We study the double scaling limit of the O(N)-invariant tensor model, initially introduced in Carrozza and Tanasa, Lett. Math. Phys. (2016). This model has an interacting part containing two types of quartic invariants, the tetrahedric and the pillow one. For the 2-point function, we rewrite the sum over Feynman graphs at each order in the 1/N expansion as a finite sum, where the summand is a function of the generating series of melons and chains (a.k.a. ladders). The graphs which are the most… Expand

O(N) Random Tensor Models
We define in this paper a class of three-index tensor models, endowed with $${O(N)^{\otimes 3}}$$O(N)⊗3 invariance (N being the size of the tensor). This allows to generate, via the usual QFTExpand
The double scaling limit of the multi-orientable tensor model
In this paper we study the double scaling limit of the multi-orientable tensor model. We prove that, contrary to the case of matrix models but similarly to the case of invariant tensor models, theExpand
Critical behavior of colored tensor models in the large N limit
Colored tensor models have been recently shown to admit a large N expansion, whose leading order encodes a sum over a class of colored triangulations of the D-sphere. The present paper investigatesExpand
Diagrammatics of the quarticO(N)3-invariant Sachdev-Ye-Kitaev-like tensor model
Various tensor models have been recently shown to have the same properties as the celebrated Sachdev-Ye-Kitaev (SYK) model. In this paper we study in detail the diagrammatics of two such SYK-likeExpand
Large N limit of irreducible tensor models: O(N) rank-3 tensors with mixed permutation symmetry
A bstractIt has recently been proven that in rank three tensor models, the antisymmetric and symmetric traceless sectors both support a large N expansion dominated by melon diagrams [1]. We show howExpand
Uncolored random tensors, melon diagrams, and the Sachdev-Ye-Kitaev models
Certain models with rank-$3$ tensor degrees of freedom have been shown by Gurau and collaborators to possess a novel large $N$ limit, where $g^2 N^3$ is held fixed. In this limit the perturbativeExpand
Diagrammatics of a colored SYK model and of an SYK-like tensor model, leading and next-to-leading orders
The Sachdev-Ye-Kitaev (SYK) model is a model of q interacting fermions. Gross and Rosenhaus have proposed a generalization of the SYK model which involves fermions with different flavors. In terms ofExpand
Scaling violation in a field theory of closed strings in one physical dimension
Abstract A one dimensional field theory of closed strings is solved exactly in a special double scaling limit, in which the string coupling 1/N goes to zero, the cosmological constant λ approches aExpand
SYK-like tensor quantum mechanics with Sp(N) symmetry
Abstract We introduce a family of tensor quantum-mechanical models based on irreducible rank-3 representations of Sp ( N ) . In contrast to irreducible tensor models with O ( N ) symmetry, theExpand
The 1/N Expansion of Multi-Orientable Random Tensor Models
Multi-orientable group field theory (GFT) was introduced in Tanasa (J Phys A 45:165401, 2012), as a quantum field theoretical simplification of GFT, which retains a larger class of tensor graphs thanExpand
