WitrynaAn ITensor is a tensor whose interface is independent of its memory layout. ITensor indices are objects which carry extra information and which 'recognize' each other (compare equal to each other). The ITensor library also includes composable and extensible algorithms for optimizing and transforming tensor networks, such as matrix … WitrynaFor instance, in 3 dimensions the Ising model is dual to an Ising gauge model. Intuitive idea. The 2-dimensional Ising model exists on a lattice, which is a collection of squares in a chessboard pattern. With the finite lattice, the edges can be connected to form a torus. ...
