+
+**Large-coupling strength expansion in DFT and Hartree-Fock adiabatic connections**
+
+In this talk I will review and put into perspective several results on the large-coupling strength expansion of two adiabatic connections (AC) widely used in electronic structure theory. The first one is the density fixed [1] AC of DFT that connects the Kohn-Sham determinant with the physical state. Its large-coupling strength limit defines a multimarginal optimal transport problem [2-4], also known in physics as the strictly-correlated-electrons (SCE) functional [5-7]. The second one is the AC that connects the Hartree-Fock Slater determinant with the physical state and has as small-coupling expansion the Møller-Plesset perturbation theory [8-10]. I will discuss differences and similarities between the two large-coupling strength expansions and their use in improving approximations in quantum chemistry [11-15].

+
+**Ab initio description of doubly open-shell nuclei via a novel multi-reference perturbation theory**
+
+Recent developments in many-body theory and in the modelling of nuclear Hamiltonians have enabled the ab initio description of a considerable fraction of atomic nuclei up to mass $A \sim 100$. In this context, one of the main challenges consists in devising a method that can tackle doubly open-shell systems and at the same time scales gently with mass number. This would allow both to access all systems below $A \sim 100$ and to open up perspectives for extending ab initio calculations to the whole nuclear chart.
+Here I present a recently proposed many-body approach that aims towards this objective. After introducing the formalism based on a multi-reference perturbation theory [1], I will discuss the first numerical applications [2,3] together with considerations on the state of the art and future perspective in ab initio nuclear structure.
