Query: Quantum Virasoro algebra with central charge c=1 on the horizon of a
  2D-Rindler spacetime   Using the holographic machinery built up in a previous work, we show that the
hidden SL(2,R) symmetry of a scalar quantum field propagating in a Rindler
spacetime admits an enlargement in terms of a unitary positive-energy
representation of Virasoro algebra, with central charge c=1, defined in the
Fock representation. The Virasoro algebra of operators gets a manifest
geometrical meaning if referring to the holographically associated QFT on the
horizon: It is nothing but a representation of the algebra of vector fields
defined on the horizon equipped with a point at infinity. All that happens
provided the Virasoro ground energy h vanishes and, in that case, the Rindler
Hamiltonian is associated with a certain Virasoro generator. If a suitable
regularization procedure is employed, for h=1/2, the ground state of that
generator corresponds to thermal states when examined in the Rindler wedge,
taking the expectation value with respect to Rindler time. This state has
inverse temperature 1/(2beta), where beta is the parameter used to define the
initial SL(2,R) unitary representation. (As a consequence the restriction of
Minkowski vacuum to Rindler wedge is obtained by fixing h=1/2 and 2beta=beta_U,
the latter being Unruh's inverse temperature). Finally, under Wick rotation in
Rindler time, the pair of QF theories which are built up on the future and past
horizon defines a proper two-dimensional conformal quantum field theory on a
cylinder.
