Diffusion-limited reactions on a two-dimensional lattice with binary disorder
Diffusion-limited reactions two-dimensional lattice with binary disorder

Reaction-diffusion systems where transition rates exhibit quenched disorder are common in physical and chemical systems. We study pair reactions on a periodic two-dimensional lattice, including contin...
Optical Properties of (SrMnO3)n/(LaMnO3)2n superlattices: an insulator-to-metal transition observed in the absence of disorder
Optical Properties insulator-to-metal transition absence of disorder
2010/11/23
We measure the optical conductivity 1(!) of (SrMnO3)n/(LaMnO3)2n superlattices (SL) for
n = 1, 3, 5, and 8 and 10 < T < 400 K. Data show a T -dependent insulator to metal transition
(IMT) for n 3...
Single and two-particle energy gaps across the disorder-driven superconductor-insulator transition
Single two-particle energy gaps disorder-driven superconductor-insulator transition
2010/11/23
The competition between superconductivity and localization raises profound questions in condensed matter physics. In spite of decades of research, the mechanism of the superconductorinsulator transiti...
Effects of Disorder on the Exchange Coupling in (Ga,Mn)As Diluted Magnetic Semiconductors
Disorder Exchange coupling Diluted magnetic semiconductors
2010/8/26
A theoretical study of the effects of disorder on the Mn-Mn exchange interactions for Ga1¡xMnxAs diluted magnetic semiconductors is presented. The disorder is intrinsically considered in the cal...
Ordering Due to Disorder in Frustrated Quantum Magnetic Systems
Quantum Magnetic frustrated magnetic systems
2010/4/16
The phenomenon of order by disorder in frustrated magnetic systems is reviewed. Disorder (thermal or quantum fluctuations) may sometimes give rise to long range ordering in systems with frustration, w...
