Measuring glass entropies with population annealing
Christopher Amey, Jonathan Machta
We combine population annealing Monte Carlo and several thermodynamic integration techniques to measure equilibrium vibrational and configurational entropies in the metastable flui…
Dynamical Ising model of spatially-coupled ecological oscillators
Vahini Reddy Nareddy, Jonathan Machta, Karen C Abbott +2
Long-range synchrony from short-range interactions is a familiar pattern in biological and physical systems, many of which share a common set of ``universal'' properties at the poi…
Kinetic Ising Models with Self-interaction: Sequential and Parallel Updating
Vahini Reddy Nareddy, Jonathan Machta
Kinetic Ising models on the square lattice with both nearest-neighbor interactions and self-interaction are studied for the cases of random sequential updating and parallel updatin…
Equilibrium Microcanonical Annealing for First-Order Phase Transitions
Nathan Rose, Jonathan Machta
A framework is presented for carrying out simulations of equilibrium systems in the microcanonical ensemble using annealing in an energy ceiling. The framework encompasses an equil…
Effects of setting the temperatures in the parallel tempering Monte Carlo algorithm
Ignacio Rozada, Maliheh Aramon, Jonathan Machta +1
Parallel tempering Monte Carlo has proven to be an efficient method in optimization and sampling applications. Having an optimized temperature set enhances the efficiency of the al…
Absence of Chaotic Size Dependence for Spin Glasses on Hierarchical Lattices
Jeffrey Gertler, Jon Machta
We investigate the question of whether chaotic size dependence occurs on hierarichical lattices and demonstrate that it is not present in these systems. Our results show that the m…
