Time-dependent Casimir-Polder forces and partially dressed states

A time-dependent Casimir-Polder force is shown to arise during the time evolution of a partially dressed two-level atom. The partially dressed atom is obtained by a rapid change of an atomic parameter such as its transition frequency, due to the action of some external agent. The electromagnetic field fluctuations around the atom, averaged over the solid angle for simplicity, are calculated as a function of time, and it is shown that the interaction energy with a second atom yields a dynamical Casimir-Polder potential between the two atoms

Nontropical sprue with secondary hyperparathyroidism

We have presented the case history of a patient with lifelong, classic nontropical sprue which was previously undiagnosed. She developed secondary hyperparathyroidism with extreme osteitis fibrosa cystica. As do some patients with malabsorption, she presented with musculoskeletal rather than gastrointestinal complaints.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44358/1/10620_2005_Article_BF02235078.pd

Vortex circulation and polarity patterns in closely packed cap arrays

We studied curvature-driven modifications to the magnetostatic coupling of vortex circulation and polarity in soft-magnetic closely packed cap arrays. A phase diagram for the magnetic remanent/transition states at room temperature as a function of diameter and thickness was assembled. For specimens with vortex remanent state (40 nm-thick Permalloy on 330 nm spherical nanoparticles), both vortex circulation and polarity were visualized. Intercap coupling upon vortex nucleation leads to the formation of vortex circulation patterns in closely packed arrays. The remanent circulation pattern can be tailored choosing the direction of the applied magnetic field with respect to the symmetry axis of the hexagonal array. An even and random distribution of vortex polarity indicates the absence of any circulation-polarity coupling
