QUELLE CONCEPTION DE LA RENORMALISATION DANS LE MÉTIER D’ENSEIGNANT ?
This article explores the tensions between prescribed norms and teachers’ real activity through the analysis of a training program designed to support their adoption of the Narramus method, recently introduced in Geneva’s primary schools.

Matrix product operators, matrix product states, and ab initio density matrix renormalization group algorithms. [PDF]
Current descriptions of the ab initio density matrix renormalization group (DMRG) algorithm use two superficially different languages: an older language of the renormalization group and renormalized operators, and a more recent language of matrix product

Anisotropic tensor renormalization group [PDF]
We propose a new tensor renormalization group algorithm, Anisotropic Tensor Renormalization Group (ATRG), for lattice models in arbitrary dimensions.

Renormalization Method and Mirror Symmetry
This is a brief summary of our works [arXiv:1112.4063, arXiv:1201.4501] on constructing higher genus B-model from perturbative quantization of BCOV theory. We analyze Givental's symplectic loop space formalism in the context of B-model geometry on Calabi-

Time evolution as refining, coarse graining and entangling
We argue that refining, coarse graining and entangling operators can be obtained from time evolution operators. This applies in particular to geometric theories, such as spin foams.

Functional renormalization group approach to zero-dimensional interacting systems
We apply the functional renormalization group method to the calculation of dynamical properties of zero-dimensional interacting quantum systems. As case studies we discuss the anharmonic oscillator and the single impurity Anderson model.

Renormalization of the Sigma-Omega model within the framework of U(1) gauge symmetry
It is shown that the Sigma-Omega model which is widely used in the study of nuclear relativistic many-body problem can exactly be treated as an Abelian massive gauge field theory. The quantization of this theory can perfectly be performed by means of the

Renormalization of mixing angles [PDF]
A bstractWe discuss the renormalization of mixing angles for theories with extended scalar sectors. Motivated by shortcomings of existing schemes for mixing angles, we review existing renormalization schemes and introduce new ones based on on-shell ...

Hard-soft renormalization and the exact renormalization group [PDF]
The Wilsonian exact renormalization group gives a natural framework in which ultraviolet and infrared divergences can be treated separately. In massless QED we introduce, as the only mass parameter, a renormalization scale $ _R > 0$. We prove, using the flow equation technique, that infrared convergence is a necessary consequence of any zero ...
