Holographic non-Gaussianities in general single-field inflation
Hiroshi Isono, Toshifumi Noumi, Gary Shiu +2
We use holographic techniques to compute inflationary non-Gaussianities for general single-field inflation, including models with a non-trivial sound speed. In this holographic app…

Nonlocal N=1 Supersymmetry
Tetsuji Kimura, Anupam Mazumdar, Toshifumi Noumi +1
We construct supersymmetric nonlocal theories in four dimension. We discuss higher derivative extensions of chiral and vector superfields, and write down generic fo…
