In the last few years Berry phase in a single particle system has been studied very well, both theoretically and experimentally. However, the study of Berry phase in an entangled state has become a topic of interest very recently [1, 2, 3, 4, 5]. As entanglement is a striking feature of quantum systems and is a useful resource to realize quantum information, quantum teleportation, quantum crypt...

Cross-field particle transport increases sharply with distance into the scrape-off layer and plays a dominant role in the ‘main-chamber recycling’ regime in Alcator C-Mod, a regime where most of the plasma particle efflux recycles on the main-chamber walls rather than flows into the divertor volume. This observation has potentially important implications for a reactor: Contrary to the ideal pic...

[1] For hillslopes undergoing ‘‘diffusive’’ soil transport, it is often assumed that the soil flux is proportional to the local land-surface gradient, where the coefficient of proportionality is like a diffusion coefficient. Inasmuch as transport involves quasirandom soil particle motions related to biomechanical mixing and similar dilational processes, a slope-dependent relation arises from a ...

Particle deposition/erosion can affect mirrors used in plasma diagnostics and this is a major concern for future fusion reactors. This subject is analyzed for the first and second mirrors of the proposed Motional Stark Effect edge plasma current diagnostic for ITER. Particle fluxes to the diagnostic module aperture are given by edge-plasma/impurity-transport solutions for convective plasma flow...

A combined IR and visible camera system [G. A. Wurden et al., "A high resolution IR/visible imaging system for the W7-X limiter," Rev. Sci. Instrum. (these proceedings)] and a filterscope system [R. J. Colchin et al., Rev. Sci. Instrum. 74, 2068 (2003)] were implemented together to obtain spectroscopic data of limiter and first wall recycling and impurity sources during Wendelstein 7-X startup ...

Particle-size segregation commonly occurs in both wet and dry granular free-surface flows through the combined processes of kinetic sieving and squeeze expulsion. As the granular material is sheared downslope, the particle matrix dilates slightly and small grains tend to percolate down through the gaps, because they are more likely than the large grains to fit into the available space. Larger p...
