Asymptotic search for ground states of SU(2) matrix theory. (English) Zbl 0937.81057

The time-honored \(N=16\) supersymmetric gauge quantum mechanics has recently been identified as describing the dynamics of interacting \(D0\)-branes which reviewed the interest in this model. The authors introduce a complete set of gauge-invariant bosonic and fermionic variables and propose a generalized Born-Oppenheimer approximation in their search for normalizable asymptotic solutions of zero energy, though the method provides only candidates for possible ground states since their global stability has not yet been tested. The candidates include one particular state which is a singlet under the group Spin(9) which lends support to a conjecture by E. Witten and others.
