Inspired by the phase diagram of the cuprate oxide family of high temperature superconductors, the focus of our research in recent years has been unconventional superconductivity exhibited by correlated metals. In particular, we devoted attention to the investigation of the Fe-based superconductors (FeSCs), materials for which the formation of the high-temperature superconducting state (H…
Over the past two years, our group developed a research program based on X-ray spectroscopy of quantum materials [1,2,3]. It is the purpose of this project to provide continuous financial support to the activities of our group during the next 2 years. We propose a research program based upon , but not restricted to, the availability of the state of the art facilities of the forthcoming EM…
The term "Fe-based superconductors" (FeSCs) denotes a large family of electronically correlated materials associated with a rich phenomenology of diverse electronic phases. These include unconventional and high temperature superconductors, but also magnetic phases and the so-called electronic nematic phase. Essential to understanding this rich phenomenology is the study of the electronic …
Motivated by the rich phenomenology, defined by the observation of diverse electronic phases, found in materials of the family of Fe-based superconductors (FeSCs), we propose in this work the exploration of the phase diagram for ternary alloys based on Y-Fe-Ge. The starting point of our exploration are the FeSCs YFe2Ge2. Initially considered as materials for which superconductivity (SC) w…
Resonant inelastic X-ray scattering (RIXS) is a specific technique for investigating the electronic structure of solid-state systems. RIXS also allows the observation of collective properties of electronic excitations, such as collective spin excitations (magnons and paramagnons) and charge excitations (such as particle-hole excitations). In the context of iron-based superconductors (FeSC…
The determination of the energy scale of the magnetic interactions is an important step in the study of frustrated magnets. The usual approach to this problem is to fit the system's magnetic susceptibility to the Curie-Weiss law. The fitting renders the Curie-Weiss constant which, in turn, can be connected to the exchange interaction between localized spins in the solid. For solids hostin…
In this project, we propose an investigation by specialized X-ray based techniques of the charge density wave (CDW) order in the novel transition metal dichalcogenide ZrTe_{2}. When doped with Ni (Ni_{x}ZrTe_{2}), it is suggested by transport measurements that this novel material undergoes a CDW transition with a transition temperature (T) of about T_{\text{CDW}}=285 K. This same material…
Iron Based Superconductors (IBS) are an interesting family of magnetic materials in which high temperature superconductivity appears. The understanding of the superconductor transition so far, relates this phase with magnetic fluctuations in the material: under the effect of electron or whole doping, the magnetic order is suppressed and the superconductivity emerges. To characterize the m…

Iron-based superconductors (FeSC) are an interesting family of materials in which high-temperature superconductivity appears. The understanding of the superconducting transition so far relates this phase with magnetic fluctuations in the system. Indeed, under the effect of electron or hole doping, magnetic order is suppressed and superconductivity emerges. Due to the itinerant behavior of…
X rays scattering close to the resonant condition provides element sensitivity and accurate structural information of solid state systems. In principle, the inelastic component of the scattering contains valuable information about the many elementary excitations in the solid under investigation. Current developments of beam line technologies made possible these studies employing synchrotr…
