Abstract: Antisymmetric interactions with respect to spin direction give rise to spin rotations in certain perfect crystals. A new perfect crystal technique, termed Dual-Polarised-Beam technique (DPB), can be used to boost the sensitivity of the spin rotation measurements by several orders of magnitude. The typical Zeeman splitting is shown and a future experiment of neutron EDM detection with DPB using new crystals is also discussed.
