The yes boundaries wavefunctions of the universe
Batoul Banihashemi, Gauri Batra, Y. T. Albert Law +2
A generic spacetime topology contains timelike boundaries. Making use of two such boundaries, we formulate a microscopic holographic dual that captures cosmological spacetime beyon…

Quantum stress-energy at timelike boundaries: testing a new beyond-CDM parameter with cosmological data
Oliver H. E. Philcox, Eva Silverstein, Gonzalo Torroba
We analyze the basic cosmological effects of a population of timelike boundaries -- a form of nontrivial spacetime topology -- containing a boundary layer of quantum stress energy.…

Timelike-bounded holography from a solvable sector of the deformation
Eva Silverstein, Gonzalo Torroba
Recent research has leveraged the tractability of style deformations to formulate timelike-bounded patches of three-dimensional bulk spacetimes including . This pro…
