Optimization and benchmarking of the thermal cycling algorithm
Amin Barzegar, Anuj Kankani, Salvatore Mandrà +1
Optimization plays a significant role in many areas of science and technology. Most of the industrial optimization problems have inordinately complex structures that render finding…
Computational Overhead of Locality Reduction in Binary Optimization Problems
Elisabetta Valiante, Maritza Hernandez, Amin Barzegar +1
Recently, there has been considerable interest in solving optimization problems by mapping these onto a binary representation, sparked mostly by the use of quantum annealing machin…
Numerical observation of a glassy phase in the three-dimensional Coulomb glass
Amin Barzegar, Juan Carlos Andersen, Moshe Schechter +1
The existence of an equilibrium glassy phase for charges in a disordered potential with long-range electrostatic interactions has remained controversial for many years. Here we con…
Distribution of interevent avalanche times in disordered and frustrated spin systems
John Ferre, Amin Barzegar, Helmut G. Katzgraber +1
Hysteresis loops and the associated avalanche statistics of spin systems, such as the random-field Ising and Edwards-Anderson spin-glass models, have been extensively studied. A pa…
