Texto completoThis thesis treats different aspects of random tensors. In the first part of the thesis, we study the formulation of random tensors as a quantum field theory called tensor field theory (TFT). In particular we derive the Schwinger-Dyson equations for a tensor field theory with an U(N)-invariant melonic quartic interactions, at any tensor rank. The correlation functions are classified by boundary graphs and we use the Ward-Takahashi identity to derive the complete tower of exact, analytic Schwinger-Dyson equations for correlation functions with connected boundary graph.We then analyse the large N limit of the Schwinger-Dyson equations for rank 3 tensors. We find the appropriate scalings in powers of N for the various terms present in the action. This enable us to solve the closed Schwinger-Dyson equation for the 2-point function of a TFT with only one quartic melonic interaction, in terms of Lambert's W-function, using a perturbative expansion and Lagrange-Bürmann resummation. Higher-point functions are then obtained recursively.In the second part of the thesis, we study the Sachdev-Ye-Kitaev (SYK) model which is closely related to tensor models. The SYK model is a quantum mechanical model of N fermions who interact q at a time and whose coupling constant is a tensor average over a Gaussian distribution. We study the effect of non-Gaussian average over the random couplings in a complex version of the SYK model. Using a Polchinski-like equation and random tensor Gaussian universality, we show that the effect of this non-Gaussian averaging leads to a modification of the variance of the Gaussian distribution of couplings at leading order in N. We then derive the form of the effective action to all orders and perform an explicit computation of the modification of the variance in the case of a quartic perturbation.In the third part of the thesis, we analyse an application of random tensors to non-linear resonant system. Focusing on a typical model similar to the SYK model but with bosons instead of fermions, we perform a Gaussian averaging both for the tensor coupling between modes and for the initial conditions. In the limit when the initial configuration has many modes excited, we compute the variance of the Sobolev norms to characterise how representative the averaged model is of this class of resonant systems

Texto completoThe predictions derived from the Standard Model of particle physics allow to compare theory with experimental mesurements. As the LHC is currently running its third data taking campain, it is of particular interest in the context of LHC physics. This comparison is crucial both in the context of precision measurements, to detect possible deviations from the Standard Model, and for direct searches for new particles. The recent progress in experimental measurements, particularly with Run 3 of the LHC, calls for improvements in theoretical predictions related to rarer and more complex processes. To achieve this goal, increasing the number of perturbative orders taken into account in the calculations is not the only solution. Techniques such as soft gluon threshold resummation allow terms at all orders to be taken into account by exponentiation. This typically reduces the theoretical errors bars and improves the accuracy of the results. In this thesis, we focused on the application of resummation to processes involving QCD corrections at the subdominant order, firstly in the context of exotic lepton production, and secondly in quark top physics

Texto completoMost problems of physics and mechanics lead to partial differential equations. The many methods that exist are relatively low degree. In this thesis, we propose a method of very high degree. Our idea is to increase the order of interpolation function via a perturbation technique to avoid or reduce the difficulties caused by the high cost operations such as integrations. In dimension 1, the proposed technique is close to the P-version finite elements. At a basic level, approximates the solution by a power series of order p. In the case of a linear equation of order 2, the local resolution can build an element of degree, with two degrees of freedom per element. For nonlinear problems, a linearization of the problem by Newton's method is needed. Tests involving linear and nonlinear equations were used to validate the method and show that the technique has a similar convergence in the p-version finite elements. In dimension 2, the problem is discretized through reorganizing polynomials in homogeneous polynomials of degree k. After a definition of variables called principal and secondary combined with a vertical scanning field, the problem becomes a series of 1D problem. A collocation technique allows to take into account the boundary conditions and coupling conditions and determine the solution of the problem. The collocation technique coupled with the least-squares enabled to improve the initial results and has made more robust the perturbation technique

Texto completoIn the first chapter, we define some tensor products and we identify their dual space. Then, we give some properties of Schatten classes. The end of the chapter is dedicated to the study of Bochner spaces valued in the space of operators that can be factorized by a Hilbert space.The second chapter is dedicated to linear Schur multipliers. We characterize bounded multipliers on B(Lp, Lq) when p is less than q and then apply this result to obtain new inclusion relationships among spaces of multipliers.In the third chapter, we characterize, by means of linear Schur multipliers, continuous bilinear Schur multipliers valued in the space of trace class operators. In the fourth chapter, we give several results concerning multiple operator integrals. In particular, we characterize triple operator integrals mapping valued in trace class operators and then we give a necessary and sufficient condition for a triple operator integral to define a completely bounded map on the Haagerup tensor product of compact operators. Finally, the fifth chapter is dedicated to the resolution of Peller's problems. We first study the connection between multiple operator integrals and perturbation theory for functional calculus of selfadjoint operators and we finish with the construction of counter-examples for those problems
