Recent Progress in Spin Glasses

N. Kawashima, H. Rieger

We review recent findings on spin glass models. Both the equilibrium properties and the dynamic properties are covered. We focus on progress in theoretical, in particular numerical…

Superconductor-to-Normal Phase Transition in a Vortex Glass Model: Numerical Evidence for a New Percolation Universality Class

Frank O. Pfeiffer, Heiko Rieger

The three-dimensional strongly screened vortex-glass model is studied numerically using methods from combinatorial optimization. We focus on the effect of disorder strength on the…

Numerical renormalization group study of random transverse Ising models in one and two space dimensions

Y. -C. Lin, N. Kawashima, F. Igloi +1

The quantum critical behavior and the Griffiths-McCoy singularities of random quantum Ising ferromagnets are studied by applying a numerical implementation of the Ma-Dasgupta-Hu re…

Critical Behavior and Griffiths-McCoy Singularities in the Two-Dimensional Random Quantum Ising Ferromagnet

C. Pich, A. P. Young, H. Rieger +1

We study the quantum phase transition in the two-dimensional random Ising model in a transverse field by Monte Carlo simulations. We find results similar to those known analyticall…

Griffiths-McCoy singularities in the transverse field Ising model on the randomly diluted square lattice

T. Ikegami, S. Miyashita, H. Rieger

The site-diluted transverse field Ising model in two dimensions is studied with Quantum-Monte-Carlo simulations. Its phase diagram is determined in the transverse field (Gamma) and…

Application of a continous time cluster algorithm to the Two-dimensional Random Quantum Ising Ferromagnet

H. Rieger, N. Kawashima

A cluster algorithm formulated in continuous (imaginary) time is presented for Ising models in a transverse field. It works directly with an infinite number of time-slices in the i…
