Wannier Functions in a Simple Nonperiodic System
Wannier Functions in a Simple Nonperiodic System is a scholarly work, published in 1973 in ''Physical Review B''. The main subjects of the publication include simple, wave function, mathematical analysis, physics, mathematical physics, exponential function, eigenfunction, Wannier function, quantum mechanics, density functional theory, computational chemistry, lattice, theoretical physics, and electronic band structure. The paper defines and analyzes in detail the Wannier functions ${a}_{l}$ of a one-dimensional periodic lattice with a point defect.
