Earth and Space ScienceThe findings from the Second Earth Orientation Parameters Prediction Comparison Campaign (2nd EOP PCC) suggest that integrating effective angular momentum (EAM) is vital for enhancing the accuracy of polar motion (PM) predictions. Building on Dill et al.

Angular momentum effects in fission [PDF]
Physical Review C, 2021 Background: The role of angular momentum in fission has long been discussed but the observable effects are difficult to quantify.Purpose: We discuss a variety of effects associated with angular momentum in fission and present quantitative illustrations.Methods: We employ the fission simulation model freya, which is well suited for this purpose because ...

Phonon Angular Momentum Hall Effect [PDF]
Nano Letters, 2020 Spin Hall effect is the transverse flow of the electron spin in conductors under external electric field. Similarly, thermal gradient in magnetic insulators can drive a transverse flow of the spin angular momentum of magnons, which provides a thermal alternative for spin manipulation.

Angular momentum and memory effect
Physical Review D, 2023 It is a long-standing problem in general relativity that the notion of angular momentum of an isolated system has supertranslation ambiguity. In this paper, we argue that the ambiguity is essentially because of the gravitational wave memory. When properly subtracting the memory effect of the observer, one can introduce a supertranslation invariant ...

THE EFFECTS OF ANGULAR MOMENTUM ON HALO PROFILES [PDF]
The Astrophysical Journal, 2016 ABSTRACT The near universality of DM halo density profiles provided by N-body simulations proved to be robust against changes in total mass density, power spectrum, and some forms of initial velocity dispersion. Here we study the effects of coherently spinning up an isolated DM-only progenitor on halo structure.

Interannual Variation in Earth’s Rotation Rate and Its Role as a Climate Change Indicator
Atmosphere, 2023 Exploring the relationship between climate phenomena and anomalies in Earth’s rotation during a corresponding period is helpful for constraining the assessment of global change, even for the early warning of climate events. This study selected the latest

The evolutions of the innermost stable circular orbits in dynamical spacetimes
European Physical Journal C: Particles and Fields, 2021 In this paper, we studied the evolutions of the innermost stable circular orbits (ISCOs) in dynamical spacetimes. At first, we reviewed the method to obtain the ISCO in Schwarzschild spacetime by varying its conserved orbital angular momentum.

On the width of the Δ(1232) in NΔ and ΔΔ states [PDF]
EPJ Web of Conferences, 2019 Due to the finite kinetic energy in the intermediate NΔ state the (internal) energy available for mesonic decay is decreased and consequently the effective NΔ width is suppressed in NN scattering. The same can happen also in ΔΔ case.

Shell Effects at High Angular Momentum [PDF]
Physical Review Letters, 1983 Major-shell effects are seen in the unresolved $\ensuremath{\gamma}$-ray spectra coming from high-spin states in the transition region: $^{154}\mathrm{Er}$ to $^{160}\mathrm{Er}$. The angular momentum alignments in the valence shell, which are spread in frequency in the heavier nuclei, are compressed into the low-frequency region in the lighter nuclei ...

Angular Momentum Effects in Michelson–Morley Type Experiments [PDF]
General Relativity and Gravitation, 2002 The effect of the angular momentum density of a gravitational source on the times of flight of light rays in an interferometer is analyzed. The calculation is made imagining that the interferometer is at the equator of the gravity source and, as long as possible, the metric, provided it is stationary and axisymmetric, is not approximated.
