BFSS Matrix Model Cosmology: Progress and Challenges
Suddhasattwa Brahma, Robert Brandenberger, Samuel Laliberte
We review a proposal to obtain an emergent metric space-time and an emergent early universe cosmology from the BFSS matrix model. Some challenges and directions for future research…
Spontaneous symmetry breaking in the BFSS model: Analytical results using the Gaussian expansion method
Suddhasattwa Brahma, Robert Brandenberger, Samuel Laliberte
We apply the Gaussian expansion method to the BFSS matrix model in the high temperature limit. When the (Euclidean) BFSS action is expanded about a Gaussian ansatz, it is shown tha…
Emergent Metric Space-Time from Matrix Theory
Suddhasattwa Brahma, Robert Brandenberger, Samuel Laliberte
The IKKT matrix model yields an emergent space-time. We further develop these ideas and give a proposal for an emergent metric. Based on previous numerical studies of this model, w…
Emergent Early Universe Cosmology from BFSS Matrix Theory
Suddhasattwa Brahma, Robert Brandenberger, Samuel Laliberte
The BFSS matrix model is a suggested non-perturbative definition of string theory. Starting from a thermal state of this matrix model, we show how space and time can emerge dynamic…
