Abstract:
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 thermal RPA namely renormalized thermal RPA and thermal second RPA are formulated.- finite temperature
- many-body problem
- Hamiltonian formalism
- operator: algebra
- phase space
