Query: The World-Line Quantum Mechanics Model at Finite Temperature which is
  Dual to the Static Patch Observer in de Sitter Space   A simple conformal quantum mechanics model of a d-component variable is
proposed, which exactly reproduces the retarded Green functions and conformal
weights of conformally coupled scalar fields in de Sitter spacetime seen by a
static patch observer. It is found that the action integral of this model is
automatically expressed by a complex integral over the time variable t along a
closed contour in a way which is typical to the Schwinger-Keldysh formalism of
a thermofield theory. Hence this model is at finite temperature. The case of
conformally coupled scalar fields in 3d Schwarzschild de Sitter space is also
considered and then a large-N matrix model is obtained.
