We discuss the dc conductivity of holographic theories with translational invariance broken
by a background lattice. We show that the presence of the lattice induces an effective mass …

We discuss new types of instabilities of D= 4 electrically charged AdS-Reissner-Nordström
black branes that involve neutral pseudo-scalars. The instabilities spontaneously break …

A bstract We continue our study of holographic transport in the presence of a background
lattice. We recently found evidence that the presence of a lattice induces a new intermediate …

A bstract We argue that a SO (d) magnetic monopole in an asymptotically AdS space-time is
dual to a d-dimensional strongly coupled system in a solid state. In light of this, it would be …

A bstract We study the holographic field theory dual of a probe SU (2) Yang-Mills field in a
background (4+ 1)-dimensional asymptotically Anti-de Sitter space. We find a new ground …

A bstract We establish the existence of stable and metastable stationary black hole bound
states at finite temperature and chemical potentials in global and planar four-dimensional …

A bstract We study lattice effects in strongly coupled systems of fermions at a finite density
described by a holographic dual consisting of fermions in Anti-de-Sitter space in the …

A bstract We numerically construct asymptotically AdS black brane solutions of D= 4 Einstein-
Maxwell theory coupled to a pseudoscalar. The solutions are holographically dual to d= 3 …

A bstract Within gauge/gravity duality, we study the class of four dimensional CFTs with
chiral anomaly described by Einstein-Maxwell-Chern-Simons theory in five dimensions. In …

A bstract We study doubly-periodic monopoles, also called monopole walls, determining
their spectral data and computing the dimensions of their moduli spaces. Using spectral data …
