Tensor Reduction for Feynman Integrals with Lorentz and Spinor Indices
Jae Goode, Franz Herzog, Anthony Kennedy +2
We present an efficient graphical approach to construct projectors for the tensor reduction of multi-loop Feynman integrals with both Lorentz and spinor indices in dimensions.…
Renormalizability of the Schrödinger Functional
A. D. Kennedy, Stefan Sint
Symanzik showed that quantum field theory can be formulated on a space with boundaries by including suitable surface interactions in the action to implement boundary conditions. We…
Numerical determination of partial spectrum of Hermitian matrices using a Lanczos method with selective reorthogonalization
Chris Johnson, A. D. Kennedy
We introduce a new algorithm for finding the eigenvalues and eigenvectors of Hermitian matrices within a specified region, based upon the LANSO algorithm of Parlett and Scott. It u…
Shadow Hamiltonians, Poisson Brackets, and Gauge Theories
A. D. Kennedy, P. J. Silva, M. A. Clark
Numerical lattice gauge theory computations to generate gauge field configurations including the effects of dynamical fermions are usually carried out using algorithms that require…
Monte Carlo Integration with Subtraction
Rudy Arthur, A. D. Kennedy
This paper investigates a class of algorithms for numerical integration of a function in d dimensions over a compact domain by Monte Carlo methods. We construct a histogram approxi…
Bounds on the convergence of Ritz values from Krylov subspaces to interior eigenvalues of Hermitean matrices
Chris Johnson, A. D. Kennedy
We consider bounds on the convergence of Ritz values from a sequence of Krylov subspaces to interior eigenvalues of Hermitean matrices. These bounds are useful in regions of low sp…
