introduction
Ising model as a minimal model
- first review the minimal models page
- Ising model is a unitary minimal model and thus can be understood by the representation of Viraroso algebra
- the representation is given by following data
\(m= 3\)
central charge \(c = 1-{6\over m(m+1)} = \frac{1}{2}\)
\(h_{p,q}(c) = {(4p-3q)^2-1 \over 48}\)
\(p= 1,2\), \(q = 1,\cdots p\)
\((p,q)=(1,1), (2,1), (2,2)\) - possible values of \(h\)
\(0, 1/2, 1/16\)
graded dimensions
- associated chiral algebra has three irreducible modules with the following graded dimensions
\(\chi_0=q^{-1/48}(1+q^2+q^3+2q^4+2q^5+3q^6+\cdots)\)
\(\chi_{\epsilon}=q^{23/48}(1+q+q^2+q^3+2q^4+2q^5+3q^6+\cdots)\)
\(\chi_{\sigma}=q^{1/24}(1+q+q^2+2q^3+2q^4+3q^5+4q^6+\cdots)\) - Rocha-Caridi character[RC84]
modularity of graded dimensions
\(\chi_M(-1/\tau)=\sum_{N} S_{M,N}\chi_N(\tau)\)
\(\chi_M(\tau+1)=\sum_{N} T_{M,N}\chi_N(\tau)\)
\(T=\left(\begin{array}{ccc}e^{-\pi i/24} & 0 & 0 \\ 0 & e^{23\pi i/24} & 0 \\ 0 & 0 & e^{\pi i/12}\end{array} \right)\)
\(2S=\left(\begin{array}{ccc}1 & 1& \sqrt{2} \\ 1 & 1 & -\sqrt{2} \\ \sqrt{2} & -\sqrt{2} & 0\end{array} \right)\)
matching two sets of funtions
\(f(\tau)=\frac{e^{-\frac{\pi i}{24}}\eta(\frac{\tau+1}{2})}{\eta(\tau)}=q^{-1/48} \prod_{n=1}^{\infty} (1+q^{n-\frac{1}{2}})\)
\(\chi_0+\chi_{\epsilon}\)
{1, 0, 0, 1, 0, 1, 0, 1, 1, 1, 1, 1, 2, 1, 2, 2, 3, 2, 3, 3, 4}

\(\chi_0=q^{-1/48}(1+q^2+q^3+2q^4+2q^5+3q^6+\cdots)\)
\(\chi_{\epsilon}=q^{23/48}(1+q+q^2+q^3+2q^4+2q^5+3q^6+\cdots)\)
{1, 0, 0, 1, 0, 1, 0, 1, 1, 1, 1, 1, 2, 1, 2, 2, 3, 2, 3, 3, 4}

{2,-1,0,0,1,0,1,0,3,...} -> \(q^{-1/48}}(1-1/2q^{1/2}+q^{4/2}+q^{6/2}+3q^{8/2}+\cdots)\)
