Baryon Spectrum and Chiral Dynamics
L. Ya. Glozman
New results on baryon structure and spectrum developed in collaboration with Dan Riska [1-4] are reported. The main idea is that beyond the chiral symmetry spontaneous breaking sca…
Lattice Schwinger Model with interpolated Gauge Fields
Christof Gattringer
We analyze the Schwinger model on an infinite lattice using the continuum definition of the fermion determinant and a linear interpolation of the lattice gauge fields. The possible…
Force calculation and atomic-structure optimization for the full-potential linearized augmented plane-wave code WIEN
Bernd Kohler, Steffen Wilke, Matthias Scheffler +2
Following the approach of Yu, Singh, and Krakauer [Phys. Rev. B 43 (1991) 6411] we extended the linearized augmented plane wave code WIEN of Blaha, Schwarz, and coworkers by the ev…
Spin and Gauge Systems on Spherical Lattices
Ch. Hoelbling, A. Jakovac, J. Jersak +2
We present results for 2D and 4D systems on lattices with topology homotopic to the surface of a (hyper) sphere or . Finite size scaling is studied in situations with ph…
The Charm and Bottom Hyperons in a Chiral Quark Model
L. Ya. Glozman, D. O. Riska
The spectrum of the C=1 hyperons is well described by the constituent quark model, if the fine structure interaction between the light and strange quarks is mediated by the $SU(3)_…
Quark Model Explanation of the Branching Ratios
L. Ya. Glozman, D. O. Riska
The constituent quark model can explain the strong selectivity of the decay branching ratios of the nucleon resonances if the fine structure interaction between the constituen…
