This PhD project aims at applying innovative mathematical tools coming

from optimal control theory to improve theoretical and experimental techniques

in Nuclear Magnetic Resonance (NMR), in Electron Spin Resonance (ESR) and in NV

centers. This approach will allow us to explore and to experimentally reach the

physical limits of the corresponding spin dynamics in presence of typical

experimental imperfections and limitations. A first objective will be to

develop new optimal control algorithms able for an inhomogeneous ensemble of

spins to maximize the signal to noise ratio per unit time of the system. A

general problem is to generalize the Ernst angle solution used in NMR, which is

only valid for a homogeneous spin ensemble. This work will be done in

collaboration with the group of S. Glaser (TUM, Munich, Germany). This approach

will find different applications in NMR and ESR where the sensitivity of the

experiment is a crucial parameter. The student will focus on a specific

experimental setup in ESR used by the group of P. Bertet (CEA, Paris Saclay),

where an important goal is the maximization of the emitted signal of spins

coupled to a microwave resonator. The student will take into account in the

numerical computation specific constraints of this experimental setup. In the

same direction, the student will also use optimal control techniques to design

new CMPG sequences accounting for the coupling between the spins and the

cavity. The same types of control techniques will also be used for manipulating

NV ensembles in collaboration with the group of T. Debuisschert (Thalès,

Paris). This will allow the improvement of the sensitivity of the corresponding

experiments. For a more fundamental point of view, the ESR will investigate the

numerical techniques used to design robust control fields with respect to

experimental imperfections. A first objective will be to understand the

efficiency of these methods and to prove the optimality (this concept will be

to define rigorously) of the control fields. The ESR will mainly study spin

systems but it is clear that the results of this project will not be restricted

to the physical systems investigated and the techniques developed during the

PhD could be applied to other physical systems with similar properties.
