second quantization meaning in English

二次量子化

As we all know , the diagonalization of hamiltonian is an important procedure in solving the many - body problem in second quantization frame . usually we used the bogoliubov - valatin transformation method to diagonalization the hamiltonian that we were interesting in
众所周知，二次量子化框架下，多体物理系统哈密顿量的对角化步骤是非常重要的，通常我们都是使用bogoliubov - valatin变换对角化方法将被研究系统哈密顿量对角化。
In this paper , we first investigate the impurity effect ( ba2 + ) on the dielectric and phase transition properties in srtio3 within the framework of the transverse - field ising model ( tim ) . then a possible coupling mechanism between the magnetism and dielectric properties in eutio3 is discussed and the magnetic influence on the frequency of the soft - phonon mode is investigated via the heisenberg model , soft - mode theory under the mean field approximation , the second quantization theory and the perturbation theory . and we proceed further investigation on eu1 - xbaxtio3 of
我们发现baxeul _ xtio3 ( o ‘ x ‘ 0 . 2 )的介电常数和由内察的偏置场导致的电极化除了随杂质浓度产生相应的变化，同时在磁和介电性质的藕合作用影响下在低温下偏离通常的量子顺电体行为，在尼尔温度附近出现异常，且磁场通过对最近邻自旋关联的作用来影响介电常数和电极化。
