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
Wedding Anniversary Wedding Anniversary Wedding Anniversary is an Indian Hindi-language romantic drama film, directed by Shekhar S Jha, produced by Kumar V Mahant and Achut Naik, and presented by Bharat Shah. The film stars Nana Patekar and Mahie Gill in leading roles and was released on 24 February 2017.
