Induced Fermionic vacuum polarization in dS spacetime with a compactified cosmic string
E. A. F. Bragança, E. R. Bezerra de Mello, A. Mohammadi
We study the fermionic condensate (FC) and the vacuum expectation value (VEV) of the energy-momentum tensor for a massive spinor field in the de Sitter (dS) spacetime including an…

A soliton with a long-range tail
André Amado, Azadeh Mohammadi
We propose an analytically solvable sextic potential model with non-trivial soliton solutions connecting the trivial vacua. The model does not respect parity symmetry, and like $ϕ^…

Quasinormal modes in kink excitations and kink-antikink interactions: a toy model
João G. F. Campos, Azadeh Mohammadi
We study excitations and collisions of kinks in a scalar field theory where the potential has two minima with symmetry. The field potential is designed to create a square wel…
