Title: Unitarity and universality in nonrelativistic conformal field theory

Abstract

We relate the notion of unitarity of a ($0+1$)-D conformally ($$SL(2,\mathbf{R})$$) invariant field theory with that of a nonrelativistic conformal (Schrödinger) field theory using the fact that $$SL(2,\mathbf{R})$$ is a subgroup of nonrelativistic conformal (Schrödinger) group. Exploiting $$SL(2,\mathbf{R})$$ unitarity, we derive the unitarity bounds and null conditions for a Schrödinger field theory (for the neutral as well as the charged sector). In noninteger dimensions the theory is shown to be nonunitary. The use of the $$SL(2,\mathbf{R})$$ subgroup opens up the possibility of borrowing results from ($0+1$)-D $$SL(2,\mathbf{R})$$ invariant field theory to explore Schrödinger field theory, in particular, the neutral sector, which has otherwise been unexplored.
