    "abstract": "We exhibit a specific implementation of the creation of geometrical phase\nthrough the state-space evolution generated by the dynamic quantum Zeno effect.\nThat is, a system is guided through a closed loop in Hilbert space by means a\nsequence of closely spaced projections leading to a phase difference with\nrespect to the original state. Our goal is the proposal of a specific\nexperimental setup in which this phase could be created and observed. To this\nend we study the case of neutron spin, examine the practical aspects of\nrealizing the \"projections,\" and estimate the difference between the idealized\nprojections and the experimental implementation.",
