Quantum versus classical annealing: insights from scaling theory and results for spin glasses on 3-regular graphs [PDF]

open access: yes, 2015
We discuss an Ising spin glass where each $S=1/2$ spin is coupled antiferromagnetically to three other spins (3-regular graphs). Inducing quantum fluctuations by a time-dependent transverse field, we use out-of-equilibrium quantum Monte Carlo simulations

INVESTIGATING THE IMPACT OF ANNEALING TEMPERATURE ON THE MICROSTRUCTURE AND MECHANICAL PERFORMANCE OF SELECTIVELY LASER MELTED Ti6Al4V ALLOY [PDF]

open access: yesEuropean Journal of Materials Science and Engineering, 2023
This research addresses the metallurgical and mechanical response during the annealing of Ti6Al4V parts fabricated by selective laser melting. The as-manufactured Ti6Al4V exhibited a very fine α´ martensitic structure with low ductility of less than 10%.

Superconductivity and magnetism in RbxFe2-ySe2: Impact of thermal treatment on mesoscopic phase separation [PDF]

open access: yes, 2012
An extended study of the superconducting and normal-state properties of various as-grown and post-annealed RbxFe2-ySe2 single crystals is presented. Magnetization experiments evidence that annealing of RbxFe2-ySe2 at 413 K, well below the onset of phase ...

Study of E. coli Hfq's RNA annealing acceleration and duplex destabilization activities using substrates with different GC-contents [PDF]

open access: yes, 2012
Folding of RNA molecules into their functional three-dimensional structures is often supported by RNA chaperones, some of which can catalyse the two elementary reactions helix disruption and helix formation.

Ion implantation and low-temperature epitaxial regrowth of GaAs [PDF]

open access: yes, 1981
Channeling and transmission electron microscopy have been used to investigate the parameters that govern the extent of damage in ion‐implanted GaAs and the crystal quality following capless furnace annealing at low temperature (∼400 °C). The implantation‐
