A semidefinite programming bootstrap is formulated for Euclidean two-point correlators in quantum mechanics, yielding rigorous bounds and low-lying spectrum extraction in the ungauged one-matrix model.
The reduced density matrix bootstrap yields rigorous lower bounds on superfluid stiffness for quantum geometric nesting models, relating stiffness to pair mass and showing enhancement from added magnetic interactions.
