Effective mass and symmetry breaking in the IKKT matrix model from compactification
Samuel Laliberte
The IKKT model is a promising candidate for a non-perturbative description of Type IIB superstring theory. It is known from analytic approaches and numerical simulations that the I…

IKKT thermodynamics and early universe cosmology
Samuel Laliberte, Suddhasattwa Brahma
Matrix theory is a proposed non-perturbative definition of superstring theory in which space is emergent. Recently, it was shown that space-time can emerge with a scale-invariant s…

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…
