Short-range order in bulk Zr- and Hf-based amorphous alloys
(Elsevier Science Sa, 2000-02)
The local order in mechanically alloyed Hf65Al7.5Cu17.5Ni10 and Zr65Al7.5Cu17.5Ni10 amorphous alloys was studied by means of perturbed angular correlation measurements. The amorphous state of the starting material was ...
Short-range order in linear binary alloys: Delocalization of states versus memory of ordered band structures
(American Physical SocCollege PkEUA, 1996)
A new approach to the electronic structure of two dimensional disordered alloys
(Elsevier B.V., 1995-06-01)
We propose a novel method to calculate the electronic Density of States (DOS) of a two dimensional disordered binary alloy. The method is highly reliable and numerically efficient, and Short Range Order (SRO) correlations ...
Short-range Ising spin glasses: a critical exponent study
(1998)
The critical properties of short-range Ising spin-glass models, defined on diamond hierarchical lattices of graph fractal dimensions df=2.58,3, and 4, and scaling factor 2, are studied via a method based on the Migdal–Kadanoff ...

Tunable visible photoluminescence of powdered silica glass
(Elsevier B.V., 2008-01-15)
intense photoluminescence in the visible region was observed at room temperature in standard soda-lime-silica glass powder, mechanically milled in a high-energy attrition mill. The emission band maximum shows an interesting ...

Chaos signatures in the short and long time behavior of the Out-of-Time ordered correlator
(American Physical Society, 2018-11)
Two properties are needed for a classical system to be chaotic: exponential stretching and mixing. Recently, out-of-time order correlators were proposed as a measure of chaos in a wide range of physical systems. While most ...
Mutual information identifies spurious Hurst phenomena in resting state EEG and fMRI data
(American Physical Society, 2018-02)
Long-range memory in time series is often quantified by the Hurst exponent H, a measure of the signal's variance across several time scales. We analyze neurophysiological time series from electroencephalography (EEG) and ...
