Dynamical Triangulations for 2D Pure Gravity and Topological Recursion
Hiroyuki Fuji, Masahide Manabe, Yoshiyuki Watabiki
We show that, in two-dimensional Euclidean quantum gravity without matter fields, the Schwinger-Dyson equations derived within the Hamiltonian framework of non-critical string fiel…

Can a late-time cosmological model based on baby universe absorption explain the z-variation of w?
Jan Ambjorn, Yoshiyuki Watabiki
We point out that a simple late-time cosmological model where our Universe can absorb "baby universes" explains the exponential expansion of our universe without the need of a cosm…

The emergence of the universe
Jan Ambjorn, Yoshiyuki Watabiki
We show how our Universe can emerge from a symmetry breaking of a multicomponent algebra, where the components in addition form a Jordan algebra. We discuss how symmetry brea…
