Öz

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.

Anahtar Kelimeler

DKP Denklemi, Akım Yoğunluğu, Parçacık Yaratma, Spin-1 parçacıklar.
