### Explicit Examples of Conformal Invariance

- Mathematics
- 2001

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

- Mathematics
- 1986

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

- Physics
- 1986

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…
