On the Fourier transform of the characteristic functions of domains with -smooth boundary
We consider domains with -smooth boundary and
study the following question: when the Fourier transform of the
characteristic function belongs to ?Comment: added two references; added footnotes on pages 6 and 1
Self-assembled Zeeman slower based on spherical permanent magnets
We present a novel type of longitudinal Zeeman slower. The magnetic field
profile is generated by a 3D array of permanent spherical magnets, which are
self-assembled into a stable structure. The simplicity and stability of the
design make it quick to assemble and inexpensive. In addition, as with other
permanent magnet slowers, no electrical current or water cooling is required.
We describe the theory, assembly, and testing of this new design
Critical behavior of --model with antisymmetric tensor order parameter coupled with magnetic field
The critical behavior of --model with antisymmetric tensor
order parameter at charged regime is studied by means of the field theoretic
renormalization group at the leading order of -expansion (one-loop
approximation). It is shown that renormalization group equations have no
infrared attractive charged fixed points. It is also shown that anomalous
dimension of the order parameter in charged regime appears to be gauge
dependent.Comment: 6 pages; the talk presented at 19th International Seminar on High
