A Type IIB Dualifold
Zihni Kaan Baykara, Cumrun Vafa
We present evidence that ten-dimensional type IIB string theory orbifolded by the duality symmetry at the strong-coupling fixed point defines a consi…
Isolated Critical Points for Scherk-Schwarz Compactifications of M-theory
Zihni Kaan Baykara, Shi Chen, Cumrun Vafa
We consider Scherk-Schwarz compactifications of M-theory (toroidal compactifications with a non-trivial spin structure) in various dimensions and find isolated critical points of t…
A Duality Web for Non-Supersymmetric Strings
Zihni Kaan Baykara, Matilda Delgado, Emilian Dudas +2
Motivated by the recently proposed geometric descriptions of 0A and 0B in M-theory and F-theory, we propose a web of duality among non-supersymmetric strings. In particular we argu…
M-theory on as Type 0A
Zihni Kaan Baykara, Emilian Dudas, Cumrun Vafa
We propose an exotic geometric M-theory dual for the weak coupling Type 0A string: compactification on a sub-Planckian (two circles connected at a point), where stron…
Counting AdS Vacua
Zihni Kaan Baykara, Alessandro Tomasiello, Cumrun Vafa
We study the 'number' of AdS vacua with a UV cut off . It has been proposed that this number is finite. We find evidence that …
Bounds on Discrete Gauge Symmetries in Supergravity
Zihni Kaan Baykara, Markus Dierigl, Hee-Cheol Kim +2
We place bounds on the order of enhanced discrete gauge symmetries that act on massless fields and thus arise at subloci of the moduli space in supergravity theories. We focus on s…
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-Supersymmetric AdS from String Theory
Zihni Kaan Baykara, Daniel Robbins, Savdeep Sethi
We construct non-supersymmetric AdS3 solutions of the O(16)xO(16) heterotic string. Most of the backgrounds have a classical worldsheet definition but are quantum string vacua in t…
Conway Subgroup Symmetric Compactifications Redux
Zihni Kaan Baykara, Jeffrey A. Harvey
We extend the investigation of special toroidal compactifications of heterotic string theory for which the half-BPS states provide representations of subgroups of the Conway group.…
