We embed a holographic description of a quantum field theory with Galilean conformal
invariance in string theory. The key observation is that such field theories may be realized as …

Building on our earlier work and that of Son, we construct string theory duals of non-
relativistic critical phenomena at finite temperature and density. Concretely, we find black …

We explore the description of bulk causal structure in a dual field theory. We observe that in
the spacetime dual to a spacelike non-commutative field theory, the causal structure in the …

We embed a holographic model of an U (1) charged fluid with Galilean invariance in string
theory and calculate its specific heat capacity and Prandtl number. Such theories are …

The Null Melvin Twist to D4 brane background has been studied and putting in a bunch of
coincident D8 and anti-D8 branes {\it a la} Sakai-Sugimoto model results in a breakdown of …

The AdS/CFT correspondence [1] is a remarkable framework for studying the dynamics of
quantum field theories at strong coupling, in addition to providing an in-principle answer to …

Condensed matter theory is the study of systems at finite density. In this thesis we will
attempt to argue that gauge-gravity dualities can give deep and meaningful insights into the …
