Random-field-induced disordering mechanism in a disordered ferromagnet: Between the Imry-Ma and the standard disordering mechanism
Juan Carlos Andresen, Helmut G. Katzgraber, Moshe Schechter
Random fields disorder Ising ferromagnets by aligning single spins in the direction of the random field in three space dimensions, or by flipping large ferromagnetic domains at dim…

Effective optimization using sample persistence: A case study on quantum annealers and various Monte Carlo optimization methods
Hamed Karimi, Gili Rosenberg, Helmut G. Katzgraber
We present and apply a general-purpose, multi-start algorithm for improving the performance of low-energy samplers used for solving optimization problems. The algorithm iteratively…

Patch-planting spin-glass solution for benchmarking
Wenlong Wang, Salvatore Mandrà, Helmut G. Katzgraber
We introduce an algorithm to generate (not solve) spin-glass instances with planted solutions of arbitrary size and structure. First, a set of small problem patches with open bound…
