Adiabaticity and emergence of classical space-time in time-dependent matrix theories
classical space-time time-dependent matrix theories
2010/12/23
We discuss the low-curvature regime of time-dependent matrix theories proposed to describe non-perturbative quantum gravity in asymptotically plane-wave space-times. The emergence of near-classical sp...

We explore the superhorizon generation of large fNL of the local form in two eld in
ation.We calculate the two- and three-point observables in a general class of potentials which allow for an analyt...
