Instantons on Calabi-Yau and hyper-Kähler cones
Jakob C. Geipel, Marcus Sperling
The instanton equations on vector bundles over Calabi-Yau and hyper-Kähler cones can be reduced to matrix equations resembling Nahm's equations. We complement the discussion of Her…
Higher spin gauge theory on fuzzy
Marcus Sperling, Harold C. Steinacker
We examine in detail the higher spin fields which arise on the basic fuzzy sphere in the semi-classical limit. The space of functions can be identified with functions on cl…
Covariant 4-dimensional fuzzy spheres, matrix models and higher spin
Marcus Sperling, Harold C. Steinacker
We study in detail generalized 4-dimensional fuzzy spheres with twisted extra dimensions. These spheres can be viewed as -equivariant projections of quantized coadjoint orbi…
Tunnelling in Dante's Inferno
Kazuyuki Furuuchi, Marcus Sperling
We study quantum tunnelling in Dante's Inferno model of large field inflation. Such a tunnelling process, which will terminate inflation, becomes problematic if the tunnelling rate…
