Cluster moves with an entropic reservoir accelerate low-temperature simulations of three-dimensional spin glasses
Claudio Chilin, Enzo Marinari, Víctor Martín-Mayor +3
We present an algorithm for the simulation of three-dimensional spin glasses deep in the low-temperature phase: Parallel Tempering enhanced with Houdayer moves and with an entropic…
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…
Shortcuts of freely relaxing systems using equilibrium physical observables
Isidoro González-Adalid Pemartín, Emanuel Mompó, Antonio Lasanta +2
Many systems, when initially placed far from equilibrium, exhibit surprising behavior in their attempt to equilibrate. Striking examples are the Mpemba effect and the cooling-heati…
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…
