String Swampland Conjectures in the Light of Supersymmetric Inflation and Supergravity Methods:

The current paradigm of string theory, or more generally, candidates for quantum gravity, provides a rich landscape for effective field theories. In this context, it has been realized that some theories, although consistent in other respects, cannot be consistently combined with quantum gravity. As such, swampland conjectures have been put forward to test the validity of non-perturbative effective quantum gravity candidates and have attracted intense interest in recent years.

Interestingly, studies show that these conjectures cause severe restrictions and contradictions in the standard cosmology and inflationary paradigm that we can use observational data for comparison. Due to the nature of this dilemma, Ph.D. candidate Ömer Güleryüz, who put forth his work to better understand this problem with supergravity methods, was invited to Harvard University for a year to conduct his research within the swampland group and has been continuing these studies for six months now. The work of Ö.G. is also partially supported by TÜBİTAK 2214-A - International Research Fellowship Programme for Ph.D. Students.
