The experimental results of the first- and second-order double-slit interference with such photorefractive fanning light source, cart be understood with the theoretical simulation in terms of Hanbury-Brown and Twiss effect.展开更多

Other experiments suggest a particle model of light. An experiment is performed with the Fraunhofer pattern from a first mask impinging on a transparent second mask with a slit. The screen pattern is an interference pattern such as produced in Young’s Experiment. An opaque strip between the first and second mask blocks the light of the center maxima from the first mask. The screen interference fringes remained. Moving the glass mask so the slit is removed from light shows the necessity of a slit in the second mask. This suggests a Newtonian type of light model. This experiment rejects the wave models of light.展开更多

Three optical wells separated averagely by -37 μm were created when illuminating by a YAG laser with power 1 mW. These wells with average trapping depth -0.5 μK and volume -74 μm^3 are suitable to trap and manipulate an atomic Bose-Einstein condensation （BEC）. Due to a controllable grating implemented by a spatial light modulator, an evolution between a triple-well trap and a single-well one is achievable by adjusting the height of potential barrier between adjacent wells. Based on this novel triple-well potentials, the loading and splitting of BEC, as well as the interference between three freely expanding BECs, are also numerically stimulated within the framework of mean-field treatment. By fitting three cosine functions with three Gaussian envelopes to interference fringe, the information of relative phases among three condensates is extracted.展开更多

The calculations are done for a vacuum-mode interferometer and then for a gas-mode interferometer. The calculations show that no light timing difference is detectable in a vacuum-mode interferometer, but once an optical medium is present in the light path down the arms of the interferometer, this is no longer the case and a timing difference is detectable. Further to this, the timing equations obtained from the analysis are used to model the historical experiments of Michelson-Morley and Miller (Mt Wilson) and predictions are made by the model that accurately match the actual recorded results from those experiments. Thus, this timing analysis confirms that there is a light speed anisotropy in a reference frame that is moving through space, indicating the presence of a preferred Aether reference frame through which the Earth is moving.展开更多
