In this Journal Club, I will introduce the BFSS matrix quantum mechanics model and discuss its connection to holography and its subtle differences from usual AdS/CFT correspondence. Following that, I will present the BMN model, a supersymmetry-preserving mass deformation of the BFSS model. The strong coupling limit of the BMN model will be analysed, and the results compared with predictions from supergravity. If time permits, I will also explain how to formulate the quantum mechanics bootstrap problem for the BMN model, leveraging input from supersymmetry localisation results.
