Threshold and positive-energy bound states of the BFSS matrix model

OpenAI research collection · 2 manuscripts · Source checked 2026-10-19

OpenAI's result summary

Proves that the undeformed relative SU(N) BFSS model has exactly one normalizable zero-energy state for every finite N ≥ 2, resolving the threshold-bound-state conjecture. For SU(2), a companion proves infinitely many normalizable positive-energy eigenstates with unbounded energies, contradicting the original BFSS paper's exclusion of additional bound states at N = 2.

The unique threshold bound state of the SU(N) BFSS model

For every finite N ≥ 2, we prove that undeformed \mathop{SU}\nolimits (N) BFSS matrix quantum mechanics has exactly one normalizable zero-energy state after removing the center of mass. This establishes the threshold-bound-state conjecture.

Positive eigenvalues of the relative SU(2) BFSS Hamiltonian

We prove that the relative \mathop{SU}\nolimits (2) BFSS Hamiltonian has infinitely many positive eigenvalues tending to infinity, with square-integrable eigenvectors. The operator is defined by closing the gauge-invariant supercharge form. This refutes, at N = 2, the exclusion of normalizable positive-energy states stated in…
