4 Thermal entanglement of spins in a nonuniform magnetic field

We study the effect of nonuniformities in the magnetic field on the thermal entanglement of a two spin system. We show that in the ferromagnetic case a very small nonuniformity is capable to produce large values of thermal entanglement. In the antiferromagnetic case, nonuniformity only slightly raises the threshold temperature, but lowers the value of entanglement.

Magnetic switching and thermal enhancement of quantum transport through nanowires.

Early investigations of ballistic electronic transport through microconstrictions led to the discovery of conductance quantization. Initially this phenomenon was observed in two-dimensional semiconducting structures, manifesting itself in 2e/h steplike variations of the conductance as a function of the transverse size of the narrowing ~see review in Ref. 1!. Underlying the phenomenon is the dis...

High-Throughput Top-Down Fabrication of Uniform Magnetic Particles

Ion Beam Aperture Array Lithography was applied to top-down fabrication of large dense (10(8)-10(9) particles/cm(2)) arrays of uniform micron-scale particles at rates hundreds of times faster than electron beam lithography. In this process, a large array of helium ion beamlets is formed when a stencil mask containing an array of circular openings is illuminated by a broad beam of energetic (5-8...
