The nonperturbative phase diagram of the bosonic BMN matrix model

Understand

We study the thermal phase transition of the bosonic BMN model which is a mass deformed version of the bosonic part of the BFSS model.

• Our results connect the massless region of the phase diagram described by the bosonic BFSS model with the large-mass region, where the model is analytically solvable.
• We observe that at finite value of the matrix size $N$, the critical region is smeared over a small temperature range.
• The model has a single critical temperature, which arises as the large $N$ limit of two apparent transitions at finite $N$.
