1. The fuzzy 4-hyperboloid Hn4 and higher-spin 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 higher-spin gauge theory. [...]

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

3. 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 bi-local string states as a tool for loop computations in noncommutative field theory and matrix models. [...]

5. 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 right-handed neutrinos. [...]
