Haematite natural crystals: non-linear initial susceptibility at low temperature

Glassy Crystals Low-frequency and Low-temperature Properties a

Glasses are amorphous like liquids, but are rigid like crystals. To a chemist, this may seem natural: silicon dioxide, when covalently bonded into a well-relaxed random network, should resist deformations as an elastic solid just as it would in a crystalline network. To a theoretical physicist, this is more mysterious. What broken symmetry’ causes the rigidity‘! Of course, the chemist may in th...

Green Method for Synthesizing Gallium Nitride Nanostructures at Low Temperature

Gallium nitride (GaN) nanostructures (NS) were synthesized using pulseddirect current plasma enhanced chemical vapor deposition (PDC-PECVD) on quartzsubstrate at low temperature (600°C). Gallium metal (Ga) and nitrogen (N) plasma wereused as precursors. The morphology and structure of the grown GaN NS werecharacterized by field emission scanning electron microscope (FE-SEM), transmissionelectro...

Non-linear Evolution and Parton Distributions at Low X

We suggest a new procedure for extrapolating the parton distributions from HERA to much higher energies. The procedure suggested consists of two steps. First, we solve the non-linear evolution equation. Second, we introduce a correcting function for which we write a DGLAP-type linear evolution equation. The nonlinear equation is solved numerically and estimates for the saturation scale, as well...
