dc.description.abstractIn this paper we apply an analytical real-space renormalization group formulation which is based on numerical concepts of the density-matrix renormalization group, Within a rigorous mathematical framework we construct nonperturbative renormalization group transformations for the spin-1/2 XXX Heisenberg model in the finite-temperature regime. The developed renormalization group scheme allows for calculating the renormalization group flow behavior in the temperature-dependent coupling constant. The constructed renormalization group transformations are applied within the ferromagnetic and the antiferromagnetic regime of the Heisenberg chain. The ferromagnetic fixed point is computed and compared to results derived by other techniques.
