Differential Real Space Renormalization : the Linear Ising Chain
The differential real space renormalization method, recently introduced by Hilhorst et al., is applied to the linear Ising chain. It is shown that chains with spatially homogeneous as well as inhomogeneous or quenched random interactions can be treated. For the first two cases the free energy is computed by renormalization. The discussion includes also the case with a magnetic field, higher ord...
متن کاملTime-Dependent Real-Space Renormalization Group Method
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...
متن کاملReal-space renormalization group for the random-field Ising model.
We present real–space renormalization group (RG) calculations of the critical properties of the random–field Ising model on a cubic lattice in three dimensions. We calculate the RG flows in a two–parameter truncation of the Hamiltonian space. As predicted, the transition at finite randomness is controlled by a zero temperature, disordered critical fixed point, and we exhibit the universal cross...

متن کاملMinimalistic real-space renormalization of Ising and Potts Models in two dimensions
We introduce and discuss a real-space renormalization group (RSRG) procedure on very small lattices, which in principle does not require any of the usual approximations, e.g., a cut-off in the expansion of the Hamiltonian in powers of the field. The procedure is carried out numerically on very small lattices (4×4 to 2×2) and implemented for the Ising Model and the q = 3,4,5-state Potts Models. ...
