Separable Expansions of V_{low} for 2- and 3-Nucleon Systems
J. R. Shepard, J. A. McNeil
We present an alternative organizational scheme for developing effective theories of 2- and 3-body systems that is systematic, accurate, and efficient with controlled errors. To il…
Convergence of 2-Body Effective Range Expansions for Quartet Scattering
J. R. Shepard, J. A. McNeil
We examine the convergence properties of the 2-nucleon Effective Range Expansion as used in Effective Theories (ET-ERE's) for 3-nucleon calculations. We accomplish this by accounti…
Scaling functions applied to three-body recombination of Cesium-133 atoms
L. Platter, J. R. Shepard
We demonstrate the implications of Efimov physics in the recently measured recombination rate of Cesium-133 atoms. By employing previously calculated results for the energy depende…
Three Bosons in One Dimension with Short Range Interactions I: Zero Range Potentials
Nirav P. Mehta, James R. Shepard
We consider the three-boson problem with -function interactions in one spatial dimension. Three different approaches are used to calculate the phase shifts, which we interpret i…
Low-energy operators in effective theories
N. P. Mehta, C. Felline, J. R. Shepard +1
Modern effective-theory techniques are applied to the nuclear many-body problem. A novel approach is proposed for the renormalization of operators in a manner consistent with the c…
Novel Methods for Determining Effective Interactions for the Nuclear Shell Model
H. Mueller, J. R. Shepard, J. Piekarewicz
The Contractor Renormalization (CORE) method is applied in combination with modern effective-theory techniques to the nuclear many-body problem. A one-dimensional--yet ``realistic'…
