    "abstract": "We show that bosonic fields may present anyonic behavior when interacting\nwith a fermion in a Jaynes-Cummings-like model. The proposal is accomplished\nvia the interaction of a two-level system with two quantized modes of a\nharmonic oscillator; under suitable conditions, the system acquires a\nfractional geometric phase. A crucial role is played by the entanglement of the\nsystem eigenstates, which provides a two-dimensional confinement in the\neffective evolution of the system, leading to the anyonic behavior. For a\nparticular choice of parameters, we show that it is possible to transmute the\nstatistics of the system continually from fermions to bosons. We also present\nan experimental proposal, in an ion-trap setup, in which fractional statistical\nfeatures can be generated, controlled, and measured.",
