Effective Hamiltonian with holomorphic variables
A. Cuccoli, V. Tognetti, R. Giachetti +2
The pure-quantum self-consistent harmonic approximation (PQSCHA) permits to study a quantum system by means of an effective classical Hamiltonian - depending on quantum coupling an…

Effective Potential and Quantum Dynamical Correlators
R. Giachetti, R. Maciocco, V. Tognetti
The approach to the calculation of quantum dynamical correlation functions is presented in the framework of the Mori theory. An unified treatment of classic and quantum dynamics is…

Unitarity of induced representations from coisotropic quantum groups
F. Bonechi, N. Ciccoli, R. Giachetti +2
We study unitarity of the induced representations from coisotropic quantum subgroups which were introduced in math.QA/9804138. We define a real structure on coisotropic subgroups w…
