introduction
- first review the minimal models page
- Weber functions and conformal field theory
- rank 1 case
Ising model as a minimal model
- 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
- \(m= 3\)
- \(c = 1-{6\over m(m+1)} = \frac{1}{2}\)
- \(h_{p,q}(c) = {(4p-3q)^2-1 \over 48}\)
- \((p,q)=(1,1), (2,1), (2,2)\) or \((p,q)=(1,2), (1,3), (2,3)\)
- possible values of \(h\)
- \(0, 1/2, 1/16\)
graded dimensions
- associated chiral algebra has three irreducible modules with the following graded dimensions h=0, \(\chi_0=\chi _{1,1}^{(3,4)}=q^{-1/48}(1+q^2+q^3+2q^4+2q^5+3q^6+\cdots)\) h=1/2, \(\chi_{\epsilon}=\chi_{1,3}^{(3,4)}=q^{23/48}(1+q+q^2+q^3+2q^4+2q^5+3q^6+\cdots)\) h=1/16, \(\chi_{\sigma}=\chi _{1,2}^{(3,4)}=q^{1/24}(1+q+q^2+2q^3+2q^4+3q^5+4q^6+\cdots)\)
- Rocha-Caridi character[RC84] bosonic characters of Virasoro minimal models(Rocha-Caridi formula)
\(\chi_{\sigma}=\chi _{1,2}^{(3,4)}=\chi _{2,2}^{(3,4)}=\frac{\eta (2\tau )}{\eta (\tau )}=q^{1/24}\sum _{m=-\infty }^{\infty } (-1)^mq^{3 m^2- m }=q^{1/24}\sum_{n\geq 0}\frac{q^{n(n+1)/2}}{(1-q)(1-q^2)\cdots(1-q^n)}\)
\(\mathfrak{f}_2(\tau)=\sqrt{2}\frac{\eta(2\tau)}{\eta(\tau)}=\sqrt{2}q^{1/24} \prod_{n=1}^{\infty} (1+q^{n})=\sqrt{2}q^{1/24}\sum_{n\geq 0}\frac{q^{n(n+1)/2}}{(1-q)(1-q^2)\cdots(1-q^n)}\)
modularity of graded dimensions
\(\chi_M(-1/\tau)=\sum_{N} S_{M,N}\chi_N(\tau)\)
\(\chi_M(\tau+1)=\sum_{N} T_{M,N}\chi_N(\tau)\)
\(T=\left(\begin{array}{ccc}e^{-\pi i/24} & 0 & 0 \\ 0 & e^{23\pi i/24} & 0 \\ 0 & 0 & e^{\pi i/12}\end{array} \right)\)
