A polynomial Ansatz for norm-conserving pseudopotentials
A polynomial Ansatz for norm-conserving pseudopotentials is a scholarly work by Martin Kiffner and Davide Ceresoli, published in 2018 in ''Journal of Physics: Condensed Matter''. The main subjects of the publication include mathematical analysis, norm, degree, cutoff, polynomial, quantum mechanics, density functional theory, pseudopotential, mathematics, Ansatz, physics, Non-Hermitian quantum mechanics, and electronic structure. The authors show that efficient norm-conserving pseudopotentials for electronic structure calculations can be obtained from a polynomial Ansatz for the potential.
