Possible Anderson localization in a holographic superconductor
Hua Bi Zeng
We study the effect of disorder in a holographic superconductor by introducing a quasi-periodic chemical potential. When the condensation of the superconductor is sufficiently smal…
A thermal quench induces spatial inhomogeneities in a holographic superconductor
Antonio M. García-García, Hua Bi Zeng, Hai Qing Zhang
Holographic duality is a powerful tool to investigate the far-from equilibrium dynamics of superfluids and other phases of quantum matter. For technical reasons it is usually assum…
A holographic model of SQUID
Rong-Gen Cai, Yong-Qiang Wang, Hai-Qing Zhang
We construct a holographic model of superconducting quantum interference device (SQUID) in the Einstein-Maxwell-complex scalar theory with a negative cosmological constant. The SQU…
Mimic the optical conductivity in disordered solids via gauge/gravity duality
Jia-Rui Sun, Shang-Yu Wu, Hai-Qing Zhang
We study the optical conductivity in a (2+1)-dimensional non-relativistic field theory holographically dual to a (3+1)-dimensional charged Lifshitz black brane with the Einstein-Ma…
Deconfinement transition and Black Holes
Antonino Flachi
In this paper we propose an effective description of the transition to deconfinement in the vicinity of a black hole. For this we adapt the approach that uses the dual quark conden…
Charged black rings from inverse scattering
Jorge V. Rocha, Maria J. Rodriguez, Oscar Varela +1
The inverse scattering method of Belinsky and Zakharov is a powerful method to construct solutions of vacuum Einstein equations. In particular, in five dimensions this method has b…

Mariano Cadoni, Paolo Pani, Matteo Serra
We investigate the infrared behavior of the spectrum of scalar-dressed, asymptotically Anti de Sitter (AdS) black brane (BB) solutions of effective holographic models. These soluti…

Antonino Flachi
In this paper we compute the effective action at finite temperature and density for the dual fermion condensate in curved space with the fermions described by an effective field th…
Strongly Interacting Fermions and Phases of the Casimir Effect
Antonino Flachi
With the intent of exploring how the interplay between boundary effects and chiral symmetry breaking may alter the thermodynamical behavior of a system of strongly interacting ferm…
Novel Features of the Transport Coefficients in Lifshitz Black Branes
Jia-Rui Sun, Shang-Yu Wu, Hai-Qing Zhang
We study the transport coefficients, including the conductivities and shear viscosity of the non-relativistic field theory dual to the Lifshitz black brane with multiple U(1) gauge…
Extremal black brane solutions in five-dimensional gauged supergravity
Susanne Barisch-Dick, Gabriel Lopes Cardoso, Michael Haack +1
We study stationary black brane solutions in the context of N = 2, U(1) gauged supergravity in five dimensions. Using the formalism of first-order flow equations, we construct exam…
Interacting Fermions, Boundaries, and Finite Size Effects
Antonino Flachi
In this work we analyze how effects of finite size may modify the thermodynamics of a system of strongly interacting fermions that we model using an effective field theory with fou…
Non-holomorphic deformations of special geometry and their applications
Gabriel Lopes Cardoso, Bernard de Wit, Swapna Mahapatra
The aim of these lecture notes is to give a pedagogical introduction to the subject of non-holomorphic deformations of special geometry. This subject was first introduced in the co…

Jorge V. Rocha, Maria J. Rodriguez, Oscar Varela
We present a new asymptotically flat, doubly spinning black ring of D = 5 Einstein-Maxwell-dilaton theory with Kaluza-Klein dilaton coupling. Besides the mass and two angular momen…

Physics in curved spacetime describes a multitude of phenomena, ranging from astrophysics to high energy physics. The last few years have witnessed further progress on several fron…

Bum-Hoon Lee, Da-Wei Pang, Chanyong Park
We give a review on our recent work arXiv:1006.0779 [hep-th] and arXiv:1006.1719 [hep-th], in which properties of holographic strange metals were investigated. The background is ch…

We study the DC conductivities of various holographic models using the open string metric (OSM), which is an effective metric geometrizing density and electromagnetic field effect.…

We study static black brane solutions in the context of N = 2 U(1) gauged supergravity in four dimensions. Using the formalism of first-order flow equations, we construct novel ext…
Holographic charge transport in Lifshitz black hole backgrounds
José P. S. Lemos, Da-Wei Pang
We study charge transport properties in a domain-wall geometry, whose near horizon IR geometry is a Lifshitz black hole and whose UV geometry is AdS. The action for the gauge field…

Rong-Gen Cai, Da-Wei Pang
We investigate several holographic properties of charged black holes with corrections, which originate from Kaluza-Klein reductions of five-dimensional Gauss-Bonnet gravit…
