Hexadecapole equilibrium distortions of nuclei

Hexadecapole Approximation in Planetary Microlensing

The frequency of microlensing planet detections, particularly in difficult-tomodel high-magnification events, is increasing. Their analysis can require tens of thousands of processor hours or more, primarily because of the high density and high precision of measurements whose modeling requires time-consuming finitesource calculations. I show that a large fraction of these measurements, those th...

How sensitive are equilibrium pricing models to real-world distortions?

In both finance and economics, quantitative models are usually studied as isolated mathematical objects — most often defined by very strong simplifying assumptions concerning rationality, efficiency and the existence of disequilibrium adjustment mechanisms. This raises the important question of how sensitive such models might be to real-world effects that violate the

Computing Equilibrium Prices in Exchange Economies with Tax Distortions

We consider the computation of equilibrium prices in market settings where purchases of goods are subject to taxation. While this scenario is the standard one in applied computational work, so far it has not been an object of study in theoretical computer science. Taxes introduce significant distortions: equilibria are no longer Pareto optimal, sufficient conditions for uniqueness do not contin...

Electronic quadrupole and hexadecapole moment of Ni II ground state

We obtain the electronic quadrupole and hexadecapole moments of the Ni II ground state to be -0.493 au and 0.204 au using relativistic configuration interaction methodology. These results are in good agreement with available experimental results. Apparently this is the first time an electronic hexadecapole moment has been calculated for an atom.
