We suggest a model where the influence of an environment on the atom interference is associated with a random phase. The model
consists of sending a two-level state atom through two cavities, both containing a standing wave field in the Bragg regime
and Raman–Nath regime, respectively. In view of this model, we can visualize the loss of interference fringes if the randomness
of the phase increases, and the restoration of the pattern when it decreases, as which-path information. Then, the controllable
random noise acts as a decoherence that would destroy the quantum features. 相似文献

The present research work reports the study on crystal structure, vibrational spectroscopy and thermal analysis of organic-inorganic hybrid compound (C6H5(CH2)2NH3)2CdCl4. Single crystals of bis(phenethylammonium)tetrachlorocadmate (C6H5(CH2)2NH3)2CdCl4 (PEA–Cd) were obtained by diffusion at room temperature. This compound crystallizes in the orthorhombic space group C2cb with unit cell parameters a = 7.4444(2) Å, b = 38.8965(3) Å, c = 7.3737(2) Å and Z = 4. Single crystal structure has been solved and refined to R = 0.036 and wR = 0.092. The structure consists of an extended [CdCl4]2– network and two [C6H5(CH2)2NH3]+ cations to form a two-dimensional perovskite system. The infrared (IR) spectrum of the title compound was recorded at room temperature. Differential scanning calorimetry (DSC) was used to investigate the phase transition; this compound exhibits a reversible single solid-solid phase transition. 相似文献

High stereoselectivity was observed in the reactions of secondary alkylmagnesium compounds with bicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride and lactone 2 leading respectively to the formation of diastereomeric lactones and primary-secondary diols. 相似文献
