Nuclear-size effects and a numerical approach to the Dirac equation
Bob Holdom, Roman Koniuk
Due to some current interest in this subject we have produced this note. There is no claim to anything new, except possibly to show that a direct numerical approach is quite simple…
A bound state model for a light scalar
Bob Holdom, Roman Koniuk
Recent lattice studies of near-conformal strong dynamics suggest the existence of a light scalar. This provides motivation to consider a simple Hamiltonian-based bound-state model…
Classical Simulation of Quantum Fields I
T. Hirayama, B. Holdom
We study classical field theories in a background field configuration where all modes of the theory are excited, matching the zero-point energy spectrum of quantum field theory. Ou…
Classical Simulation of Quantum Fields II
T. Hirayama, B. Holdom, R. Koniuk +1
We consider the classical time evolution of a real scalar field in 2 dimensional Minkowski space with a interaction. We compute the spatial and temporal two-point correlatio…
Less naive about supersymmetric lattice quantum mechanics
Joel Giedt, Roman Koniuk, Erich Poppitz +1
We explain why naive discretization results that have appeared in [hep-lat/0006013] do not appear to yield the desired continuum limit. The fermion propagator on the lattice inevit…
Unquenched Charmonium with NRQCD - Lattice 2000
Chris Stewart, Roman Koniuk
We present results from a series of NRQCD simulations of the charmonium system, both in the quenched approximation and with n_f = 2 dynamical quarks. The spectra show evidence for…
