Matrix quantum mechanics theories are at the heart of holography, but only the simple
case of a single matrix has been tractable. We have developed a new method to calculate
the spectrum and expectation values of operators in matrix quantum mechanics, including
with multiple matrices. Firstly, we relate the expectation values of simple operators to those
of more complicated operators. We then impose certain positivity constraints on the longer
operators. This is seen to strongly constrain the simple expectation values. Using this method
we easily reproduce the known solution of single-matrix quantum mechanics, and then go on to
obtain new results on the ground state of two-matrix quantum mechanics. This talk is based
on 2004.10212.
