The description of the numerical method of simulation based on the quantum transfer-matrix (QTM) approach is presented for diluted spin \(S=1/2\) chains. Modification of the extrapolation technique has been used to obtain better accuracy of numerical

The numerical transfer-matrix approach and the exact diagonalization technique are worked out for the isotropic Heisenberg model with the uniform and alternating spin variables within the ring geometry. They are applied in large-scale simulations to

The experimental field-dependent specific heat of the polydomain pure Yb4As3 and diluted (Yb1−xLux)4As3 (x = 0.01, 0.03) systems is presented and compared with that calculated by the numerical quantum transfer-matrix method. The simulations have be
