The Phenomenology of the Dark Dimension and Non-Supersymmetric Strings
Cumrun Vafa
Swampland principles, combined with the smallness of dark energy , lead to the dark dimension scenario, with one extra dimension of micron size. We review this scenario and its…
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…
On BPS Branes
Cumrun Vafa, David H. Wu, Kai Xu
We study supersymmetric BPS branes (BPS-B) in supergravity theories. Some of these states are anticipated by BPS black-brane (BPS-BB) solutions of supergravity. In particular, we d…
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…
