On the use of the Discrete Variable Representation Basis in Nuclear
Physics
   [PDF]

Aurel Bulgac, Michael McNeil Forbes
The discrete variable representation (DVR) basis is nearly optimal for numerically representing wave functions in nuclear physics: Suitable problems enjoy exponential convergence, yet the Hamiltonian remains sparse. We show that one can often use smaller basis sets than with the traditional harmonic oscillator basis, and still benefit from the simple analytic properties of the DVR basis which requires no overlap integrals, simply permit using various Jacobi coordinates, and admit straightforward analyses of the UV and IR convergence properties.
