Localized BFSS phases are linked to instability and phase transitions
What the study found The study finds that the recently discovered localized and non-uniform phases of BFSS matrix quantum mechanics can be derived from first principles. It also finds that the uniform BFSS phase corresponds to a black string in a pp-wave background, which is unstable to a Gregory-Laflamme instability. Why the authors say this…
