Today we can only imagine about our first teacher who blames us may only just for an unnamed case through the survival of our childhood's memory ,also,it is hard to find such a kind of feeling to describe my heart when I obtain high mark in my middle school's time,cause we will never know there are so much frustration in our future,we really miss too much mirth which should belong to us, before the boom is found,the vernal flower has been seared stealthily ,and our college's time is also fleeting within a seirous of chemic reactions,similarly ,it is difficult to remind you of some rememberable things,even if we have been moved by him at that time,what's more,and many close buddies yesterday whose silhouette is being becoming darker and darker...

现在的我们只能通过儿时残存的记忆,大概的猜出第一位批评我们的老师,可能仅仅是为了一件说不出名的小事;也很难找到一种情怀来形容中学时代取得一系列傲人成绩的心情了,因为那时的我们永远不会知道,今后的路途如此的坎坷,我们实在是错过了太多原本属于我们的欢笑,青春的花朵在我们还没有察觉到它开放时就悄悄的枯萎了;我们的大学时光也在一系列化学反应中飞逝着,很难记起一些值得记起的事情来,哪怕当时你曾经为他会心一笑;还有那么多曾经在身旁出生入死的好兄弟,他们背影也开始变的模糊起来。。。

By employing the Jordan-Wigner transformation and a modified mean field method, we are able to determine its ground-state quantum phase diagram approximately. The chapter IV is the main part of this Thesis. It contains the main innovations in our work. We propose and study in detail a S=1 Ising chain with the interplay of single-ion anisotropy and dimerization. The main results and innovations are the following: We show that the total number of the zero-component of spins at each site is a conserved quantity. This quantity, which may intuitively called as hole's quantum number, is hidden in the system. We show further that the hole's number in the ground-state is zero; By using the Jordan-Wigner transformation, we map this model onto a series of subsystems described by the spin 1/2 dimerized transverse Ising model. We solve the subsystems exactly, by presenting the exact wave functions and spectra;We show that this system exhibits a series of quantum phase transitions by varying the dimerization strength. We determine the quantum critical points exactly. We also show that the criticality is the same as that of the uniform S = 1/2 transverse Ising chain.

第四章是本文的重点及主要创新内容,我们具体研究了自旋为1的在横向单离子晶格场中的一维二聚化Ising链,我们得到的主要结果和创新之处是:(1)证明了这一模型具有一种隐藏的对称性,即自旋第三分量为零的格点数目是一个守恒量,并证明基态出现在空穴数目为零的子空间中;(2)利用Jordan-Wigner 变换将此模型变换到一系列自旋为1/2的横磁场中的二聚化Ising 模型,并给出了相应严格的波函数及能谱;(3)我们发现系统的基态随着二聚化强度的变化将呈现出一系列量子相变,我们得到了量子临界点的精确位置,并证明其临界性质与自旋为1/2的横磁场中的均匀Ising 链中的临界行为属于同一普适类。
