Dynamical Mean-Field Theory and Strongly Correlated Superconductors: Can repulsion favour superconductivity?

The most striking realizations of superconductivity have been uncovered in materials where electron-electron correlations are strong, leading to Mott insulating states. This is an intuitively surprising situation, because superconductivity requires attractive interactions and Mott physics arises from strong repulsion. While … Continue reading

Frustrated magnetism: the $Ca_3Co_2O_6$ paradigm

In solids, magnetic frustration can lead to exotic states of matter. In this sense, $Ca_3Co_2O_6$ is a textbook case showing unprecendent magnetic state coexistence, dynamics and step like magnetization dependence on magnetic field. Our investigation by means of resonant X-ray … Continue reading

Entangled spin-orbital phases in the d$^9$ model

The phase diagram of the spin-orbital (SO) Kugel-Khomskii ($d^9$) model posed a challenging theoretical problem [1], yet it is still unknown [1]. Here we investigate the phase diagrams of the $d^9$ model, depending on Hund’s exchange $J_H$ and the $e_g$ … Continue reading

Disproportionation at high-spin–low-spin transition in LaCoO$_3$

Emergence of the local magnetic moments is one of the typical features of the systems with strong electronic correlations. Common in transition metal oxides at ambient conditions, the local moment formation competes with effects such as band broadening or crystal field … Continue reading

Magneto-optical excitations in systems with frustrated spin and orbital degrees of freedom

Optical spectroscopy is a highly sensitive tool to investigate the elementary excitations in correlated systems with coupled spin, lattice and orbital degrees of freedom. For example, low-lying electronic excitations of electric and magnetic origin in the THz range can provide … Continue reading
