Non-perturbative Methods in Modal Field Theory
Nathan Salwen
Several issues in the modal approach to quantum field theory are discussed. Within the formalism of spherical field theory, differential renormalization is presented and shown to r…
Lower energy bounds for quantum lattice Hamiltonians
Dean Lee, Nathan Salwen
We derive general lower energy bounds for the ground state energy of any translationally invariant quantum lattice Hamiltonian. The bounds are given by the ground state energy of r…
Still Baking
Nathan Salwen, Ron Rubin
We present here a simple proof of the non-existence of a non-periodic invariant point for the quantum baker's map propagator presented in Rubin and Salwen (Annals of Physics, 1998)…
A Parity-Conserving Canonical Quantization for the Baker's Map
Ron Rubin, Nathan Salwen
We present here a complete description of the quantization of the baker's map. The method we use is quite different from that used in Balazs and Voros [BV] and Saraceno [S]. We use…
