On asymptotic Hamiltonian for \(\text{SU}(N)\) Matrix theory. (English) Zbl 0955.81042

Summary: We compute the leading contribution to the effective Hamiltonian of SU\((N)\) matrix theory in the limit of large separation. We work with a gauge fixed Hamiltonian and use generalized Born-Oppenheimer approximation, extending the recent work of Halpern and Schwartz for SU(2). The answer turns out to be a free Hamiltonian for the coordinates along the flat directions of the potential. Applications to finding ground state candidates and calculation of the correction (surface) term to Witten index are discussed.
