矩形勢阱 的英文怎麼說
中文拼音 [jǔxíngshìjǐng]
矩形勢阱
英文
rectangular potential well-
The effect of an applied electric field on the binding energy of shallow donor impurities in rectangular cross section gaas qwws was presented by montes et al, by considering an infinite confinement potential and using a variational scheme
外加電場對矩形量子阱線中淺施主雜質束縛能的效應是由montes等人提出的，他們採用變分法討論了無限深勢阱的量子線結構。From the exact expression of the field, we obtain a multipole polynomial expansion, and under the paraxial condition we furthermore obtain the approximate expression. the loffe trap, consisting of two coils with parallel currents and four straight conductors with currents in alternating directions, is one of the most important traps. we specially study the field structure of it by using both the exact expression and a multipole polynomial expansion that facilitates studies of classical or quantum orbits. if the region near the origin is of interest, we may obtain a simple expression of the field and this configuration may be called idealized loffe trap
若只討論阱中的近原點區域時，阱中的磁場可以呈現出一種簡潔的形式，人們把它稱為理想ioffe阱。磁矩反平行於磁場的中性粒子在阱中與磁場發生相互作用，藉助相互作用勢，可以獲得粒子在阱中的經典運動方程。在一定的近似條件下，我們可以採用逐次近似的方法，使方程簡化，其中三個分量式中關于z的方程比較容易求解，而關于x 、 y的方程則演化為我們熟悉的馬丟方程的形式。
