Reply to Cohen's comment on the rotation--vibration coupling in chiral soliton models
H. Walliser, H. Weigel
In this short note we summarize the main results of our paper [hep-ph/0510055] and reply to a recent comment [hep-ph/0511174] on that paper.
Bound State versus Collective Coordinate Approaches in Chiral Soliton Models and the Width of the Pentaquark
H. Walliser, H. Weigel
We thoroughly compare the bound state and rigid rotator approaches to three--flavored chiral solitons. We establish that these two approaches yield identical results for the baryon…
Exotic baryon states in topological soliton models
H. Walliser, V. B. Kopeliovich
The novel observation of an exotic strangeness S=+1 baryon state at 1.54 GeV will trigger an intensified search for this and other baryons with exotic quantum numbers. This state w…
Comment on "Reverse Brazil Nut Problem: Competition between Percolation and Condensation"
H. Walliser
In a recent paper [Phys. Rev. Lett. 86, 3423 (2001)] D.C. Hong, P.V. Quinn and S. Luding investigated the Brazil nut problem and the reverse Brazil nut problem at fixed temperature…
Effective action for quantum Hall skyrmions
A. Teufel, H. Walliser
Recently, an O(3) type of effective action was proposed for the quantum Hall ferromagnet, which accounts for bag formation observed in microscopic Hartree- Fock calculations. We ap…
Bag Formation in Quantum Hall Ferromagnets
Hans Walliser
Charged skyrmions or spin-textures in the quantum Hall ferromagnet at filling factor nu=1 are reinvestigated using the Hartree-Fock method in the lowest Landau level approximation.…
