The fuzzy 4hyperboloid Hn4 and higherspin in Yang–Mills matrix models
/ Sperling, Marcus ; Steinacker, Harold C.
We consider the SO(4,1) covariant fuzzy hyperboloid Hn4 as a solution of Yang–Mills matrix models, and study the resulting higherspin gauge theory. [...]

Quantized open FRW cosmology from Yang–Mills matrix models
/ Steinacker, Harold C.
We present simple solutions of IKKTtype matrix models describing a quantized homogeneous and isotropic cosmology with k=−1 , finite density of microstates and a resolved Big Bang. [...]

String states, loops and effective actions in noncommutative field theory and matrix models
/ Steinacker, Harold C.
Refining previous work by Iso, Kawai and Kitazawa, we discuss bilocal string states as a tool for loop computations in noncommutative field theory and matrix models. [...]

An extended standard model and its Higgs geometry from the matrix model
/ Steinacker, Harold C. ; Zahn, Jochen
We find a simple brane configuration in the IKKT matrix model which resembles the standard model at low energies, with a second Higgs doublet and righthanded neutrinos. [...]
