The first aspect is about the distribution function for fermions in quasi - equilibrium qgp which is perturbed by the fluctuation of the color field . neglecting the affect of the spin and the collision between the particles in qgp , the distribution function for fermions in quasi - equilibrium qgp has been obtained . further more , the physical “ basses that decide the departure factor are analyzed 第一,從qgp動力論出發,忽略自旋和碰撞效應,得到qgp在色場漲落擾動下偏離平衡態而處于近平衡時的分布函數的二級近似以及偏離因子的物理表示,進而分析了決定偏離因子的物理因素。

Firstfy , one - dimensional spin - 1 / 2 jordan - wigner transformation is introduced detailedly , which maps spins onto spinfess fermions . next , we discuss the statistical relations of spin operators by means of this mapping . moreover , from these relations we can notice that the s = l / 2 spin operators partly resemble fermi operators , and as well as , they partly resemble bose operators 接著,基于無自旋費米子表象,我們討論了自旋算符所遵循的統計關系,并由此看出自旋- 1 2的自旋算符既部分地相似于費米子算符,又部分地相似于玻色子算符。

For the past few years , after flipping through and careful reading of astronomical and scientific journals and websites , my thought on dark energy is just like what richard feynman tried to explain to his colleagues in caltech why boson had integer spins and fermion had half - integer spins 經過這幾年翻閱及細讀天文及科學期刊及有關網頁,筆者對暗黑能量的感想,就如同費曼對他在加州理工的同事嘗試解釋為何玻色子自旋為整數的粒子而費米子自旋為半整數的粒子時一樣。

Quantum system is classified as fermi system and bose system according the statistics of its particles . correspondingly for electron and photon transmission we discuss the classical capacities of fermion channels and boson channel in chapter 2 and chapter 3 respectively 量子系統通常根據其粒子的統計性質分為費米系統和玻色系統,在第二、三章我們將分別討論電子傳輸的費米信道經典容量和光子傳輸的玻色信道經典容量。

Based upon this transformation , we introduce another form of one - dimensional spin - 1 / 2 jordan - wigner transformation that maps the pauh spin operators onto the real majorana lattice fermions . next , its application in one - dimensional quantum ising spin chain model is displayed 基于該變換,我們介紹了另一種形式的一維自旋- 1 2的“ jordan - wigner ”交換,即用實的“ mbjorana ”格點費米子來描述泡利自旋算符。

In order to include fermions in string theory , there must be a special kind of symmetry called supersymmetry , which means for every boson ( particle that transmits a force ) there is a corresponding fermion ( particle that makes up matter ) 為了將費米子列入弦理論中,必須有一種特殊的對稱即超對稱,這意味著每一個玻色子(能夠傳力的粒子)都有有一個相應的費米子(組成事物的粒子) 。

We commute the jacobian phase of the integral measure under the chiral rotation , we also discuss the fermion determent of the non - commutative chiral qcd2 model and provide the effective action of the non - commutative chiral qcd2 model 我們用fujikawa路徑積分的方法研究了二維非對易空間的手征qcd _ 2模型作用量費米子部分在手征轉動下所產生的手征反常。

In chapter we give out an explicit expression of classical capacity of general fermi quantum channel for single mode fermion system under the restriction of input average occupation numbers of fermions ( that is the input power restriction ) 第二章給出了輸入費米子平均占據數限定(平均輸入功率限定)的條件下的單模費米系統量子信道的經典容量。

Fermions are the basic building blocks of ordinary matter and include electrons , protons and neutrons individually , as well as atoms with an odd number of those constituents 費米子是一般物質的基本構成單位,個別的電子、質子、中子以及由奇數個這些粒子組成的原子都屬于費米子。

Unlike bosons , fermions are misanthropes ; the pauli exclusion principle prohibits them from existing in the same quantum state 費米子與玻色子不同,它們喜歡離群索居,包立不相容原理禁止它們處于同一個量子狀態。

Then , we introduce the double - fermion representation of one - dimensional isotropic xy spin - 3 / 2 chain model 最后,我們介紹了一維各向同性xy自旋- 3 2鏈模型的雙費米子表象。

She showed that her fermions did not exist as molecules ? that is , they had not become chemically bound together 不過費米凝聚的困難之處在于如何去觀察它。

Mass is really a coupling between a left handed fermion and a right handed fermion 電子與電子中微子,以及在第二、三代中相對應的粒子,被統稱為輕子。

In a system , no two fermions can occupy the same quantum state ( position and velocity ) 在一系統中,不能有兩粒費米子?據相同的量子態(位置與速度)

The weak charge of fundament fermions 費米子的弱荷

Particles, such as electrons, requiring antisymmetric wave functions are called fermions . 要求反對稱波函數的粒子,如電子,叫做費米子。
