An equivalence in random matrix and tensor models via a dually weighted intermediate field representation
Juan Abranches, Alicia Castro, Reiko Toriumi
We present novel equivalences in random matrix and tensor models between complex and self-adjoint theories with nontrivial quadratic terms in the action, established through an int…

Dually weighted multi-matrix models as a path to causal gravity-matter systems
Juan L. A. Abranches, Antonio D. Pereira, Reiko Toriumi
We introduce a dually-weighted multi-matrix model that for a suitable choice of weights reproduce two-dimensional Causal Dynamical Triangulations (CDT) coupled to the Ising model.…
