Duality and Infinite Distance Limits in Asymmetric Freely Acting Orbifolds

George Gkountoumis, Chris Hull, Guo-En Nian +1

We use freely acting asymmetric orbifolds of type IIB string theory to construct a class of theories in four dimensions with eight supercharges. Their low energy effective field th…

Asymmetric $Z_{4}$ orbifolds of type IIB string theory revisited

George Gkountoumis

We construct freely acting asymmetric $Z_{4}$ orbifolds of type IIB string theory on $T^{5}$ preserving 24,16 or 8 supercharges in five dimensions. We show that these models a…

Exact moduli spaces for $N = 2, D = 5$ freely acting orbifolds

George Gkountoumis, Chris Hull, Stefan Vandoren

We use freely acting asymmetric orbifolds of type IIB string theory to construct a class of theories in five dimensions with eight supercharges whose moduli spaces for vector multi…

Freely acting orbifolds of type IIB string theory on $T^{5}$

George Gkountoumis, Chris Hull, Koen Stemerdink +1

We study freely acting orbifolds of type IIB string theory on $T^{5}$ that spontaneously break supersymmetry from $N = 8$ to $N = 6, 4, 2$ or 0 in five dimensions. We f…
