we derive the spectrum of low-lying eigenvalues of Baxter's corner transfer matrix. Its relation to the spectrum of the usual transfer matrix, its scaling properties and the way the conformal anomaly enters, are discussed.
Abstract
We study two-dimensional Ising systems at the critical point. Using conformal considerations we derive the spectrum of low-lying eigenvalues of Baxter's corner transfer matrix. Its relation to the spectrum of the usual transfer matrix, its scaling properties and the way the conformal anomaly enters, are discussed.
