In the presence of symmetry-protection, topological invariants of topological phases of matter in free fermion systems, e.g., topological band insulators, can be directly computed via the properties of band structure. Nevertheless, it is usually difficult to extract topological invariants in strongly-correlated topological phases of matter in which band structure is not well-defined. One typical example is the fractional quantum Hall effect whose low-energy physics is governed by Chern-Simons topological gauge theory and Hall conductivity plateaus involve extremely fruitful physics of strong correlation. In this article, we focus on intrinsic topological order (iTO), symmetry-protected topological phases (SPT), and symmetry-enriched topological phases (SET) in boson and spin systems. Through gauge field-theoretical approach, we review some research progress on these topological phases of matter from the aspects of projective construction, low-energy effective theory and topological response theory.

表 1 二维投影构造中的部分子的拟设.
$ A1, A2,\cdots, A4 $ 代表四种拟设. 每条完全填充的能带由箭头和正负号标记. 箭头表示自旋方向, 正负号代表陈数为1或–1. A1一共有8条填满的陈-能带. A2和A3都有4条填满的陈-能带. A4只用到了f1, 一共有两条陈-能带被填满. 括号里成对的数字表示单个元胞里的费米子f1或f2的填充数: (自旋向上的费米子数目, 自旋向下的费米子数目).Table 1. Parton ansatzes in the two-dimensional projective construction.
$ A1,A2, \cdots, A4 $ stand for four different ansatzes respectively. Each fully occupied band is labeled by a pair of arrow and plus/minus sign. The arrow represents the spin eigenvalue of$ S^z $ , and$ \pm $ represents Chern number$ \pm1 $ . In A1, there are 8 fully occupied Chern bands; There are 4 fully occupied Chern bands in each of A2 and A3. In A4, flavor index is not involved, so only one flavor, say,$ f_1 $ is taken into account. And there are two filled Chern bands. A pair of integers denote the filling number of either$ f_1 $ and$ f_2 $ in each unit cell: (fermion number with up spin, fermion number with down spin).拟设 完全被$f_1$填充的陈-能带 完全被$f_2$填充的陈-能带 自旋矢量$q^T_s$ 电荷矢量$q^T_c$ $A1$ $\uparrow+, \downarrow+, \uparrow-, \downarrow-$ $(2, 2)$ $\uparrow+, \downarrow+, \uparrow-, \downarrow-$ $(2, 2)$ $\left(\dfrac{1}{2}~~-\dfrac{1}{2}~~\dfrac{1}{2}~~-\dfrac{1}{2}~~\dfrac{1}{2}~~-\dfrac{1}{2}~~\dfrac{1}{2}~~-\dfrac{1}{2}\right)$ $(1~~1~~1~~1~~1~~1~~1~~1)$ $A2$ $\uparrow+, \downarrow-$ $(1, 1)$ $\uparrow+, \downarrow-$ $(1, 1)$ $\left( {1}/{2}~~- {1}/{2}~~ {1}/{2}~~ -{1}/{2}\right)$ $(1~~1~~1~~1)$ $A3$ $\uparrow+, \downarrow-$ $(1, 1)$ $\downarrow+, \uparrow-$ $(1, 1)$ $\left(1/{2}~~- {1}/{2}~~- {1}/{2}~~ {1}/{2}\right)$ $(1~~1~~1~~1)$ $A4$ $\uparrow+, \downarrow-$ $(1, 1)$ 无 $\left( {1}/{2}~~- {1}/{2}\right)$ $(1~~1)$ 表 2 在大U极限下, 实空间每个格点上的不消耗U能量的占据状态形成了物理希尔伯特空间. 我们需要对费米子的总的填充数做限制. 限制之后, 所有格点都能够同时处于物理希尔伯特空间.

A brief summary of irreducible 3D SPT phases with unitary Abelian symmetry.
$ a^I $ and$ b^I $ are 1-form and 2-form$ {U(1)} $ gauge fields, respectively. “($ {\mathbb{Z}}_{N_{12}} $ )$ \cdots $ ”denote the corresponding classifications, where$ N_{IJ\cdots} $ are greatest common divisors of$ N_I, N_J, \cdots $ . SPT phases with either$ {\mathbb{Z}}_N $ or${U(1)}^k $ or$ {\mathbb{Z}}_N\times {U(1)}^k $ are trivial and not included below. By “irreducible”, we means that all subgroups of symmetry group play nontrivial roles in protecting the nontrivial SPT phases.
