2d TQFT structure of the superconformal indices with outer-automorphism twists

Noppadol Mekareeya, Jaewon Song, Yuji Tachikawa

We study the superconformal indices of 4d theories coming from 6d N=(2,0) theory of type Γon a Riemann surface, with the action of the outer-automorphism σin the trace. We find tha…

New Transport Properties of Anisotropic Holographic Superfluids

Johanna Erdmenger, Daniel Fernandez, Hansjörg Zeller

We complete the analysis of transport phenomena in p-wave superfluids within gauge/gravity duality, using the SU(2) Einstein-Yang-Mills model with backreaction. In particular, we a…

Normal modes and time evolution of a holographic superconductor after a quantum quench

Xin Gao, Antonio M. García-García, Hua Bi Zeng +1

We employ holographic techniques to investigate the dynamics of the order parameter of a strongly coupled superconductor after a perturbation that drives the system out of equilibr…

Anomaly Cancellation And Abelian Gauge Symmetries In F-theory

Mirjam Cvetič, Thomas W. Grimm, Denis Klevers

We study 4D F-theory compactifications on singular Calabi-Yau fourfolds with fluxes. The resulting N=1 effective theories can admit non-Abelian and U(1) gauge groups as well as cha…

Refined Partition Functions for Open Superstrings with 4, 8 and 16 Supercharges

Dieter Lust, Noppadol Mekareeya, Oliver Schlotterer +1

We analyse the perturbative massive open string spectrum of even dimensional superstring compactifications with four, eight and sixteen supercharges. In each of such cases, we focu…

(Non-)commutative closed string on T-dual toroidal backgrounds

David Andriot, Magdalena Larfors, Dieter Lust +1

In this paper we investigate the connection between (non-)geometry and (non-)commutativity of the closed string. To this end, we solve the classical string on three T-dual toroidal…
