2D fuzzy Anti-de Sitter space from matrix models
Danijel Jurman, Harold Steinacker
We study the fuzzy hyperboloids AdS^2 and dS^2 as brane solutions in matrix models. The unitary representations of SO(2,1) required for quantum field theory are identified, and exp…
Generalized Fuzzy Torus and its Modular Properties
Paul Schreivogl, Harold Steinacker
We consider a generalization of the basic fuzzy torus to a fuzzy torus with non-trivial modular parameter, based on a finite matrix algebra. We discuss the modular properties of th…
Compactified rotating branes in the matrix model, and excitation spectrum towards one loop
Daniel N. Blaschke, Harold C. Steinacker
We study compactified brane solutions of type R^4 x K in the IIB matrix model, and obtain explicitly the bosonic and fermionic fluctuation spectrum required to compute the one-loop…
Brane compactifications and 4-dimensional geometry in the IKKT model
Alexios P. Polychronakos, Harold Steinacker, Jochen Zahn
We study in detail certain brane solutions with compact extra dimensions M^4 x K in the IKKT matrix model, with K being a two-dimensional rotating torus embedded in R^6. We focus o…
