We examin e the generation of bell state in bose - einstein condensates of two interacting species trapped in a double - well configuration analytically and the density of probability for finding the entangled bell state is given. we find that the oscillation amplitude of the probability of density for finding the entangled bell state becomes greater as the ratio of the interspecies interaction strength and the tunneling rate increases, moreover the self - interaction strength of the component a ( b ) has no effect on it. also we use the time - dependent su ( 2 ) gauge transformation to diagonalize the hamilton operator, obtain the berry phase and analytically the time - evolution operator
此外我們還研究了在雙阱玻色-愛因斯坦凝聚中糾纏態的演化，研究發現隨著組分間相互作用和隨穿率的比值的增加系統演化到bell態的概率變大，而且組分自身內在的相互作用對形成bell態的幾率沒有影響；並且用含時su （ 2 ）規范變換對角化哈密頓量得到了系統的berry位相和時間演化算符，並研究了量子隨穿過程。 -
It is the main purpose of this paper to calculate the energy splitting of ground state and excited states induced by thermally assisted quantum tunneling. first, a brief introduction is given for the theoretical and experimental studies on the magnetic macroscopic quantum effects. then, spin tunneling in a uniaxial ferromagnetic particle in transverse magnetic field is converted to a pseudoparticle moving in effective double - well potential with the help of the effective potential description of quantum spin systems developed by ulyanov and zaslavskii. finally using the periodic instanton method we evaluate the transition amplitude, energy shift and prefactor of wkb exponential and the energy splitting of ground state and the tunneling rate for excited states induced by thermally assisted quantum tunneling are obtained
文章首先對磁性宏觀量子效應的理論和實驗方面作了簡單介紹，然後藉助于ulyanov和zaslavskii發展的一種等效勢描述方法，把外磁場沿難磁化軸方向時的自旋隧穿約化成在等效雙勢阱中運動的粒子，利用瞬子方法給出基態能級劈裂，最後利用周期瞬子方法分別計算了隧穿幅、能級移動以及wkb前因子，從而給出由於熱助量子隧穿引起的激發態的隧穿率。 -
It shows that the bias in the post - irradiation recovery period and the ratio of the interface state to the electron tunneling influence the recovery rate
