Modified gravity at large scales on quantum spacetime in the IKKT model

Harold C. Steinacker

The gravitational dynamics of 3+1 dimensional covariant quantum spacetime in the IKKT or IIB matrix model is studied at one loop, combining the Yang-Mills-type matrix action with t…

Spatially flat cosmological quantum spacetimes

Christian Gaß, Harold C. Steinacker

We recently described a cosmological quantum spacetime of vanishing spatial curvature, which can be considered as background for the IKKT matrix model, assuming that the resulting…

Dynamical Covariant Quantum Spacetime with Fuzzy Extra Dimensions in the IKKT model

Alessandro Manta, Harold C. Steinacker

We consider general FLRW covariant quantum spacetimes with fuzzy extra dimensions as classical solutions of the IKKT mat…

General Relativity in IIB Matrix Model

Pei-Ming Ho, Hikaru Kawai, Harold C. Steinacker

The matrix models are non-perturbative formulations of string theory, from which many believe that spacetime arises. The matrix fluctuations around the spacetime thus created shoul…

Quantum Geometry of Data

Alexander G. Abanov, Luca Candelori, Harold C. Steinacker +9

We demonstrate how Quantum Cognition Machine Learning (QCML) encodes data as quantum geometry. In QCML, features of the data are represented by learned Hermitian matrices, and data…

Quantum Cognition Machine Learning for Forecasting Chromosomal Instability

Giuseppe Di Caro, Vahagn Kirakosyan, Alexander G. Abanov +11

The accurate prediction of chromosomal instability from the morphology of circulating tumor cells (CTCs) enables real-time detection of CTCs with high metastatic potential in the c…
