A projective Dirac operator on and extended SUSY
Idrish Huet, Julieta Medina
We construct a universal spin Dirac operator on built by projecting left actions and prove its equivalence to the standard right action Dirac operator…
Scalar and Spinor Field Actions on Fuzzy : fuzzy as a bundle over
Julieta Medina, Idrish Huet, Denjoe O'Connor +1
We present a manifestly Spin(5) invariant construction of squashed fuzzy as a fuzzy bundle over fuzzy . We develop the necessary projectors and exhibit the squash…
Probing the fuzzy sphere regularisation in simulations of the 3d λϕ^4 model
Julieta Medina, Wolfgang Bietenholz, Denjoe O'Connor
We regularise the 3d λϕ^4 model by discretising the Euclidean time and representing the spatial part on a fuzzy sphere. The latter involves a truncated expansion of the field in sp…
Field Theory Simulations on a Fuzzy Sphere - an Alternative to the Lattice
Julieta Medina, Wolfgang Bietenholz, Frank Hofheinz +1
We explore a new way to simulate quantum field theory, without introducing a spatial lattice. As a pilot study we apply this method to the 3d λϕ^4 model. The regularisation consist…
Scalar Field Theory on Fuzzy S^4
Julieta Medina, Denjoe O'Connor
Scalar fields are studied on fuzzy and a solution is found for the elimination of the unwanted degrees of freedom that occur in the model. The resulting theory can be interpr…
