About this Research Topic
Resonant inelastic x-ray scattering (RIXS) is a photon-in photon-out probe for exploring materials. In the last decade, it has emerged as an important tool for exploring correlated materials and allows for exploring lattice, spin, dd, charge, etc, degrees of freedom in the quantum materials. After the realization that RIXS allows for single spin-flip excitations in materials, RIXS has gained prominence as a counterpart to inelastic neutron scattering (INS), particularly for investigating quantum magnets. RIXS is known to offer advantages over INS due to large light-matter interaction and, hence, better statistics, albeit with limited resolution. This has allowed RIXS to emerge as a probe for smaller crystal, thin films, therefore, as a tool for exploring magnetism where INS becomes impractical.
Over the years, RIXS has been extensively used as a great tool for the investigation of unconventional superconductors such as cuprates. One of the major discoveries of RIXS has been the observation of paramagnon, understood to be the carriers of superconductivity in cuprates due to larger statics in RIXS. More recently, the superconductivity was reported in the thin film of infinite layer nickelates, an analog of cuprates for which RIXS is an essential characterization tool as these exist only as thin films to date. This further highlights the relevance of RIXS in characterizing unconventional superconductors. RIXS is also an important tool for exploring quantum magnets and offers new opportunities for quantum magnets realized in materials, which can be a host for exotic quantum phenomena such as quantum spin liquids, fractionalization, confinement, etc. RIXS is being used to study a large of strongly correlated materials such as one-dimensional cuprates, iridates, ruthenates, etc., which are a platform for exotic magnetism.
While significant strides have been made in harnessing RIXS as a potent tool for investigating strongly correlated materials, it remains a technique of considerable complexity. RIXS is inherently photon polarization and atomic edge sensitive and reveals a plethora of excitations. This complexity can, at times, pose challenges in interpretation, demanding substantial theoretical inputs to decipher the data. Furthermore, the recent advances in synchrotron facilities are opening new avenues for exploring new materials and isolating novel excitations in the spectroscopic data. Consequently, these developments are paving the way for an enhanced comprehension of strongly correlated materials. They hold the promise of refining existing models and shedding new light on the intricate world of strongly correlated materials, offering fresh perspectives and insights into this captivating field of study.
