We consider a random matrix model with both pairwise and non-pairwise
contracted indices. The partition function of the matrix model is similar to
that appearing in some replicated systems with random tensor couplings, such as
the p-spin spherical...

The canonical tensor model (CTM) is a tensor model in Hamilton formalism and
is studied as a model for gravity in both classical and quantum frameworks. Its
dynamical variables are a canonical conjugate pair of real symmetric
three-index tensors, ...

The canonical tensor model (CTM) is a tensor model proposing a classically
and quantum mechanically consistent model of gravity, formulated as a
first-class constraint system with structural similarities to the ADM formalism
of general relativity....

Recent developments in quantum gravity have shown the Lorentzian treatment to
be a fruitful approach towards the emergence of macroscopic spacetimes. In this
paper, we discuss another related aspect of the Lorentzian treatment: we argue
that colle...

It is shown that classical spaces with geometries emerge on boundaries of
randomly connected tensor networks with appropriately chosen tensors in the
thermodynamic limit. With variation of the tensors, the dimensions of the
spaces can be freely ch...

Tensor models are generalizations of matrix models, and are studied as
discrete models of quantum gravity for arbitrary dimensions. Among them, the
canonical tensor model (CTM for short) is a rank-three tensor model formulated
as a totally constra...

Canonical tensor model (CTM for short below) is a rank-three tensor model
formulated as a totally constrained system in the canonical formalism. In the

We discuss a renormalization procedure for random tensor networks, and show
that the corresponding renormalization-group flow is given by the Hamiltonian
vector flow of the canonical tensor model, which is a discretized model of
quantum gravity. T...

A canonical formalism of the rank-three tensor model with the notion of local

imposing that local Hamiltonians and the so(N) kinematical symmetry of the
tensor model sh...
