A quantum model for collective recoil lasing
R. Bonifacio, M. M. Cola, N. Piovella
Free Electron Laser (FEL) and Collective Atomic Recoil Laser (CARL) are described by the same model of classical equations for properly defined scaled variables. These equations ar…
Selfsynchronization and dissipation-induced threshold in collective atomic recoil lasing
C. von Cube, S. Slama, D. Kruse +5
Networks of globally coupled oscillators exhibit phase transitions from incoherent to coherent states. Atoms interacting with the counterpropagating modes of a unidirectionally pum…
Collective Atomic Recoil Lasing Including Friction and Diffusion Effects
G. R. M. Robb, N. Piovella, A. Ferraro +3
We extend the Collective Atomic Recoil Lasing (CARL) model including the effects of friction and diffusion forces acting on the atoms due to the presence of optical molasses fields…
Quantum state engineering assisted by entanglement
Matteo G. A. Paris, Mary Cola, Rodolfo Bonifacio
We suggest a general scheme for quantum state engineering based on conditional measurements carried out on entangled twin-beam of radiation. Realistic detection schemes such as {\s…
Time as a statistical variable and intrinsic decoherence
Rodolfo Bonifacio
We propose a novel approach to intrinsic decoherence without adding new assumptions to standard quantum mechanics. We generalize the Liouville equation just by requiring the dynami…
