"Integrable perturbations of Ising model"의 두 판 사이의 차이

2012년 11월 1일 (목) 12:47 판

energy perturbation [Kau49], [MTW77]
- related to A1
- Ising field theory
magnetic perturbation[Zam89]
- related to E8

the continuum limit of the Ising model is made to look like a field theory only through the application of a certain transformation (Jordan-Winger)
- "kink" states (boundaries between regions of differing spin) = basic objects of the theory
- called quasiparticle

Soon after Zamolodchikov’s first paper [Zam] appeared,
Fateev and Zamolodchikov conjectured in [FZ90] that
- if you take a minimal model CFT constructed from a compact Lie algebra g via the coset construction and perturb it in a particular way, then you obtain the affine Toda field theory (ATFT) associated with g, which is an integrable field theory.
- This was confirmed in [EY] and [HoM].

If you do this with g = E8, you arrive at the conjectured integrable field theory investigated by Zamolodchikov and described in the previous paragraph.
That is, if we take the E8 ATFT as a starting point, then the assumptions (Z1)–(Z4) become deductions.
