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
Telugu wedding ceremony The ceremony is held under a "Kaḷyāṇa Maṇḍapaṃ" or wedding pavilion decorated with fresh flowers. The "Nādasvaram" (also called the "Shehnai" in North India) is an Indian musical instrument that traditionally accompanies most Telugu weddings. Each element in the ceremony is connected and is given special importance. Historically, the groom would ride an elephant to the bride's home where the wedding is supposed to take place. This practice is called "Gajaarohana". Today this tradition is declining. Some marriage ceremonies are held in a temple in the presence of god, but most are conducted outside because of the number of people
