http://dbpedia.org/ontology/abstract In physics, Hamiltonian lattice gauge theoIn physics, Hamiltonian lattice gauge theory is a calculational approach to gauge theory and a special case of lattice gauge theory in which the space is discretized but time is not. The Hamiltonian is then re-expressed as a function of degrees of freedom defined on a d-dimensional lattice. Following Wilson, the spatial components of the vector potential are replaced with Wilson lines over the edges, but the time component is associated with the vertices. However, the temporal gauge is often employed, setting the electric potential to zero. The eigenvalues of the Wilson line operators U(e) (where e is the (oriented) edge in question) take on values on the Lie group G. It is assumed that G is compact, otherwise we run into many problems. The conjugate operator to U(e) is the electric field E(e) whose eigenvalues take on values in the Lie algebra . The Hamiltonian receives contributions coming from the plaquettes (the magnetic contribution) and contributions coming from the edges (the electric contribution). Hamiltonian lattice gauge theory is exactly dual to a theory of spin networks. This involves using the Peter–Weyl theorem. In the spin network basis, the spin network states are eigenstates of the operator .k states are eigenstates of the operator . , Em física, teoria de retículo gauge hamiltEm física, teoria de retículo gauge hamiltoniano é uma aproximação matemática a teoria de gauge e um caso especial da teoria do retículo gauge no qual o espaço é discreto mas o tempo não. O Hamiltoniano é então re-expresso como uma função de graus de liberdade definidos sobre um retículo d-dimensional. Segundo Wilson, os componentes espaciais do vetor potencial são substituídos com linhas de Wilson sobre os grafos, mas o componente tempo é associado com os vértices. Contudo, o gauge temporal é frequentemente empregado, levando o potencial elétrico a zero. Os autovalores dos operadores linha de Wilson U(e) (onde e é o grafo (orientado) em questão) tomado sobre valores sobre o grupo de Lie G. Assume-se que G é compacto ou caso contrário, tem-se muitos problemas. O operador conjugado a U(e) é o campo elétrico E(e) cujos autovalores assumem valores na álgebra de Lie . O Hamiltoniano recebe contribuições vindas das plaquetas (a contribuição magnética) e contribuições vindas dos grafos (a contribuição elétrica). A teoria de retículo gauge hamiltoniano é exatamente dupla a uma teoria de redes de spin. Isto envolve a utilização do teorema de Peter-Weyl. Na base da rede de spin, os estados da rede de spin são autovalores do operador .rede de spin são autovalores do operador .
