Jens Hoppe (KTH, Sweden), Ki-Myeong Lee (KIAS, Korea)

TL;DR
This paper investigates new 1/2 BPS configurations in BMN matrix theory, analyzing their stability, angular momentum limits, and explicitly constructing novel solutions with potential implications for understanding nonabelian structures.
Contribution
It introduces new BPS configurations in BMN matrix theory, analyzes their fluctuation behavior, and explores the maximal angular momentum limits of nonabelian solutions.
Findings
Nonabelian BPS configurations emerge from fluctuations near abelian solutions.
Irreducible nonabelian configurations have a maximal angular momentum of order N^3.
New explicit BPS configurations are constructed and analyzed.
Abstract
We explore the 1/2 BPS configurations in BMN matrix theory with SO(3) angular momentum of symmetry. The fluctuation analysis of the BPS configurations near the abelian solutions and also the fuzzy two sphere vacua reveals how nonabelian BPS configurations emerge. Especially the irreducible nonabelian configurations seem to have the maximal angular momentum of order , beyond which they collapse to abelian ones. We also find some new BPS configurations explicitly.
