IR Black Hole Instabilities Trigger Species-Scale Particle Production
Luis A. Anchordoqui, Alek Bedroya, Dieter Lüst +1
We propose a novel UV-IR mechanism in quantum gravity in which black hole instabilities act as a bridge to the most ultraviolet sector of the theory. Specifically, we argue that wh…
String islands, discrete theta angles and the 6D string landscape
Zihni Kaan Baykara, Héctor Parra De Freitas, Houri-Christina Tarazi
The complete classification of the landscape of 6D string vacua remains an open problem. In this work we prove a classification theorem for 6D $\mathcal{N} =…
New Non-Supersymmetric Tachyon-Free Strings
Zihni Kaan Baykara, Houri-Christina Tarazi, Cumrun Vafa
In four decades of string theory research, only a handful of non-supersymmetric tachyon-free strings with only one neutral scalar at tree level were found. We construct new such no…
The Quasicrystalline String Landscape
Zihni Kaan Baykara, Houri-Christina Tarazi, Cumrun Vafa
In this work we investigate a largely unexplored non-geometric corner of the string landscape: the quasicrystalline orbifolds. These exist at special points of the Narain moduli le…
On the String Landscape Without Hypermultiplets
Zihni Kaan Baykara, Yuta Hamada, Houri-Christina Tarazi +1
In this work we study interesting corners of the quantum gravity landscape with 8 supercharges pushing the boundaries of our current understanding. Calabi-Yau threefolds compactifi…
Non-BPS path to the string lamppost
Alek Bedroya, Sanjay Raman, Houri-Christina Tarazi
We provide further motivation for the string lamppost principle in 9d supergravities. Using a blend of ideas which includes Swampland conjectures, finiteness of black hole entropy,…
On The Finiteness of 6d Supergravity Landscape
Houri-Christina Tarazi, Cumrun Vafa
We consider supergravity theories with 8 supercharges in . We show that all the proposed anomaly free theories with unbounded number of massless modes are restricted to a fini…
Swampland Constraints on 5d Supergravity
Sheldon Katz, Hee-Cheol Kim, Houri-Christina Tarazi +1
We propose Swampland constraints on consistent 5-dimensional supergravity theories. We focus on a special class of BPS magnetic monopole strings which arise in gravita…
Four Dimensional SYM and the Swampland
Hee-Cheol Kim, Houri-Christina Tarazi, Cumrun Vafa
We consider supergravity theories with 16 supercharges in Minkowski space with dimensions . We argue that there is an upper bound on the number of massless modes in such theor…
Twisted Circle Compactifications of 6d SCFTs
Lakshya Bhardwaj, Patrick Jefferson, Hee-Cheol Kim +2
We study 6d superconformal field theories (SCFTs) compactified on a circle with arbitrary twists. The theories obtained after compactification, often referred to as 5d Kaluza-Klein…
