Gauge Invariance and Confinement in Noncompact Simulations of SU(2)
Kevin Cahill
Wilson loops have been measured at strong coupling, , on a lattice in a noncompact simulation of pure SU(2) in which random compact gauge transformations impose a kin…
Hypersensitivity to Perturbations in the Quantum Baker's Map
R. Schack, C. M. Caves
We analyze a randomly perturbed quantum version of the baker's transformation, a prototype of an area-conserving chaotic map. By numerically simulating the perturbed evolution, we…
The length of a typical Huffman codeword
R. Schack
If p is the probability of a letter of a memoryless source, the length l of the corresponding binary Huffman codeword can be very different from the value -log p. We show that, nev…
A More-Effective Potential
Kevin Cahill
In theories with spontaneous symmetry breaking, the loop expansion of the effective potential is awkward. In such theories, the exact effective potential is real and con…
