Type IIA orientifolds and orbifolds on non-factorizable tori
Tetsuji Kimura, Mitsuhisa Ohta, Kei-Jiro Takahashi
We investigate Type II orientifolds on non-factorizable torus with and without its oribifolding. We explicitly calculate the Ramond-Ramond tadpole from string one-loop amplitudes,…

Three-Family Models from a Heterotic Orbifold on the E_6 Root Lattice
Kei-Jiro Takahashi
We classify N=1 orbifolds on the E_6 root lattice and investigate explicit model constructions on the Z_3xZ_3 orbifold in heterotic string theory. Interestingly some of the twisted…
