    "abstract": "We calculate the Berry phase of a spin-1/2 particle in a magnetic field\nconsidering the quantum nature of the field. The phase reduces to the standard\nBerry phase in the semiclassical limit and eigenstate of the particle acquires\na phase in the vacuum. We also show how to generate a vacuum induced Berry\nphase considering two quantized modes of the field which has a interesting\nphysical interpretation.",
