    "abstract": "We study the effect of a phase shift on the amount of transferrable two-spin\nentanglement in a spin chain. We consider a ferromagnetic Heisenberg/XY spin\nchain, both numerically and analytically, and two mechanisms to generate a\nphase shift, the Aharonov-Casher effect and the Dzyaloshinskii-Moriya\ninteraction. In both cases, the maximum attainable entanglement is shown to be\nsignificantly enhanced, suggesting its potential usefulness in quantum\ninformation processing.",
