Barrier penetration in 1+1-dimensional O(n) sigma models
E. Moreno, P. Orland
The O(n) nonlinear sigma model in 1+1 dimensions is examined as quantum mechanics on an infinite-dimensional configuration space. Two metrics are defined in this space. One of thes…
On the Renormalization of Hamiltonians
G. Alexanian, E. F. Moreno
We introduce a novel method for the renormalization of the Hamiltonian operator in Quantum Field Theory in the spirit of the Wilson renormalization group. By a series of unitary tr…
Renormalization of the Hamiltonian and a geometric interpretation of asymptotic freedom
G. Alexanian, E. F. Moreno
Using a novel approach to renormalization in the Hamiltonian formalism, we study the connection between asymptotic freedom and the renormalization group flow of the configuration s…
Quasiparticle operators with non-Abelian braiding statistics
Daniel C. Cabra, Enrique F. Moreno, Gerardo L. Rossini
We study the gauge invariant fermions in the fermion coset representation of Wess-Zumino-Witten models which create, by construction, the physical excitations (quasiparti…
Electrically Charged Vortex Solution in Born-Infeld Theory
E. Moreno, C. Nuñez, F. A. Schaposnik
We obtain electrically charged vortex solutions for the Born-Infeld Higgs system with a Chern Simons term. We analyse numerically these solutions, comparing their properties with t…
