Explicit Examples of Conformal Invariance
We study examples where conformal invariance implies rational critical indices, triviality of the underlying quantum field theory, and emergence of hypergeometric functions as solutions of the field
Infinite dimensional lie algebras in conformal QFT models
The “minimal theories” of critical behaviour in two dimensions of Belavin, Polyakov and Zamolodchikov are reviewed. Conformally invariant operator product expansions (OPEs) are written down in terms
Conformal invariance and non-universality in quantum spin chains with a defect
The authors study quantum analogues of two-dimensional Ising models with a linear defect. Conformal invariance and scaling arguments are used to relate the exponent eta * (of the time correlation
