    "abstract": "The evolution of a two level system with a slowly varying Hamiltonian,\nmodeled as s spin 1/2 in a slowly varying magnetic field, and interacting with\na quantum environment, modeled as a bath of harmonic oscillators is analyzed\nusing a quantum Langevin approach. This allows to easily obtain the dissipation\ntime and the correction to the Berry phase in the case of an adiabatic cyclic\nevolution.",
