Towards a quantitative characterization of gravitational universality classes for order-4 random tensor models
Alicia Castro, Astrid Eichhorn, Razvan Gurau
Random tensor models can be used as combinatorial devices to generate Euclidean dynamical triangulations. A physical continuum limit of dynamical triangulations requires a suitable…
The large factorization does not hold for arbitrary multi-trace observables in random tensors
Razvan Gurau, Felix Joos, Benjamin Sudakov
We consider real tensors of order , that is -dimensional arrays of real numbers , where each index can take values. The tensor entries $T_{a^1…
Free cumulants and freeness for unitarily invariant random tensors
Benoit Collins, Razvan Gurau, Luca Lionni
We address the question of the asymptotic description of random tensors that are local-unitary invariant, that is, invariant by conjugation by tensor products of independent unitar…
Addendum: Long-range multi-scalar models at three loops
Dario Benedetti, Razvan Gurau, Sabine Harribey
We correct the computation of one Feynman diagram in the three-loop beta functions for the long-range quartic multi-scalar model, originally presented in (2020 J. Phys. A: Math. Th…
Asymptotic safety meets tensor field theory: towards a new class of gravity-matter systems
Astrid Eichhorn, Razvan Gurau, Zois Gyftopoulos
Combining asymptotically safe quantum gravity with a tensor field theory, we exhibit the first example of a theory with gravity and scalar fields in four dimensions which may reali…
Long-range multi-scalar models at three loops
Dario Benedetti, Razvan Gurau, Sabine Harribey +1
We compute the three-loop beta functions of long-range multi-scalar models with general quartic interactions. The long-range nature of the models is encoded in a kinetic term with…
