Finite-size effects on a lattice calculation
Rafael G. Campos, Eduardo S. Tututi
We study in this paper the finite-size effects of a non-periodic lattice on a lattice calculation. To this end we use a finite lattice equipped with a central difference derivative…
Lattice calculations on the spectrum of Dirac and Dirac-Kähler operators
R. G. Campos, J. L. Lopez-Lopez, R. Vera
We present a matrix technique to obtain the spectrum and the analytical index of some elliptic operators defined on compact Riemannian manifolds. The method uses matrix representat…
Aliasing modes in the lattice Schwinger model
Rafael G. Campos, Eduardo S. Tututi
We study the Schwinger model on a lattice consisting of zeros of the Hermite polynomials that incorporates a lattice derivative and a discrete Fourier transform with many propertie…
Ultralocality on the lattice
Rafael G. Campos, Eduardo S. Tututi
It is shown that the nonlocal Dirac operator yielded by a lattice model that preserves chiral symmetry and uniqueness of fields, approaches to an ultralocal and invariant under tra…
