Description

I will present lattice investigations of the Berenstein--Maldacena--Nastase deformation of maximally supersymmetric Yang--Mills quantum mechanics, focusing on its phase diagram in the plane of the temperature $T$ and deformation parameter $\mu$. By considering values of the dimensionless coupling $g=\lambda /{\mu }^3$ spanning more than two orders of magnitude, we find results for the deconfinement $T/\mu$ that interpolate between the $g\to 0$ perturbative prediction and recent large-$N$ dual supergravity calculations in the limit $g\to \mathrm{\infty }$. We analyze multiple lattice sizes up to $N_{\tau }=24$ and numbers of colors up to $N=16$, allowing initial checks of the large-$N$ continuum limit.
