Gauge/gravity duality is a conjectured correspondence between certain strongly
coupled quantum field theories in 3 or 4 space-time dimensions, and theories of
general relativity in higher dimensions. The duality was discovered and originally
developed for systems with relativistic invariance. It has since become clear that the
duality extends to certain non-relativistic systems, thereby paving the way for applications
to condensed matter physics. In particular, the temperature and entropy of
a thermal state in quantum field theory correspond to the Bekenstein-Hawking temperature
and entropy of an associated black hole on the gravity side. An introduction
to the duality will be presented, and applications to quantum criticality and other
emergent phases will be invoked to illustrate the correspondence.
