6d Supergravity Blocks
Yuta Hamada, Seongmin Jeon, Hee-Cheol Kim
We propose a systematic framework for constructing six-dimensional supergravity theories with eight supercharges that respect all known consistency constraints, including anomaly c…
Rethinking quantum information in gravity and fields
Kanato Goto, Yuta Hamada, Kohtaro Kato +6
This paper presents a curated selection of research questions at the intersection of quantum gravity and quantum information, chosen to highlight issues that we regard as particula…
Inflation models selected by the swampland distance conjecture with the Lyth bound
Yuma S. Furuta, Yuta Hamada, Kazunori Kohri
We investigate the extent to which the Swampland Conjecture can be employed to constrain large-field inflationary models from the perspective of quantum gravity consistency. In par…
A finite 6d supergravity landscape from anomalies
Yuta Hamada, Gregory J. Loges
6d supergravities with non-abelian gauge group are subject to many consistency conditions. While the absence of local gauge and gravitational anomalies allows for infinitely many m…
