Two-Dimensional Electron Gas with Cold Atoms in Non-Abelian Gauge Potentials
Indubala I. Satija, Daniel C. Dakin, J. Y. Vaishnav +1
Motivated by the possibility of creating non-Abelian fields using cold atoms in optical lattices, we explore the richness and complexity of non-interacting two-dimensional electron…
Metal-Insulator Transition Revisited for Cold Atoms in Non-Abelian Gauge Potentials
Indubala I. Satija, Daniel C. Dakin, Charles W. Clark
We discuss the possibility of realizing metal-insulator transitions with ultracold atoms in two-dimensional optical lattices in the presence of artificial gauge potentials. Such tr…
Pion Photoproduction Amplitude Relations in the 1/N_c Expansion
Thomas D. Cohen, Daniel C. Dakin, Richard F. Lebed +1
We derive expressions for pion photoproduction amplitudes in the 1/N_c expansion of QCD, and obtain linear relations directly from this expansion that relate electromagnetic multip…
Pion-Nucleon Scattering Relations at Next-to-Leading Order in 1/N_c
Thomas D. Cohen, Daniel C. Dakin, Richard F. Lebed +1
We obtain relations between partial-wave amplitudes for pi-N-->pi-N and pi-N-->pi-Delta directly from large N_c QCD. While linear relations among certain amplitudes holding at lead…
Excited Baryon Decay Widths in Large N_c QCD
Thomas D. Cohen, Daniel C. Dakin, Richard F. Lebed +1
We study excited baryon decay widths in large N_c QCD. It was suggested previously that some spin-flavor mixed-symmetric baryon states have strong couplings of O(N_c^{-1/2}) to nuc…
Nucleon-Nucleon Scattering under Spin-Isospin Reversal in Large-N_c QCD
Thomas D. Cohen, Daniel C. Dakin
The spin-flavor structure of certain nucleon-nucleon scattering observables derived from the large N_c limit of QCD in the kinematical regime where time-dependent mean-field theory…
