Isoscalar monopole excitations in O: -cluster states at low energy and mean-field-type states at higher energy
T. Yamada, Y. Funaki, T. Myo +5
Isoscalar monopole strength function in O up to MeV is discussed. We found that the fine structures at the low energy region up to MeV in t…
Spin degrees of freedom and flattening of the spectra of single-particle excitations in strongly correlated Fermi systems
V. A. Khodel, P. Schuck, M. V. Zverev
The impact of long-range spin-spin correlations on the structure of a flat portion in single-particle spectra , which emerges beyond the point, where the Landau state loses i…
Pair Fluctuations in Ultra-small Fermi Systems within Self-Consistent RPA at Finite Temperature
A. Storozhenko, P. Schuck, J. Dukelsky +2
A self-consistent version of the Thermal Random Phase Approximation (TSCRPA) is developed within the Matsubara Green's Function (GF) formalism. The TSCRPA is applied to the many le…
Few-Body States in Fermi-Systems and Condensation Phenomena
P. Schuck, M. Beyer, G. Roepke +2
Residual interactions in many particle systems lead to strong correlations. A multitude of spectacular phenomenae in many particle systems are connected to correlation effects in s…
The Linear Sigma-Model in the 1/N-Expansion via Dynamical Boson Mappings and Applications to -Scattering
Z. Aouissat, P. Schuck, J. Wambach
We present a non-perturbative method for the study of the O(N+1)-version of the linear sigma-model. Using boson-mapping techniques, in close analogy to those well-known for fermion…
Pion-pair formation and the pion dispersion relation in a hot pion gas
T. Alm, G. Chanfray, P. Schuck +1
The possibility of pion--pair formation in a hot pion gas, based on the bosonic gap equation, is pointed out and discussed in detail. The critical temperature for condensation of p…
