  We investigate the low-energy regime of BFSS quantum mechanics using its
holographic dual. We identify three distinct thermodynamic phases (black holes)
and analyze their thermodynamic properties extensively, including phase
transitions amongst the several phases. While the properties of the canonical
ensemble aligns with existing conjectures on BFSS thermodynamics, we uncover
intriguing and unexpected behavior in the microcanonical ensemble.
Specifically, for sufficiently low energies, we observe the dominance of the
localized phase. Surprisingly, we also identify an energy range where the
non-uniform phase becomes dominant. The transition between these phases is
mediated by a Kol-type topology-changing phenomenon.
