Berry phase in open quantum systems: a quantum Langevin equation approach
Gabriele De Chiara, Artur Lozinski, G. Massimo Palma
The evolution of a two level system with a slowly varying Hamiltonian, modeled as s spin 1/2 in a slowly varying magnetic field, and interacting with a quantum environment, modeled…

Berry phase for a spin 1/2 in a classical fluctuating field
Gabriele De Chiara, G. Massimo Palma
The effect of fluctuations in the classical control parameters on the Berry phase of a spin 1/2 interacting with a adiabatically cyclically varying magnetic field is analyzed. It i…
