Witten index from lattice simulation
Witten index lattice simulation

2011/1/6
I propose a method for measuring the Witten index using a lattice simulation. The index is useful to discuss spontaneous breaking of supersymmetry. As a test of the method, I also report some numerica...
Index Theorem and Overlap Formalism with Naive and Minimally Doubled Fermions
Index Theorem Overlap Formalism Naive

We present a theoretical foundation for the Index theorem in naive and minimally doubled lattice fermions by studying the spectral flow of a Hermitean version of Dirac operators. We utilize the point ...

We evaluate the superconformal index of the Y^{p,q} quiver gauge theories using Romeslberger's prescription. For the conifold quiver Y^{1,0} we find exact agreement at large N with a previous calculat...
