The holographic principle states that a theory of gravity can be equally well described as a theory of quantum fields in one dimension lower. Thus, using holography, one can use quantum field theory to learn about gravity and the other way around. In 1986, Brown and Henneaux showed that imposing boundary conditions at infinity in certain 2+1 dimensional spacetimes leads to symmetries that resemble precisely those of certain quantum field theories. More recently, it has been shown that one also obtains very simple symmetries at the horizons of various black holes in 2+1 dimensional spacetimes, leading to a notion of “soft hair” and to very simple expressions for quantities such as the energy and the entropy. We will test the hypothesis that such simple symmetries also arise near the horizon of more general black holes, including in higher dimensions. We are especially interested in Lifshitz and Schrödinger black holes, which appear in holographic duals of non-relativistic field theories and therefore play a role in applications to atomic and condensed matter physics. In addition to shedding light on the nature of the soft hair of black holes, we aim to explore what are the implications of horizon symmetries on holographically dual nonrelativistic field theories.
