A primitive cell is a unit cell that contains exactly one lattice point. For unit cells generally, lattice points that are shared by n cells are counted as 1 / n of the lattice points contained in each of those cells; so for example a primitive unit cell in three dimensions which has lattice points only at its eight vertices is considered to contain 1 / 8 of each of them.

Lattice Miner [1] is a formal concept analysis software tool for the construction, visualization and manipulation of concept lattices.It allows the generation of formal concepts and association rules as well as the transformation of formal contexts via apposition, subposition, reduction and object/attribute generalization, and the manipulation of concept lattices via approximation, projection ...
The seven lattice systems and their Bravais lattices in three dimensions. In geometry and crystallography, a Bravais lattice, named after Auguste Bravais (), [1] is an infinite array of discrete points generated by a set of discrete translation operations described in three dimensional space by
The diamond lattice can be viewed as a pair of intersecting face-centered cubic lattices, with each separated by 1 / 4 of the width of the unit cell in each dimension. Many compound semiconductors such as gallium arsenide , β- silicon carbide , and indium antimonide adopt the analogous zincblende structure , where each atom has nearest ...
When talking about solid materials, the discussion is mainly around crystals – periodic lattices. Here we will discuss a 1D lattice of positive ions. Assuming the spacing between two ions is a, the potential in the lattice will look something like this: The mathematical representation of the potential is a periodic function with a period a.
If the lattice is even, the form has level 1, and if the lattice is odd the form has Γ 0 (4) structure (i.e., it is a modular form of level 4). Due to the dimension bound on spaces of modular forms, the minimum norm of a nonzero vector of an even unimodular lattice is no greater than ⎣ n /24⎦ + 1.
Tips For Making The Best Christmas Morning Breakfast. Keep pancakes warm in the oven if cooking for a crowd.Place pancakes on a baking sheet, on a wire rack, at around 200F in the oven until you ...
Short integer solution (SIS) and ring-SIS problems are two average-case problems that are used in lattice-based cryptography constructions. Lattice-based cryptography began in 1996 from a seminal work by Miklós Ajtai [1] who presented a family of one-way functions based on SIS problem.
