The microscopic calculations reproduce fairly well the main features observed in those isotopes that include the linear increase with the neutron number of the quadrupole moments of the 11/2- isomers, as well as the parabolic behavior of the mean-square charge radii …

# MFHUB MFHUB is a very small and simple code that performs mean field calculations for the two dimensional Hubbard model on a triangular lattice. It was written as an exercise for the lecture "Computational methods in solid state theory" that I attended during the summer term 2012 at the Goethe University of Frankfurt.

It divides the molecular degrees of freedom in two sets. The positional degrees of freedom of the few segments in the first set are controlled by a MC simulation. For the the degrees of freedom of the remaining segments we solve for the mean field solution. Calculations in REDCap are formatted the same way as Excel, but instead of using the cell names ([A2]+[A3]), the variable names are used ([bpi_q1]+[bpi_q2]). How do I create a calculated field? On the Online Designer page, you would select Calculated Field as the field type. Type the calculation into the Calculation Equation box.

Density-functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure (or nuclear structure) (principally the ground state) of many-body systems, in particular atoms, molecules, and the condensed phases.Using this theory, the properties of a many-electron system can be determined by using

2005-08-22 · Fields can be inserted into your calculations. Often, a function's syntax will indicate where a field should be inserted into the calculation. For example: SUM(expression). Field names should be encompassed by brackets [ ] in a calculation when the field name contains a space or is not unique.

The results can be written to a new attribute field, a virtual field, or they can be used to update values in an existing field.

The identified deficiencies of the NLO and N 2 LO pseudopotentials derived in this work preclude using it within massive calculations that would produce masses and collective spectra across the Segré chart.

We study this numerical accuracy in detail for a specific numerical choice of representation for mean-field equations that can accommodate any kind of symmetry breaking. Method: The method that we use is a particular implementation of three-dimensional mesh calculations. Its numerical accuracy is governed by three main factors: the size of the box in which the nucleus is confined, the way numerical derivatives are calculated, and the distance between the points on the mesh.

The simulation method used provides an opportunity to scrutinize systematically the details of the mean Calculation performed using the mean field approximation. Now, according to the conventional classification of phase transitions , a transition is first-order if the energy is discontinuous with respect to the order parameter ( i.e. , in this case, the temperature), and second-order if the energy is continuous, but its first derivative with Mean Field Approximation Solution: Iterate mean field equations • Converge to a fixed point.

When performing field calculations with a Python expression, Python math rules are in effect. For example, dividing two integer values will always produce an integer output (3 / 2 = 1). To get decimal output. One of the numbers in the operation must be a decimal value: 3.0/2 = 1.5. Use the float function to explicitly convert the value to a float:

For this reason, a good practice is to add a field, calculate values into it, and confirm the calculation is what you wanted. If it is, you can then calculate the original field to equal the added field. Once you confirm the values are correct in the original field, you can delete the field you added. Abstract Nuclear matter and ground state properties for (proton and neutron) semi-closed shell nuclei are described in relativistic mean field theory with coupling constants which depend on the vector density. The parametrization of the density dependence for σ-, ω- and ρ-meson coupling is obtained by fitting to properties of nuclear matter and some finite nuclei.
