Duffin-Kemmer-Petiau equation in curved space-time with scalar linear interaction

摘要

We study the covariant Duffin-Kemmer-Petiau (DKP) equation for spin-zero bosons in the spacetime generated by a cosmic string and we examine the linear interaction of a DKP field with gravitational fields produced by topological defects and thus study the influence of topology on this system. We highlight two classes of solutions defined by the product of the deficit angle with the angular velocity of the rotating frame. We solve the covariant form of the DKP equation in an exact analytical manner for nodeless and one-node states by means of an appropriate ansatz.
