Gapped fermions in top-down holographic superconductors

Autor: Oscar Henriksson, Oliver DeWolfe, Steven S. Gubser, Christopher Rosen

We use holography to compute spectral functions of certain fermionic operators in three different finite-density, zero-temperature states of ABJM theory with a broken U(1) symmetry. In each of the three states, dual to previously studied domain wall

Thermal entropy of a quark-antiquark pair above and below deconfinement from a dynamical holographic QCD model

Autor: Subhash Mahapatra, David Dudal

Publikováno v: PHYSICAL REVIEW D

We discuss the entropy carried by a quark-antiquark pair, in particular across the deconfinement transition. We therefore rely on a self-consistent solution to Einstein-Maxwell-dilaton gravity, capable of mimicking essential features of QCD. In parti

Bounds on the local energy density of holographic CFTs from bulk geometry

Autor: Sebastian Fischetti, Toby Wiseman, Andrew Hickling

The stress tensor is a basic local operator in any field theory; in the context of AdS/CFT, it is the operator which is dual to the bulk geometry itself. Here we exploit this feature by using the bulk geometry to place constraints on the local energy

Journal of high energy physics, 2012, Vol.2012(5), pp.122 [Peer Reviewed Journal]

We compute string theoretic black hole solutions having Lifshitz asymptotics with a general dynamical exponent z>1. We start by constructing solutions in a flux compactification of six dimensional supergravity, then uplift them to massive type IIA su

Nonlinear realization of local symmetries of AdS space

Autor: Sherwin T. Love, T. ter Veldhuis, Muneto Nitta, T.E. Clark

Publikováno v: Department of Physics and Astronomy Faculty Publications

Coset methods are used to construct the action describing the dynamics associated with the spontaneous breaking of the local symmetries of AdS_{d+1} space due to the embedding of an AdS_d brane. The resulting action is an SO(2,d) invariant AdS form o
