摘要: Abstract We study the finite size corrections for magnetization and internal energy of 2d Ising model in a magnetic field by using transfer matrix techniques. compare these with functional form recently proposed Delfino LeClair–Mussardo temperature behaviour one-point functions integrable quantum theories. find perfect agreement between theoretical expectations numerical results. Assuming as an input our analysis we obtain relevant improvement precision continuum limit estimates both quantities.
