dc.description.abstract |
We study the possibility of constructing \ thin-shell wormhole (TSW) in a particular 𝑓����(𝑅����)-gravity model coupled minimally with nonlinear electromagnetic fields. In doing so, first we give a new static spherically symmetric solution of the theory. Then we apply the cut-and-paste method to construct the TSW. As (the third order derivative with respect to 𝑅����) 𝑓����′′′(𝑅����)≠0 we use the specific junction conditions to match the two spacetimes. We find the exact equilibrium radius of the shell from non-black hole solution and show that a linear perturbation leaves the TSW stable.
Keywords: 𝑓����(𝑅����) gravity, thin-shell wormhole, junction conditions, non-linear electrodynamics, stability. |

ÖZ:
Doğrusal olmayan elektromagnetik alanla minimal kuplajlı özel bir 𝑓���(𝑅���) yerçekim alan modelinde İnce Zar Solucen Deliklerı (İZSD) incelenmektedir. Önce yeni bir statik, Küresel simetrık çözüm buluyoruz. Bunu kullanarak kesip- yapıştırma yöntemi ile İZSD tanımlanıyor. Üçüncü derece türev 𝑓���′′′(𝑅���)≠0, durumunda bağlanma değerleri ile iki uzay-zaman birleştiriliyor. Kesin denge durumu yarıçapı etrafında karadelik içermeyen çözüm kullanılarak doğrusal sarsıma kararlı bır İZSD elde ediyoruz.
Anahtar Kelimeler: 𝑓���(𝑅���) yerçekimi, ince-zar solucan deliği, bağlantı şartları, doğrusal olmayan elektrodinamik, kararlılık. |
