Dai-Freed anomalies in particle physics
Iñaki García-Etxebarria, Miguel Montero
Anomalies can be elegantly analyzed by means of the Dai-Freed theorem. In this framework it is natural to consider a refinement of traditional anomaly cancellation conditions, whic…
Non-geometric heterotic backgrounds and 6D SCFTs/LSTs
Anamaría Font, Iñaki García-Etxebarria, Dieter Lust +2
We study six-dimensional theories living on defects of non-geometric backgrounds of the and the heterotic strin…
S-duality in orientifold SCFTs
Iñaki García-Etxebarria, Ben Heidenreich
We present a general solution to the problem of determining all S-dual descriptions for a specific (but very rich) class of SCFTs. These SCFTs are indexed by deco…
Closed tachyon solitons in type II string theory
Iñaki García-Etxebarria, Miguel Montero, Angel M. Uranga
Type II theories can be described as the endpoint of closed string tachyon condensation in certain orbifolds of supercritical type 0 theories. In this paper, we study solitons of t…
Special Points of Inflation in Flux Compactifications
Iñaki García-Etxebarria, Thomas W. Grimm, Irene Valenzuela
We study the realisation of axion inflation models in the complex structure moduli spaces of Calabi-Yau threefolds and fourfolds. The axions arise close to special points of these…
Heterotic NS5-branes from closed string tachyon condensation
Iñaki García-Etxebarria, Miguel Montero, Angel Uranga
We show how to construct the familiar heterotic NS5 brane as a topological soliton in a supercritical version of heterotic string theory. Closed string tachyon condensation removes…
D-brane instantons on non-Spin cycles
Per Berglund, Iñaki García-Etxebarria
We show that non-Spin cycles in type IIB Calabi-Yau orientifold compactifications with vanishing B field naturally support orientifold-invariant D-brane instantons. These instanton…
Helical Luttinger Liquids and Three Dimensional Black Holes
Vijay Balasubramanian, Iñaki García-Etxebarria, Finn Larsen +1
Cold interacting fermions in two dimensions form exactly solvable Luttinger liquids, whose characteristic scaling exponents differ from those of conventional Fermi liquids. We use…
Branes and instantons at angles and the F-theory lift of O(1) instantons
Mirjam Cvetič, Iñaki García-Etxebarria, Robert Richter
We discuss the physics of D-branes and D-brane instantons intersecting at angles, focusing on the (non)generation of a superpotential in the worldvolume theory of the branes. This…
D-brane instantons and matrix models
Iñaki García-Etxebarria
We point out that in some situations it is possible to use matrix model techniques a la Dijkgraaf-Vafa to perturbatively compute D-brane instanton effects. This provides an explana…
