Spinning particles in vacuum spacetimes of different curvature types

Popis výsledku v původním jazyce

We consider the motion of spinning test particles with nonzero rest mass in the "pole-dipole" approximation, as described by the Mathisson-Papapetrou-Dixon (MPD) equations, and examine its properties in dependence on the spin supplementary condition added to close the system. In order to better understand the spin-curvature interaction, the MPD equation of motion is decomposed in the orthonormal tetrad whose time vector is given by the four-velocity V-mu chosen to fix the spin condition (the "referenceobserver") and the first spatial vector by the corresponding spin s(mu); such projections do not contain the Weyl scalars. 0 and. 4 obtained in the associated Newman-Penrose (NP) null tetrad. One natural option of how to choose the remaining two spatialbasis vectors is shown to follow "intrinsically" whenever V-mu has been chosen; it is realizable if the particle's four-velocity and four-momentum are not parallel. In order to see how the problem depends on the algebraic type of curvatur
