Domain growth in Ising systems with quenched disorder.
We present results from extensive Monte Carlo (MC) simulations of domain growth in ferromagnets and binary mixtures with quenched disorder. These are modeled by the random-bond Ising model and the dilute Ising model with either nonconserved (Glauber) spin-flip kinetics or conserved (Kawasaki) spin-exchange kinetics. In all cases, our MC results are consistent with power-law growth with an expon...
متن کاملChapter 1 Frustration and Fluctuations in Systems with Quenched Disorder
As Phil Anderson noted long ago, frustration can be generally defined by measuring the fluctuations in the coupling energy across a plane boundary between two large blocks of material. Since that time, a number of groups have studied the free energy fluctuations between (putative) distinct spin glass thermodynamic states. While upper bounds on such fluctuations have been obtained, useful lower ...
متن کاملNoisy Transport in Reaction-diffusion Systems with Quenched Disorder
Reaction-diffusion (RD) models are useful tools for studying a wide variety of natural phenomena. The effects of quenched disorder in the reaction rates on RD models is not completely understood, especially in parameter regimes where internal noise or stochasticity is also important. In the first part of this dissertation, I will examine an RD model in which both quenched disorder and stochasti...
متن کاملDynamic phases of active matter systems with quenched disorder.
Depinning and nonequilibrium transitions within sliding states in systems driven over quenched disorder arise across a wide spectrum of size scales ranging from atomic friction at the nanoscale, flux motion in type II superconductors at the mesoscale, colloidal motion in disordered media at the microscale, and plate tectonics at geological length scales. Here we show that active matter or self-...
متن کاملCorrelation Inequalities for Quantum Spin Systems with Quenched Centered Disorder
Quantum spin system with quenched randomness are both important and theoretically challenging. They are widely used as models for metallic alloys in condensed matter physics, see [2] for a review. They are also important in combinatorial optimization problems especially in relation to quantum annealing procedures [3] and quantum error correcting codes [4]. One approach to studying such macrosco...
