Effective operators within the ab initio no-core shell model
Ionel Stetcu, Bruce R. Barrett, Petr Navratil +1
We implement an effective operator formalism for general one- and two-body operators, obtaining results consistent with the no-core shell model (NCSM) wave functions. The Argonne V…
Ab-initio No-Core Shell Model With Many-Body Forces
M. S. Fayache, J. P. Vary, B. R. Barrett +2
Working in the framework of the ab-initio no-core shell model, we derive two-body effective interactions microscopically for specific harmonic-oscillator basis spaces from the real…
The Challenge of Light-Front Quantisation: Recent Results
Victor T. Kim, Victor A. Matveev, Grigorii B. Pivovarov +1
We explain what is the challenge of light-front quantisation, and how we can now answer it because of recent progress in solving the problem of zero modes in the case of non-Abelia…
On Mathematical Structure of Effective Observables
C. P. Viazminsky, James P. Vary
We decompose the Hilbert space of wave functions into two subspaces, and assign to a given observable two effective representatives that act in the model space. The first serves to…
Massive Schwinger Model for Small Fermion Mass
J. P. Vary, T. J. Fields, H. J. Pirner
We examine QED (the massive Schwinger model) to extend existing perturbation results in , and compare our results with lattice and DLCQ calculations. (Based on a t…
