Abstract
Remarkable collective effects in Condensed Matter Physics, such as superconductivity and colossal magnetoresistance, among others, occur in transition-metal oxides, where there is frequently a coupling of electronic degrees of freedom (spin, orbital and charge) between themselves and with the crystal lattice. In these cases, not only the electronic and structural ground states, but also the corresponding excitations (phonons, magnons, orbitons) may, in principle, be coupled and have mixed character. In the project we will investigate ground states and excitations in such systems employing Raman spectroscopy, complemented by other techniques such as Resonant Inelastic X-Ray Scattering (RIXS), Neutron Diffraction and Elastic/Inelastic Scattering, X-Ray Absorption (XANES, EXAFS, XLD, XMCD, etc), High-Resolution X-Ray Diffraction, Resonant/Magnetic X-Ray Diffraction, among others, exploring whenever applicable the coupling between the different involved degrees of freedom.
