The vulnerability of quantum information to decoherence requires active intervention to prevent logical errors in a functioning quantum computer. This has led to the development of approaches countering noise from a hardware or control perspective th

Studying nuclear structure and nuclear reactions based on the microscopic nuclear forces has been a central topic in nuclear physics since its inception. However, tricky puzzles rooted in conventional microscopic nuclear forces --- for example, the n

The GBAR experiment aims at measuring the free fall of ultra-cold antihydrogens (neV).This implies the production of antihydrogen ions, which are obtained by two charge exchange reactions involving antiprotons and positronium atoms. The goal of this

Dans cette thèse, nous construisons un modèle de liaisons fortes tridimensionnel minimal pour les cuprates supraconducteurs monocouches à base de lanthane. Celui-ci prend en compte huit orbitales, dont deux d'entre elles impliquent les ions oxygè

In this thesis, we construct a minimal three-dimensional tight-binding model for single-layer La-based cuprate superconductors. It entails eight orbitals, two of them involving apical oxygen ions. Parameter optimization allows to almost perfectly rep

This thesis, whose topic is quantum chemistry algorithms, is made in the context of the change in paradigm that has been going on for the last decade, in which the usual sequential algorithms are progressively replaced by parallel equivalents. Indeed

We consider some perturbations of a family of pairwise commuting linear quantum Hamiltonians on the torus with possibly dense pure point spectra. We prove that their Rayleigh–Schrodinger perturbation series converge near each unperturbed eigenvalue
