Massive type 0A string theory and M-theory
Niccolò Cribiori, Andriana Makridou, Salvatore Raucci
We propose an M-theory origin for the two massive deformations of type 0A string theory by extending Hull's realization of massive type IIA in the context of a recent proposal for…
Sharpened Dynamical Cobordism
Andriana Makridou, Alejandro Javier Puga Gómez
We propose a sharpened version of Dynamical Cobordism, where the physical structure of the theory in question determines an allowed range for the critical exponent . W…
Intersecting End of the World Branes
Roberta Angius, Andriana Makridou, Angel M. Uranga
Dynamical cobordisms implement the swampland cobordism conjecture in the framework of effective field theory, realizing codimension 1 end of the world (ETW) branes as singularities…
Dimensional Reduction of Cobordism and K-theory
Ralph Blumenhagen, Niccolò Cribiori, Christian Kneissl +1
It has been proposed that cobordism and K-theory groups, which can be mathematically related in certain cases, are physically associated to generalised higher-form symmetries. As a…
The Dark Dimension in a Warped Throat
Ralph Blumenhagen, Max Brinkmann, Andriana Makridou
By combining swampland conjectures with observational data, it was suggested that our universe should lie in an asymptotic region of the quantum gravity landscape. The generalized…
Dynamical Cobordism of a Domain Wall and its Companion Defect 7-brane
Ralph Blumenhagen, Niccolò Cribiori, Christian Kneissl +1
Starting from an already known solution in the literature, we study the dynamical cobordism induced by the backreaction of a non-supersymmetric, positive tension domain wall in str…
Swampland Conjectures for an Almost Topological Gravity Theory
Rafael Álvarez-García, Ralph Blumenhagen, Christian Kneissl +2
We analyze AdS and dS swampland conjectures in a three-dimensional higher spin theory with self-interacting matter, which contains conformal gravity and is almost topological. A th…
De Sitter Quantum Breaking, Swampland Conjectures and Thermal Strings
Ralph Blumenhagen, Christian Kneissl, Andriana Makridou
We argue that under certain assumptions the quantum break time approach and the trans-Planckian censorship conjecture both lead to de Sitter swampland constraints of the same funct…
KKLT and the Swampland Conjectures
Ralph Blumenhagen, Max Brinkmann, Daniel Klaewer +2
Recently, various swampland conjectures have been proposed that every UV complete effective field theory should satisfy. In particular, these deal with the properties of AdS and dS…
dS Spaces and Brane Worlds in Exotic String Theories
Ralph Blumenhagen, Max Brinkmann, Andriana Makridou +2
We investigate string-phenomenological questions of Hull's exotic superstring theories with Euclidean strings/branes and multiple times. These are known to be plagued by pathologie…
Quantum Log-Corrections to Swampland Conjectures
Ralph Blumenhagen, Max Brinkmann, Andriana Makridou
Taking the anti-de Sitter minimum of KKLT and the large volume scenario at face value, we argue for the existence of logarithmic quantum corrections to AdS swampland conjectures. I…
A Note on the dS Swampland Conjecture, Non-BPS branes and K-theory
Ralph Blumenhagen, Max Brinkmann, Andriana Makridou
We point out that the de Sitter swampland conjecture would be falsified if classical fluxed Type IIA orientifold vacua with a single non-BPS D7-brane were indeed part of the string…
