Lattice energy-momentum tensor with Symanzik improved actions.
We deene the energy-momentum tensor on lattice for the 4 and for the nonlinear-model Symanzik tree-improved actions, using Ward identities or an explicit matching procedure. The resulting operators give the correct one loop scale anomaly, and in the case of the sigma model they can have applications in Monte Carlo simulations .
متن کاملImproved lattice actions
The idea to improve lattice actions [1,2] is nearly as old as the use of lattices in regularizing field theories [3]. Nevertheless, until recently numerical simulations were performed mostly with the simplest (standard) form of lattice actions. This attitude seems to have been altered — at this conference there were probably more contributions using some kind of improved action than the standar...
متن کاملEnergy-Momentum tensor on foliations
In this paper, we give a new lower bound for the eigenvalues of the Dirac operator on a compact spin manifold. This estimate is motivated by the fact that in its limiting case a skew-symmetric tensor (see Equation (1.6)) appears that can be identified geometrically with the O’Neill tensor of a Riemannian flow, carrying a transversal parallel spinor. The Heisenberg group which is a fibration ove...
متن کاملGlueballs from Improved Lattice Actions
Glueballs and hybrid mesons are presently of great interest theoretically and experimentally. The lattice formulation of QCD provides an ideal setting in which to carry out theoretical studies of such systems from first principles using sophisticated numerical simulations. In order to extract the physical properties of glueballs and hybrid mesons from such simulations, systematic errors from th...
متن کاملThe Energy-Momentum Tensor for Cosmological Perturbations
We study the effective energy-momentum tensor (EMT) for cosmological perturbations and formulate the gravitational back-reaction problem in a gauge invariant manner. We analyze the explicit expressions for the EMT in the cases of scalar metric fluctuations and of gravitational waves and derive the resulting equations of state. The formalism is applied to investigate the back-reaction effects in...
