Abstract
We present a new and fundamental approach for generating rapidly convergent lower and upper bounds to the ground-state energy of a bosonic system, . The bosonic ground-state wave function defines a moments problem because it both is nonnegative and exhibits rapid asymptotic decrease. Through the use of the Hankel-Hadamard determinant inequalities associated with this moments problem one can constrain through exponentially convergent bounds. Extensions to excited bosonic states and fermionic systems are briefly outlined.
