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…
Gapless inhomogeneous superfluid phase with spin-dependent disorder
M. Jiang, R. Nanguneri, N. Trivedi +2
We show that the presence of a spin-dependent random potential in a superconductor or a superfluid atomic gas leads to distinct transitions at which the energy gap and average orde…
Reversal-field memory in magnetic hysteresis
H. G. Katzgraber, F. Pazmandi, C. R. Pike +4
We report results demonstrating a singularity in the hysteresis of magnetic materials, the reversal-field memory effect. This effect creates a nonanalyticity in the magnetization c…
Reversal-Field Memory in the Hysteresis of Spin Glasses
H. G. Katzgraber, F. Pazmandi, C. R. Pike +4
We report a novel singularity in the hysteresis of spin glasses, the reversal-field memory effect, which creates a non-analyticity in the magnetization curves at a particular point…
Conducting phase in the two-dimensional disordered Hubbard model
P. J. H. Denteneer, R. T. Scalettar, N. Trivedi
We study the temperature-dependent conductivity and spin susceptibility of the two-dimensional disordered Hubbard model. Calculations of the current-current correlati…
Auxiliary-field Monte Carlo for Quantum Spin and Boson Systems
M. Ulmke, R. T. Scalettar
We describe a new algorithm for the numerical simulation of quantum spin and boson systems. The method is based on the Trotter decomposition in imaginary time and a decoupling by a…
