  1. In quantum chromodynamics ( qcd ), vacuum is not trivial, that is, vacuum carry quantum numbers. such a behavior is embodied by non - perturbative con - densates of quarks and gluons. since hadrons are excitations with respect to the vacuum, hadronic properties are ultimately related to properties of the vacuum. based on the vacuum structure, some hadron properties have been described well. in the low energy region, qcd has two very important proper - ties : chiral symmetry spontaneous breaking and confinement, which are closely related to the vacuum characteristics of qcd. much experiments and theoretical studies have shown that chiral symmetry spontaneous breaking is very important to understand the low - energy feature of the strongly interacting physics, and the quark condensates give an expression to chiral symmetry spontaneous breaking. according to goldstone ' s theorem, the goldstone bosons with zero mass will emerge as the chiral symmetry is spontaneously broken. there are two ways : inear and non - linear methods to carry out this constraint. in our paper, we will use the non - linear method

    大量實驗和理論研究表明，手征對稱自發破缺對于理解低能強相互作用十分重要，而夸克凝聚又是導致手征對稱自發破缺的因素。按goldstone理論，伴隨手征對稱自發破缺應該會有零質量的goldstonebosons產生。而對于這一條件的實現有線性和非線性兩種方法本文將用非線性的方法將手征對稱自發破缺應用於su （ 3 ）模型即重子八重態，得出描述其強相互作用的手征對稱自發破缺lagrange密度。
  2. Spontaneous emission can be totally suppressed or strongly enhanced depending on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density. several novel phenomena can be obtained. the spontaneous emission displays an oscillatory behavior, classical light localization, photon - atom bound state, nonzero steady - state population and anomalously large vacuum rabi splitting. and localized mode associated with a defect site in an otherwise perfect photonic crystals, acts as a high - q micro - cavity

  3. Abstract : we have studied the spontaneous emission from a three - level atom with an external - driving field in a photonic crystal. as a result of quantum interference and photon localization, the population in the two upper levels displays quasi - oscillatory oroscillatory behavior. this depends on the initial atomic state and the relative positions of the two upper levels from the forbidden gap. the intensity and the phase of the external field can affect spontaneous emission from the atom. the properties are different from a three - level atom either in vacuum or in aphotonic crystal without an external driving field

    文摘:討論了在雙光子驅動場作用下，三能級原子在光子晶體中的自發發射問題.由於量子干涉和光的局域化作用，兩個上能級中的占據數將具有周期振蕩或準周期振蕩的性質，這不僅依賴于兩個上能級與禁帶的相對位置，同時也依賴于原子的初始狀態，而且還與驅動場的強度、驅動場的入射位相有關.這些性質既與真空中帶有驅動場的原子的自發發射性質不同，也有別于無驅動場作用下光子晶體中三能級原子的自發發射性質
  4. Thesis home analyzed its characteristic of marketable behavior as economic man. this article especially pointed out following, investment fund is n ' t provided with spontaneous tendency to stable capital market, but along with expansion o

    本文特別指出的是，基金在本性上並不具有穩定資本市場的自發傾向，但是隨著投資基金規模的擴大，基金在基金管理人之間產生搏弈的時候，卻能對資本市場的活動產生穩定的客觀作用。
  5. Through the calculation of the electromagnetic green ' s function, we investigate the spontaneous emission behavior from atoms in one - dimensional photonic crystal. we found that the pc effect may lead to the coexistence of both accelerated and inhibited decay processes

    通過計算一維光子晶體中電磁場的green函數，我們考察了一維光子晶體中原子自發發射的壽命分佈，發現光子晶體效應能使原子自發發射速率加快或減慢。
