摘要: Abstract We develop truncated conformal space (TCS) technique for perturbations of c =1 field theories. use it to give the first numerical evidence validity non-linear integral equation (NLIE) derived from light-cone lattice regularization at intermediate scales. A controversy on quantization Bethe states is solved by this comparison and using locality principle ultraviolet fixed point. It turns out that correct pure hole one with half-integer quantum numbers originally proposed Fioravanti et al. [Phys. Lett. B 390 (1997) 243]. Once rule imposed, agreement between TCS NLIE be impressive.
