Monopole Supersymmetries and the Biedenharn Operator

The hidden supersymmetry of the monopole found by De Jonghe et al. is generalized to a spin 1 2 particle in the combined field of a Dirac monopole plus a λ 2 /r 2 potential [considered before by D'Hoker and Vinet], and related to the operator introduced by Biedenharn a long time ago in solving the Dirac-Coulomb problem. Explicit solutions are obtained by diagonalizing the Biedenharn operator.

In Appreciation of Lawrence C. Katz, 1956–2005

Larry Katz, the James B. Duke Professor of Neurobiology at Duke University and an Investigator of the Howard Hughes Medical Institute, died on November 25, 2005 from melanoma. He was a pioneer in the analysis of visual system development and a new leader in functional analysis of the olfactory system. Larry’s trademark was the brilliant technological innovation that suddenly made impossible exp...

, Jr . MERCURY IN SEDIMENTS

In recent years, the Coastal Water Research Project has conducted surveys of the distribution of certain trace substances in sediments around the major municipal wastewater outfalls off southern California. Because of high levels of heavy metals found in sediments near Los Angeles County Sanitation Districts outfall system off Whites Point in 1970, detailed surveys of the Palos Verdes shelf wer...
