Dimer models, integrable systems and quantum Teichmuller space (2011)
Journal Article
Franco, S. (2011). Dimer models, integrable systems and quantum Teichmuller space. Journal of High Energy Physics, 2011(9), Article 57. https://doi.org/10.1007/jhep09%282011%29057

We introduce a correspondence between dimer models (and hence superconformal quivers) and the quantum Teichmüller space of the Riemann surfaces associated to them by mirror symmetry. Via the untwisting map, every brane tiling gives rise to a tiling o... Read More about Dimer models, integrable systems and quantum Teichmuller space.

Gauge theories from D7-branes over vanishing 4-cycles (2011)
Journal Article
Franco, S., & Torroba, G. (2011). Gauge theories from D7-branes over vanishing 4-cycles. Journal of High Energy Physics, 2011(01), Article 17. https://doi.org/10.1007/jhep01%282011%29017

We study quiver gauge theories on D7-branes wrapped over vanishing holomorphic 4-cycles. We investigate how to incorporate O7-planes and/or flavor D7-branes, which are necessary to cancel anomalies. These theories are chiral, preserve four supercharg... Read More about Gauge theories from D7-branes over vanishing 4-cycles.

Phenomenological models of holographic superconductors and Hall currents (2010)
Journal Article
Aprile, F., Franco, S., Rodrıguez-Gomez, D., & Russo, J. G. (2010). Phenomenological models of holographic superconductors and Hall currents. Journal of High Energy Physics, 2010(05), Article 102. https://doi.org/10.1007/jhep05%282010%29102

We study general models of holographic superconductivity parametrized by four arbitrary functions of a neutral scalar field of the bulk theory. The models can accommodate several features of real superconductors, like arbitrary critical temperatures... Read More about Phenomenological models of holographic superconductors and Hall currents.

Single-sector supersymmetry breaking in supersymmetric QCD (2010)
Journal Article
Franco, S., & Kachru, S. (2010). Single-sector supersymmetry breaking in supersymmetric QCD. Physical Review D, Particles and fields, 81(9), Article 095020. https://doi.org/10.1103/physrevd.81.095020

We construct examples of single-sector supersymmetry breaking based on simple deformations of supersymmetric QCD with (weakly) gauged flavor group. These theories are calculable in a weakly coupled Seiberg dual description. In these models, some of t... Read More about Single-sector supersymmetry breaking in supersymmetric QCD.

A general class of holographic superconductors (2010)
Journal Article
Franco, S., García-García, A., & Rodriguez-Gómez, D. (2010). A general class of holographic superconductors. Journal of High Energy Physics, 2010(4), Article 92. https://doi.org/10.1007/jhep04%282010%29092

We introduce a simple generalization of the basic holographic superconductor model in which the spontaneous breaking of a global U(1) symmetry occurs via the Stückelberg mechanism. This more general setting allows tuning features such as the order of... Read More about A general class of holographic superconductors.

Dynamical supersymmetry breaking, with flavor (2010)
Journal Article
Craig, N., Essig, R., Franco, S., Kachru, S., & Torroba, G. (2010). Dynamical supersymmetry breaking, with flavor. Physical Review D, 81(7), Article 075015. https://doi.org/10.1103/physrevd.81.075015

We explore calculable models with low-energy supersymmetry where the flavor hierarchy is generated by quark and lepton compositeness, and where the composites emerge from the same sector that dynamically breaks supersymmetry. The observed pattern of... Read More about Dynamical supersymmetry breaking, with flavor.

Holographic approach to phase transitions (2010)
Journal Article
Franco, S., García-García, A. M., & Rodríguez-Gómez, D. (2010). Holographic approach to phase transitions. Physical Review D, 81(4), Article 041901(R). https://doi.org/10.1103/physrevd.81.041901

We provide a description of phase transitions at finite temperature in strongly coupled field theories using holography. For this purpose, we introduce a general class of gravity duals to superconducting theories that exhibit various types of phase t... Read More about Holographic approach to phase transitions.

Holographic Gauge Mediation (2009)
Journal Article
Benini, F., Dymarsky, A., Franco, S., Kachru, S., Simic, D., & Verlinde, H. (2009). Holographic Gauge Mediation. Journal of High Energy Physics, 2009(12), Article 031. https://doi.org/10.1088/1126-6708/2009/12/031

We discuss gravitational backgrounds where supersymmetry is broken at the end of a warped throat, and the SUSY-breaking is transmitted to the Standard Model via gauginos which live in (part of) the bulk of the throat geometry. We find that the leadin... Read More about Holographic Gauge Mediation.

M2-branes on orbifolds of the cone over Q^{1,1,1} (2009)
Journal Article
Franco, S., Klebanov, I. R., & Rodriguez-Gómez, D. (2009). M2-branes on orbifolds of the cone over Q^{1,1,1}. Journal of High Energy Physics, 2009(08), Article 033. https://doi.org/10.1088/1126-6708/2009/08/033

We study the = 2 supersymmetric Chern-Simons quiver gauge theory recently introduced in arXiv:0809.3237 to describe M2-branes on a cone over the well-known Sasaki-Einstein manifold Q1,1,1. For Chern-Simons levels (k,k,−k,−k) we argue that this theory... Read More about M2-branes on orbifolds of the cone over Q^{1,1,1}.

N-ification of Forces: A Holographic Perspective on D-brane Model Building (2009)
Journal Article

We study geometric aspects of extensions of the supersymmetric standard model that exhibit a periodic duality cascade. Via the holographic correspondence, the growth of the gauge group rank towards the UV is interpreted as a gradual decompactificatio...
