Constraints on spin observables
Nuclear Physics B - Proceedings Supplements, 2008 Positivity constrains the allowed domain for sets of spin observables in exclusive or inclusive reactions. Examples are given for strangeness-echange reactions and photoproduction.Comment: 4 pages, to appear in the Proc. QCD08, MOntpellier, France, July

Spin observables and spin structure functions: inequalities and dynamics [PDF]
Physics Reports, 2008 Model-independent identities and inequalities relating the various spin observables of a reaction are reviewed in a unified formalism, together with their implications for dynamical models, their physical interpretation, and the quantum aspects of the ...

Observables from the spinning eikonal
Journal of High Energy PhysicsWe study the classical dynamics of spinning particles using scattering amplitudes and eikonal exponentiation. We show that observables are determined by a simple algorithm.

Observation of acoustic spin [PDF]
National Science Review, 2019 ABSTRACT Unlike optical waves, acoustic waves in fluids are described by scalar pressure fields, and therefore are considered spinless. Here, we demonstrate experimentally the existence of spin in acoustics. In the interference of two acoustic waves propagating perpendicularly to each other, we observed the spin angular momentum in free ...

Observation of nuclear-spin Seebeck effect [PDF]
Nature Communications, 2021 AbstractThermoelectric effects have been applied to power generators and temperature sensors that convert waste heat into electricity. The effects, however, have been limited to electrons to occur, and inevitably disappear at low temperatures due to electronic entropy quenching.

Observation of the spin Nernst effect [PDF]
Nature Materials, 2017 The observation of the spin Hall effect triggered intense research on pure spin current transport. With the spin Hall effect, the spin Seebeck effect, and the spin Peltier effect already observed, our picture of pure spin current transport is almost complete.

Observation of spin-orbit effects with spin rotation symmetry [PDF]
Nature Communications, 2017 AbstractThe spin–orbit interaction enables interconversion between a charge current and a spin current. It is usually believed that in a nonmagnetic metal (NM) or at a NM/ferromagnetic metal (FM) bilayer interface, the symmetry of spin–orbit effects requires that the spin current, charge current, and spin orientation are all orthogonal to each other ...

Spin observables in hyperon production
Nuclear Physics A, 2000 4(DISTO Collaboration) * The first exclusive measurements of the spin transfer parameter DN N in the reaction fJp -t p[{+Ahas been performed at Saturne with the polarized beam and with the DISTO spectrometer. The results suggest an OBE mechanism dominated by kaon exchange.

Influence of primary fragment excitation energy and spin distributions on fission observables
EPJ Web of Conferences, 2018 Fission observables in the case of 252Cf(sf) are investigated by exploring several models involved in the excitation energy sharing and spin-parity assignment between primary fission fragments.
