In this paper we study the parallel phase and the coincident phase of D-brane systems with the compactification of one closed modulus. D-brane systems with two phases are described by different 4-folds in terms of Ty...
The D-brane superpotential is very important in the low energy effective theory. As the generating function of all disk instantons from the worldsheet point of view, it plays a crucial role in deriving some important ...
We calculate the D-brane superpotentials for two compact Calabi-Yau manifolds X14(1,1,2,3,7) and Xs (1,1,1,2,3) which are of non-Fermat type in the type II string theory. By constructing the open mirror symmetry, ...

In this paper,we calculate the off-shell superpotential of two Calabi-Yau manifolds with three parameters by integrating the period of the subsystem.We also obtain the Ooguri-Vafa invariants with open mirror symmetry.
The following article has been retracted due to the investigation of complaints received against it. Mr. Mohammadali Ghorbani (corresponding author and also the last author) cheated the authors’ name: Alireza Heidari...
We investigate several Hamiltonians for a free particle in a one-dimensional box, in the context of supersymmetric quantum mechanics. Specifically, we study this problem with the Neumann boundary condition, the period...
