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…

Coupling renormalization flow in the strongly interacting regime of an asymptotically free quantum field theory in four dimensions
Jürgen Berges, Razvan Gurau, Hannes Keppler +1
We consider a scalar quantum field theory with global symmetry in four Euclidean dimensions and solve it numerically in closed form in the large-N limit. For imaginary tet…

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…
