51Squashed entanglement — Squashed entanglement, also called CMI entanglement (CMI can be pronounced see me ), is an information theoretic measure of quantum entanglement for a bipartite quantum system. If varrho {A, B} is the density matrix of a system (A,B) composed of… …
52Observer (special relativity) — The term observer in special relativity refers most commonly to an inertial reference frame. Less often it may refer to an arbitrary non inertial reference frame; in particular, a Rindler frame is sometimes called an accelerating observer . In… …

54Wannier function — The Wannier functions are a complete set of orthogonal functions used in solid state physics. They were introduced by Gregory Wannier. [http://dx.doi.org/10.1103/PhysRev.52.191 The structure of electronic excitation levels in insulating crystals …
55Dimension — 0d redirects here. For 0D, see 0d (disambiguation). For other uses, see Dimension (disambiguation). From left to right, the square, the cube, and the tesseract. The square is bounded by 1 dimensional lines, the cube by 2 dimensional areas, and… …
56Kernel (matrix) — In linear algebra, the kernel or null space (also nullspace) of a matrix A is the set of all vectors x for which Ax = 0. The kernel of a matrix with n columns is a linear subspace of n dimensional Euclidean space.[1] The dimension… …
57Least squares — The method of least squares is a standard approach to the approximate solution of overdetermined systems, i.e., sets of equations in which there are more equations than unknowns. Least squares means that the overall solution minimizes the sum of… …
58Hankel matrix — In linear algebra, a Hankel matrix, named after Hermann Hankel, is a square matrix with constant (positive sloping) skew diagonals, e.g.::egin{bmatrix}a b c d e b c d e f c d e f g d e f g h e f g h i end{bmatrix}.In mathematical terms::a {i,j} …

60Crystallographic restriction theorem — The crystallographic restriction theorem in its basic form was based on the observation that the rotational symmetries of a crystal are usually limited to 2 fold, 3 fold, 4 fold, and 6 fold. However, quasicrystals can occur with other symmetries …
