Query: Simulating quantum field theory in curved spacetime with quantum
  many-body systems   This paper proposes a new general framework to build a one-to-one
correspondence between quantum field theories in static 1+1 dimensional curved
spacetime and quantum many-body systems. We show that a massless scalar field
in an arbitrary 2-dimensional static spacetime is always equivalent to a
site-dependent bosonic hopping model, while a massless Dirac field is
equivalent to a site-dependent free Hubbard model or a site-dependent isotropic
XY model. A possible experimental realization for such a correspondence in
trapped ions system is suggested. As applications of the analogue gravity
model, we show that they can be used to simulate Hawking radiation of black
hole and to study its entanglement. We also show in the analogue model that
black holes are most chaotic systems and the fastest scramblers in nature. We
also offer a concrete example about how to get some insights about quantum
many-body systems from back hole physics.
