Bosonic string theory with constraints linear in the momenta
Merced Montesinos, Jose David Vergara
The Hamiltonian analysis of Polyakov action is reviewed putting emphasis in two topics: Dirac observables and gauge conditions. In the case of the closed string it is computed the…

Hamiltonian Solution of the Schwinger Model with Compact U(1)
Román Linares, Luis F. Urrutia, J. David Vergara
The complete exact solution of the Schwinger model with compact gauge group U(1), in the Hamiltonian approach, is presented . The compactification is imposed by demanding that the…

Matrix elements of the plaquette operator of Lattice Gauge Theory
G. Burgio, R. De Pietri, H. A. Morales-Tecotl +2
We show that in the spin-network basis it is possible to compute the matrix elements of any given operator of the Hamiltonian formulation of Lattice Gauge Theory (LGT). We give the…
