Supersymmetric small-field inflation with tribrid superpotentials [PDF]
, 2016 In this thesis, we study supersymmetric models of tribrid inflation and new inflation, both of which can be realized with a tribrid superpotential. In the first part, we focus on tribrid inflation, deriving relations between cosmological observables ...

Preheating in radiatively corrected φ4 inflation with non-minimal coupling in Palatini formulation
Cumhuriyet Science Journal, 2021 We discuss the impact of the preheating stage due to the interaction of the inflaton to fermions in Palatini formulation. In Palatini inflation with large non-minimal coupling, the field is allowed to return to the plateau region during the reheating ...

Gravitational-wave mediated preheating [PDF]
, 2015 We propose a new preheating mechanism through the coupling of the gravitational field to both the inflaton and matter fields, without direct inflaton–matter couplings.

Optimization of Direct Laser Deposition of a Martensitic Steel Powder (Metco 42C) on 42CrMo4 Steel
Metals, 2021 In this study, the deposition of martensitic stainless-steel (Metco 42C) powder on 42CrMo4 structural steel by direct laser deposition (DLD) was investigated. Clads were produced by varying the laser power, scanning speed, feed rate, and preheating.

Journal of Manufacturing and Materials Processing, 2023 A distinctive characteristic of the powder bed fusion with electron beam (PBF-EB) process is the sintering of the powder particles. For certain metallic materials, this is crucial for the success of the subsequent step, the melting, and, generally, the ...
