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…
Random quantum magnets with broad disorder distribution
D. Karevski, Y-C. Lin, H. Rieger +2
We study the critical behavior of Ising quantum magnets with broadly distributed random couplings (J), such that , , for large (Lévy fl…
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…
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…
Finite Size Scaling Analysis of Exact Ground States for +/-J Spin Glass Models in Two Dimensions
N. Kawashima, H. Rieger
With the help of EXACT ground states obtained by a polynomial algorithm we compute the domain wall energy at zero-temperature for the bond-random and the site-random Ising spin gla…
