Our PhD student and research assistant, Ömer Güleryüz, has made noteworthy progress in his research, with his findings being accepted for publication in the esteemed Journal of Cosmology and Astroparticle Physics (JCAP). The paper, titled "(Super)Universal Attractors and the de Sitter Vacua in String Landscape," delves into the connection between the de Sitter swampland conjecture and the underlying structure of the effective field theory space, contributing to a deeper understanding of the relationship between string theory and cosmology.

As a visiting researcher and fellow at the Physics Department of Harvard University, Ömer focused on developing an effective field theory for inflation with spontaneously broken supersymmetry. By employing techniques from nilpotent supergravity and the universal attractor mechanism, he demonstrated how various Kähler potentials can generate the same kinetic term without impacting the scalar potential. He also emphasized the importance of linearly coupled nilpotent superfields in inflation, spontaneous SUSY breaking, and obtaining a de Sitter vacuum.

In addition to his publication, Ömer shared the preliminary results of his research through a poster presentation at the 9th Annual Harvard Physics Department Post-Doc/Research Scholar Retreat. His work was supported by the Scientific and Technological Research Council of Turkey (TÜBİTAK) through the 2214-A - International Research Fellowship Programme for PhD Students.
