Abstract

In the present work, as a first step, exact solutions of Duffine-Kemmer-Petiau (DKP) equation whichdefines dynamics of massive spin-1 particles has been obtained in the presence of a time-dependentexternal electric field for a Robertson-Walker(RW) type (1+1)-dimensional space-time model. Next,making use of these solutions, particle creation cases have discussed by calculating current densities. Itis concluded that particle production process directly depends on the scale parameter and the strengthof electric field.

Özet

Bu çalışmada, ilk adım olarak, zamana bağlı bir dış elektrik alanın varlığında Robertson-Walker(RW) tipi (1+1)-boyutlu uzay-zaman modeli kullanılarak kütleli spin-1 parçacıklarını dinamiğini betimleyen Duffine-Kemmer-Petiau (DKP) denkleminin tam çözümleri elde edilmiştir. Daha sonra, elde edilen çözümler kullanılarak akım yoğunluğu hesaplanarak parçacık yaratma durumları tartışılmıştır. Parçacık yaratma sürecinin doğrudan ölçek parametresi ve elektrik alanın büyüklüğüne bağlı olduğu sonucuna ulaşılmıştır.
