Lipkin-Meshkov-Glick model at finite temperature
A. N. Storozhenko, D. S. Kosov, A. I. Vdovin
The Lipkin-Meshkov-Glick model is used to examine the validity of some approximate methods in a many-body theory at finite temperatures. Namely, the thermal random phase approximat…

Nuclear Many-Body Problem at Finite Temperature: A TFD Approach
D. S. Kosov, A. I. Vdovin, J. Wambach
Based on the formalism of thermo-field dynamics a new approach for studying collective excitations in hot finite Fermi systems is presented. Two approximations going beyond the the…

Treatment of baryonic resonances in the RQMD approach including scalar-vector mean fields
C. Fuchs, L. Sehn, Amand Faessler +3
In the relativistic Quantum Molecular Dynamics (RQMD) approach baryons are described within the framework of covariant hamilton constraint dynamics. The inclusion of a relativistic…
