Automated computation of spin- and colour-correlated Born matrix elements
نویسنده
چکیده
I report on an implementation of an algorithm for the automated numerical calculation of spinand colour-correlated Born matrix elements in QCD. These spinand colour-correlated matrix elements are needed for NLO calculations in combination with the subtraction method. Both massless and massive quarks are considered. There are no restrictions on the number of external particles. As a trivial sub-case, the algorithm also applies to Born matrix elements without any correlations. These are sufficient for leading order calculations.

“Easy spin-symmetry-adaptation.” Exploitation of the Clifford algebra unitary group in correlated many-electron theories
An efficient scheme for the generation of spin-symmetry adapted matrix elements required by all correlated many electron wave function methods of electronic structure theory is briefly outlined. Matrix elements can be formulated in the Clifford algebra unitary group representation of Gel’fand-Tsetlin basis, Clifford-Weyl basis, Jeziorski-Paldus-Jankowski basis or determinant basis in order to e...
متن کاملMulti-distributed entanglement in finitely correlated chains
– The entanglement-sharing properties of an infinite spin-chain are studied when the state of the chain is a pure, translation-invariant state with a matrix-product structure [1]. We study the entanglement properties of such states by means of their finitely correlated structure [2]. These states are recursively constructed by means of an auxiliary density matrix ρ on a matrix algebra B and a c...
متن کاملMatrix Elements of Thiemann’s Hamiltonian Constraint in Loop Quantum Gravity
We present an explicit computation of matrix elements of the hamiltonian constraint operator in non-perturbative quantum gravity. In particular, we consider the euclidean term of Thiemann’s version of the constraint and compute its action on trivalent states, for all its natural orderings. The calculation is performed using graphical techniques from the recoupling theory of colored knots and li...

Curls and curves of a shell interweave its various strain modes and link them together. This interactional behavior has yet frustrated all attempts for the construction of shell templates, which needs for an individual element test in traditional approaches. Such a test fails to work for shell elements and must be reconstructed. In this paper, it is tried to study shell interactional behavior a...
متن کاملAccurate ab Initio Spin Densities
We present an approach for the calculation of spin density distributions for molecules that require very large active spaces for a qualitatively correct description of their electronic structure. Our approach is based on the density-matrix renormalization group (DMRG) algorithm to calculate the spin density matrix elements as a basic quantity for the spatially resolved spin density distribution...
