چکیده

It is shown that the exact Foldy-Wouthuysen transformation for spin-0 particles on spacetimes described by the metrics ds = V dt −W dx, where V = V (x) and W = W (x), only exists if the scalar field is nonminimally coupled to the Ricci scalar field with a coupling constant equal to 1 6 . The nonminimal coupling term, in turn, does not violate the equivalence principle. As an application we obtain the nonrelativistic Foldy-Wouthuysen Hamiltonian concerning the general solution to the linearized field equations of higher-derivative gravity for a static pointlike source in the Teyssandier gauge.

Exact Foldy-Wouthuysen transformation for spin 0- particle in curved space

The exact Foldy-Wouthuysen transformation concerning spin-0 particles is constructed for a wide class of spacetimes described by the static metric ds = V dt −W dx, where V = V (x) and W = W (x). The field equation for the massive scalar field in the curved spacetime is chosen in the form (

On the exact Foldy-Wouthuysen transformation for a Dirac spinor in torsion and other CPT and Lorentz violating backgrounds

We discuss the possibility to perform and use the exact Foldy-Wouthuysen transformation (EFWT) for the Dirac spinor coupled to different CPT and Lorentz violating terms. The classification of such terms is performed, selecting those of them which admit EFWT. For the particular example of an axial vector field, which can be associated with the completely antisymmetric torsion, we construct an ex...

On gravitational interaction of fermions

We discuss some aspects of the gravitational interaction of the relativistic quantum particles with spin 1/2. The exact Foldy-Wouthuysen transformation is constructed for the Dirac particle coupled to the static spacetime metric. The quasirelativistic limit of the theory is then analyzed. Using the analogous method, we obtain the exact Cini-Touschek transformation and discuss the ultra-relativi...

Some Aspects of the Exact Foldy-wouthuysen Transformation for a Dirac Fermion

The Foldy-Wouthuysen transformation (FWT) is used to separate distinct components of relativistic spinor field, e.g. electron and positron. Usually, the FWT is perturbative, but in some cases there is an involution operator and the transformation can be done exactly. We consider some aspects of an exact FWT and show that, even if the theory does not admit an involution operator, one can use the...

The Foldy–Wouthuysen transformation

The Foldy–Wouthuysen transformation of the Dirac Hamiltonian is generally taught as simply a mathematical trick that allows one to obtain a two-component theory in the low-energy limit. It is not often emphasized that the transformed representation is the only one in which one can take a meaningful classical limit , in terms of particles and antiparticles. We briefly review the history and phys...
