Spinorial description for Lorentzian -IKKT

Harold C. Steinacker, Tung Tran

We introduce a novel spinorial description for the higher-spin gauge theory induced by the IKKT matrix model on an FLRW spacetime with Lorentzian signature, called Lorentzian $\mat…

Modified Einstein equations from the 1-loop effective action of the IKKT model

Kaushlendra Kumar, Harold C. Steinacker

We derive the equations of motion that arise from the one-loop effective action for the geometry of 3+1 dimensional quantum branes in the IKKT matrix model. These equations are cas…

Interactions in the IKKT matrix model on covariant quantum spacetime

Harold C. Steinacker, Tung Tran

We study the interactions of the higher-spin gauge theory arising from the IKKT matrix model on a covariant quantum FLRW quantum space-time , denote…

One-loop effective action of the IKKT model for cosmological backgrounds

Emmanuele Battista, Harold C. Steinacker

We study cosmological solutions of the IKKT model with FLWR geometry, taking into account one-loop corrections. A previously discussed covariant quantum spacetime is found t…

Spinorial higher-spin gauge theory from IKKT in Euclidean and Minkowski signatures

Harold Steinacker, Tung Tran

We explore the semi-classical relation between the fuzzy 4-hyperboloid and non-compact quantized twistor space at large . This provides two background…

One-loop effective action and emergent gravity on quantum spaces in the IKKT matrix model

Harold C. Steinacker

A detailed derivation of dimensional induced or emergent gravity in the IKKT matrix model at one loop is given, as announced in [1]. The mechanism requires a brane configurat…
