WebBirefringence Measurement. Birefringence is a difference in refractive index that occurs along different axes in a material. In crystals like calcite this is an intrinsic effect resulting from the atomic structure. The result is that light travelling along one axis experiences a different refractive index than light travelling along a different ... WebA new method to amplify the photon-axion conversions in magnetic field is proposed using a buffer gas at a specific pressure. As a first result, new bounds for mass and coupling constant for purely laboratory experiments aiming to detect any hypothetical scalars and pseudo-scalars which can couple to photons were obtained at 95% confidence level, …
