If applied to an Lz wavepacket which overlaps the interaction, it yields either scattering-type (improper) eigenstates or proper bound eigenstates. For negativ

In the method of quasireversibility (QR), ill-posed problems for linear partial differential equations are replaced by well-posed problems for equations of twice-higher order. In this paper, we consider two problems: the first for the backward heat equation, and the second for a nonparabolic evoluti

A new approach to density functional theory is presented. The ground state electronic density and energy of a many-electron system are obtained directly using a polynomial representation of the Heaviside step operator acting on a trial wavefunction. A radial coordinate extension of the distributed a
