SO(3) quadratures in angular-momentum projection

چکیده

While the angular-momentum projection is a common tool for theoretical nuclear structure studies, large amount of computations are required particularly triaxially deformed states. In present work, we clarify conditions exactness quadratures in method. For efficient computation, Lebedev quadrature and spherical $t$-design introduced to projection. The accuracy discussed comparison with conventional Gauss-Legendre trapezoidal quadratures. We found that most among them necessary number sampling points quadrature, which often proportional computation time, reduced by factor 3/2

Angular-momentum Projection of Cranked Symmetry-unrestricted Slater Determinants

We report on development of a new feature of the code HFODD, allowing for the angular-momentum projection of cranked symmetry-unrestricted Slater determinants. After a brief overview of the main theoretical building blocks and formalism, we present several preliminary applications. In particular, we discuss the case of a well-deformed rotational band in Gd, and we show the emergence of uncompen...

Angular Momentum in Chemistry

Noting that current chemical theory is based almost exclusively on electronic energy and spin variables the equal importance of orbital angular momentum is explored in this paper. From its classical definition the angular momentum of electrons in an atom is shown to obey Laplace’s equation, which automatically leads to discrete values in terms of spherical harmonics. This analysis assumes a con...

Angular Momentum in Quantum Mechanics

We begin with a review of the basic concepts involved in the quantum mechanical description of physical systems and the notation we will use in the lectures. The notes in this Section are not intended to provide an introductory course on Quantum Mechanics. They assume the reader has had at least a first course at undergraduate physics level that covers some historical background and reviews the...

Angular momentum in human walking.

Angular momentum is a conserved physical quantity for isolated systems where no external moments act about a body's center of mass (CM). However, in the case of legged locomotion, where the body interacts with the environment (ground reaction forces), there is no a priori reason for this relationship to hold. A key hypothesis in this paper is that angular momentum is highly regulated throughout...
