Theoretical modelling of superconducting nickelates: effects of doping from atomic substitution, disorder and dimensionality effects, computation of physical observables, Fermi surface reconstructions and instabilities.

(more details in the attached pdf file)

This PhD-work is not an ab initio calculation but it is a model Hamiltonian phenomenological approach taking into acount disorder and strong electronic correlation effects in the framework of the dynamical Mean Field Theory (DMFT). A focus is put onto developping and using a DMFT method to study the effects of doping by atomic substitution of strongly correlated atoms. Some knowledge in band structure calculations may be appreciated but it is not mandatory.

This theoretical work is part of the project SUPERNICKEL granted by the french national research agency (ANR).
