Low energy excitations in a long prism geometry: testing the lower critical dimension of the Ising spin glass
Massimo Bernaschi, Luis Antonio Fernández, Isidoro González-Adalid Pemartín +3
We propose a general method for studying systems that display low-energy excitations in their low-temperature phase. We argue that in a rectangular right-prism geometry (the 3-dime…
Microcanonical simulated annealing: Massively parallel Monte Carlo simulations with sporadic random-number generation
M. Bernaschi, C. Chilin, L. A. Fernandez +7
Numerical simulations of models and theories that describe complex systems such as spin glasses are becoming increasingly important. Beyond fundamental research, these computationa…
The QISG suite: high-performance codes for studying Quantum Ising Spin Glasses
Massimo Bernaschi, Isidoro González-Adalid Pemartín, Víctor Martín-Mayor +1
We release a set of GPU programs for the study of the Quantum () Spin Glass on a square lattice, with binary couplings. The library contains two main codes: MCQSG (that carr…
The Quantum Transition of the Two-Dimensional Ising Spin Glass: A Tale of Two Gaps
Massimo Bernaschi, Isidoro González-Adalid Pemartín, Víctor Martín-Mayor +1
Quantum annealers are commercial devices aiming to solve very hard computational problems named spin glasses. Just like in metallurgic annealing one slowly cools a ferrous metal, q…
How we are leading a 3-XORSAT challenge: from the energy landscape to the algorithm and its efficient implementation on GPUs
M. Bernaschi, M. Bisson, M. Fatica +4
A recent 3-XORSAT challenge required to minimize a very complex and rough energy function, typical of glassy models with a random first order transition and a golf course like ener…
