    "abstract": "We analyse the geometric phase due to the Stark shift in a system composed of\na bosonic field, driven by time-dependent linear amplification, interacting\ndispersively with a two-level (fermionic) system. We show that a geometric\nphase factor in the joint state of the system, which depends on the fermionic\nstate (resulting form the Stark shift), is introduced by the amplification\nprocess. A clear geometrical interpretation of this phenomenon is provided. We\nalso show how to measure this effect in an interferometric experiment and to\ngenerate geometric \"Schrodinger cat\"-like states. Finally, considering the\ncurrently available technology, we discuss a feasible scheme to control and\nmeasure such geometric phases in the context of cavity quantum electrodynamics.",
