Low order maximally single-trace graphs as the first counterexamples to large N factorization in random tensors
Jonathan Berthold, Hannes Keppler
We give the first and lowest order examples of 3-regular 3-edge-colored graphs that demonstrate the non-factorization of tensor model invariants in the large limit of Gaussian…

Duality of O(N) and Sp(N) random tensor models: tensors with symmetries
H. Keppler, T. Krajewski, T. Muller +1
In a recent series of papers, a duality between orthogonal and symplectic random tensor models has been proven, first for quartic models and then for models with interactions of ar…
