Simple Matrix Elements with Dynamical Fermions
The High Energy Monte Carlo Grand Challenge
We report on studies of simple matrix elements from simulations with two flavors of sea quarks, both staggered and Wilson. We show the decay constants of vector and pseudoscalar me…
Density matrix for a mesoscopic current ribbon
O. Heinonen, M. D. Johnson
We consider an ideal mesoscopic ribbon in which a steady azimuthal current is generated. We show that the closed interacting electron system in the presence of the current is descr…
Hadron Spectrum and Matrix Elements in QCD with Dynamical Wilson Fermions at 6/g^2=5.3
K. M. Bitar
We present results of a lattice simulation of quantum chromodynamics with two degenerate flavors of dynamic Wilson fermions at at each of two dynamical fermion hopping…
Addition Spectra of Quantum Dots in Strong Magnetic Fields
S. -R. Eric Yang, A. H. MacDonald, M. D. Johnson
We consider the magnetic field dependence of the chemical potential for parabolically confined quantum dots in a strong magnetic field. Approximate expressions based on the notion…
Three-Dimensional Quantum Gravity Coupled to Gauge Fields
Ray L. Renken, Simon M. Catterall, John B. Kogut
We show how to simulate U(1) gauge fields coupled to three-dimensional quantum gravity and then examine the phase diagram of this system. Quenched mean field theory suggests that a…
The XY Model on a Dynamical Random Lattice
S. Catterall, J. Kogut, R. Renken
We study the XY model on a lattice with fluctuating connectivity. The expectation is that at an appropriate critical point such a system corresponds to a compactified boson coupled…
