In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a partic...
Comment on ‘‘Particle dispersal due to interplay of motions in the surface layer of a small reservoir’’ (by P. Okely, J. Imberger, and K. Shimizu) and ‘‘Processes affecting horizontal mixing and dispersion in Winam Gulf, Lake Victoria’’ (by P. Okely, J. Imberger, and J. P. Antenucci)
Particle dispersal surface layer of a small reservoir

Okely et al. (2010a,b) are concerned with horizontal
dispersion and mixing in lakes and employ numerical
modeling to estimate horizontal dispersion coefficients. In
both papers, the dispersal of fo...
Nitrogen dilution effect for small angle GDH experiment in JLab Hall-A
GDH sum rule dilution factor correction cross section asymmetry
2009/8/14
In the GDH sum rule measurement in JLab Hall-A, to obtain the cross section of electron scattering on polarized 3He and its asymmetry in different helicity states, the dilution effect from unpolarized...
Uniqueness of smooth stationary black holes in vacuum: small perturbations of Kerr
Kerr smooth stationary black holes in vacuum
2014/4/3
In collaboration with S. Alexakis and A. Ionescu we show that smooth, asymptotically flat, non-degenerate solutions of the Einstein vacuum equations, which are suuficiently close to a Kerr solution, i...
