Recent Progress in Numerical Studies of the Lorentzian IKKT Model

Explore recent advancements in numerical studies of the Lorentzian IKKT matrix model in this 42-minute conference talk from the Workshop on "Large-N Matrix Models and Emergent Geometry" at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the IKKT matrix model's potential as a non-perturbative formulation of superstring theory and its role in studying the dynamical emergence of four-dimensional spacetime. Examine the challenges and recent progress in simulating the Lorentzian model using the Complex Langevin Method (CLM), overcoming the complex action problem. Gain insights into the effects of adding a Lorentz invariant mass term to the original model and understand its implications for superstring theory research.
