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. In this work the PQSCHA is reform…

Effective Hamiltonian, Mori Product and Quantum Dynamics
A. Cuccoli, V. Tognetti, R. Giachetti +1
An appropriate extension of the effective potential theory is presented that permits the approximate calculation of the dynamical correlation functions for quantum systems. These a…

QUANTIZATION OF A CLASS OF PIECEWISE AFFINE TRANSFORMATIONS ON THE TORUS
S. De Bievre, M. Degli Esposti, R. Giachetti
We present a unified framework for the quantization of a family of discrete dynamical systems of varying degrees of "chaoticity". The systems to be quantized are piecewise affine m…
