Effective interactions for the nuclear shell model
Various perturbative and non-perturbative many-body techniques are discussed
in this work. Especially, we will focus on the summation of so-called Parquet
diagrams with emphasis on applications to finite nuclei. Here, the subset of
two-body Parquet equations will be discussed. A practical implementation of the
corresponding equations for studies of effective interactions for finite nuclei
is outlined.Comment: 55 pages, latex, to appear in Advances in many-body theory, vol
New criteria to identify spectrum
In this paper we give some new criteria for identifying the components of a
probability measure, in its Lebesgue decomposition. This enables us to give new
criteria to identify spectral types of self-adjoint operators on Hilbert
spaces, especially those of interest.Comment: 10 page
Eating quality of Holstein bull calves fed only grass or purely herbs matches that of concentrate-fed veal calves
Organic meat production from Holstein calves born in dairy herds require that the bull calves are raised outdoor at least 6 months a year, and on large quantities of roughage
in the diet. This study aimed at elucidating if Holstein bull calves fed either purely grass or purely herbs prior to slaughter would differ in meat quality traits, fatty acid composition and sensory profile and if they differed in quality aspects from concentrate-fed veal calves
Dispersive estimates for Schrodinger operators in dimensions one and three
We prove L^1 --> L^\infty estimates for linear Schroedinger equations in
dimensions one and three. The potentials are only required to satisfy some mild
decay assumptions. No regularity on the potentials is assumed.Comment: 20 pages. Corrected typos and improved explanatory remarks at the en
