Dynamical CPA approach to an itinerant fermionic spin glass model
Abstract. We study a fermionic version of the Sherrington-Kirkpatrick model including nearest-neighbor hopping on a ∞-dimensional simple cubic lattices. The problem is reduced to one of free fermions moving in a dynamical effective random medium. By means of a CPA method we derive a set of self-consistency equations for the spin glass order parameter and for the Fourier components of the local ...
متن کاملDynamical solutions of a quantum Heisenberg spin glass model
Abstract. We consider quantum-dynamical phenomena in the SU(2), S = 1/2 infinite-range quantum Heisenberg spin glass. For a fermionic generalization of the model we formulate generic dynamical selfconsistency equations. Using the Popov-Fedotov trick to eliminate contributions of the non-magnetic fermionic states we study in particular the isotropic model variant on the spin space. Two complemen...

متن کاملRenormalization group approach to spin glass systems
A renormalization group transformation suitable for spin glass models and, more generally, for disordered models, is presented. The procedure is non-standard in both the nature of the additional interactions and the coarse graining transformation, that is performed on the overlap probability measure. Universality classes are thus naturally defined on a large set of models, going from Z 2 and Ga...
متن کاملA New Approach to Spin Glass Simulations
We present a recursive procedure to calculate the parameters of the recently introduced multicanonical ensemble and explore the approach for spin glasses. Temperature dependence of the energy, the entropy and other physical quantities are easily calculable and we report results for the zero temperature limit. Our data provide evidence that the large L increase of the ergodicity time is greatly ...
