory on a generic noncommutative two-sphere as a special case of noncommutative curved space, which is described by the deformation quantization…
