On the quantum structure of space-time, gravity, and higher spin in matrix models
Harold C. Steinacker
In this introductory review, we argue that a quantum structure of space-time naturally entails a higher-spin theory, to avoid significant Lorentz violation. A suitable framework is…
Higher-spin kinematics & no ghosts on quantum space-time in Yang-Mills matrix models
Harold C. Steinacker
A classification of bosonic on- and off-shell modes on a cosmological quantum space-time solution of the IIB matrix model is given, which leads to a higher-spin gauge theory. In pa…
Scalar modes and the linearized Schwarzschild solution on a quantized FLRW space-time in Yang-Mills matrix models
Harold C. Steinacker
We study scalar perturbations of a recently found 3+1-dimensional FLRW quantum space-time solution in Yang-Mills matrix models. In particular, the linearized Schwarzschild metric i…
Covariant cosmological quantum space-time, higher-spin and gravity in the IKKT matrix model
Marcus Sperling, Harold C. Steinacker
We discuss a -dimensional covariant quantum space-time describing a FLRW cosmology with Big Bounce, obtained by a projection of the fuzzy hyperboloid . This provide…
