The Boundary Conformal Field Theories of the 2D Ising critical points [PDF]
Smain Balaska, Nahed Sihem BounouaWe present a new method to identify the Boundary Conformal Field Theories (BCFTs) describing the critical points of the Ising model on the strip. It consists in measuring the low-lying excitation energies spectra of its quantum spin chain for different boundary conditions and then to compare them with those of the different boundary conformal field theories of the $(A_2,A_3)$ minimal model.View original: http://arxiv.org/abs/1104.1104
