zero spin 中文意思是什麼
zero spin
解釋
零自旋-
And then, we specially study the effect of spin interaction ' s anisotropy on the critical temperature tc. from what we have observed we suggest that the critical temperatur tc grows as the anisotropy intensifies, while the system magnetization becomes weaker. the system becomes id if the anisotropy ratio r goes to infinity, and its equilibrium state keeps zero magnetization at any finite temperature, which confirm that there is no observable transition for id system
其後，著重研究了自旋相互作用的各向異性程度r對其臨界溫度t _ c的影響，總結出：隨著系統各向異性程度的增強，系統的臨界溫度向高溫轉移，而系統的磁化強度在不斷的減弱；當r趨近於無窮大時，系統演變為一維系統，系統在任何有限溫度下達到的平衡態始終保持磁化強度為零，這也證實了一維系統不發生相變 -
In terms of the measure of entanglement called " negativity ", the thermal entanglement in a two - qubit spin - 1 system with two spins coupled by exchange interaction is investigated, we find that there is a segment for j in which the entanglement is zero, moreover the segment increases with t, this is different from the cases of the spin - 1 / 2
應用糾纏度對高維度系統的度量方法- - - 「 negativity 」 ，我們研究了自旋等於1的兩量子比特系統的熱糾纏，我們還發現在耦合常數一般區域糾纏度為零，這個結論和自旋等於1 2的情況是不同的。 -
After a long time evolution, the system finally reaches a stable state at which the magnetization and the equal time spin - pair correlation are periodic oscillating functions with the equal period as the external field. numerical simulation shows : when the amplitude of external filed is large, there exits a particular temperature at which the average magnetization and the average spin - pair correlation are almost unaltered with various field amplitude ( i. e. magnetic susceptibility is zero ), and the particular temperature depends on the number of the spin states, cutting down with q increasing
由數值模擬得到：當外場幅度較大時，存在一個特殊的溫度點（我們稱之t ） ，在這個溫度點，系統的平均磁化強度和平均等時自旋對關聯隨外場幅度的變化幾乎保持不變（即磁化率為零） ，並且這個溫度的大小依賴于自旋態數目q的變化， q越大，這個溫度就越小；而當外場較小時，確信系統存在有限大小的臨界溫度 -
The improved theory have succeeded in applying to gaussian model. in the third chapter, based on the single - spin transition dynamics, we discuss the time evolution of the local magnetization in the anisotropic three - dimensional xy model under the zero external field
第三章在單自旋躍遷臨界動力學的基礎上，討論零場下三維（ 3d ）各向異性晶格上xy模型的局域磁化強度的時間演化。
