Ground-state properties of the two-dimensional SWAP spin-glass ensemble
Alexander K. Hartmann, Leticia F. Cugliandolo, Marco Tarzia
We study the recently introduced SWAP ensemble for Ising spin-glasses, where the spins obtain varying lengths, with length scale . The lengths can be exchanged in the…
Level statistics in the fractal phase of generalized Rosenzweig--Porter models
Victor Delapalme, Leticia F. Cugliandolo, Alexander K. Hartmann +2
The Rosenzweig--Porter (RP) random matrix ensemble has emerged as a minimal model for the integrability-to-chaos crossover in quantum many-body systems. Its phase diagram features…
Fractal dimension of domain walls in two-dimensional Ising spin glasses
O. Melchert, A. K. Hartmann
We study domain walls in 2d Ising spin glasses in terms of a minimum-weight path problem. Using this approach, large systems can be treated exactly. Our focus is on the fractal dim…
Overcoming system-size limitations in spin glasses
Helmut G. Katzgraber, Mathias Koerner, Frauke Liers +1
In order to overcome the limitations of small system sizes in spin-glass simulations, we investigate the one-dimensional Ising spin chain with power-law interactions. The model has…
Universality-class dependence of energy distributions in spin glasses
Helmut G. Katzgraber, Mathias Koerner, Frauke Liers +2
We study the probability distribution function of the ground-state energies of the disordered one-dimensional Ising spin chain with power-law interactions using a combination of pa…
Reduction of Two-Dimensional Dilute Ising Spin Glasses
S. Boettcher, A. K. Hartmann
The recently proposed reduction method is applied to the Edwards-Anderson model on bond-diluted square lattices. This allows, in combination with a graph-theoretical matching algor…
