Muffin-tin approximation Muffin-tin approximation The muffin-tin approximation is a shape approximation of the potential well in an crystal lattice. It is most commonly employed in quantum mechanical simulations of the electronic band structure in solids. The approximation was proposed by John C. Slater. Augmented plane wave method (APW) is a method which uses muffin-tin approximation. It is a method to approximate the energy states of an electron in a crystal lattice. The basic approximation lies in the potential in which the potential is assumed to be spherically symmetric in the muffin-tin region and constant in the interstitial region. Wave functions (the augmented
The Weight Is a Gift that I had in mind was that your legs would just grow down to the bottom and you’d walk out. We are capable of rescuing ourselves. I was holding onto that thought or being hopeful about it, since I was going through a hard time in a relationship." All tracks written by Matthew Caws, Daniel Lorca and Ira Elliot, except where noted. Many albums included a four-track bonus disc. The Weight Is a Gift The Weight Is a Gift is the fourth album by the alternative rock band, Nada Surf. It was released on Barsuk in 2005. The album was
