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…
Zp charged branes in flux compactifications
Mikel Berasaluce-González, Pablo G. Cámara, Fernando Marchesano +1
We consider 4d string compactifications in the presence of fluxes, and classify particles, strings and domain walls arising from wrapped branes which have charges conserved modulo…
Global Supersymmetry on Curved Spaces in Various Dimensions
A. Kehagias, J. G. Russo
We propose methods towards a systematic determination of d dimensional curved spaces where Euclidean field theories with rigid supersymmetry can be defined. The analysis is carried…
Higgs-Dilaton Lagrangian from Spectral Regularization
M. A. Kurkov, Fedele Lizzi
In this letter we calculate the full Higgs-Dilaton action describing the Weyl anomaly using the bosonic spectral action. This completes the work we started in our previous paper (J…
Watchers of the multiverse
Jaume Garriga, Alexander Vilenkin
An unresolved question in inflationary cosmology is the assignment of probabilities to different types of events that can occur in the eternally inflating multiverse. We explore th…
Localization of scalar fields on self-gravitating thick branes
Alexander A. Andrianov, Vladimir A. Andrianov, Oleg O. Novikov
The model of a domain wall ("thick" brane) in noncompact five-dimensional space-time is considered with geometries of type generated by self-interacting scalar matter. The…
