Available in PDF, EPUB and Kindle. Book excerpt: One of the key ideas in the condensed matter physics at a low energy scale is to treat an interacting many-body electron system in terms of weakly interacting emergent particles, namely elementary excitations. Resonant inelastic X-ray scattering (RIXS) has emerged as a powerful tool to study elementary excitations, thanks to the exciting instrumentation improvement and the advent of X-ray synchrotron radiation facilities. By tuning the incident X-ray photon energy to the resonance condition of a specific element, RIXS can resonantly enhance the scattering cross section between the incident photon and the elementary excitation in the material, enabling element-specific measurements. In this dissertation, we investigated magnetic excitations in the recently discovered superconducting infinite-layer nickelate thin films. Besides a similar crystal structure, the infinite-layer nickelate is nominally isoelectronic to the high temperature cuprate superconductors. At this early stage, it is important to experimentally study the similarities and differences between cuprates and nickelates, particularly the respective electronic and magnetic structures. Here, by utilizing the high-resolution RIXS, we found that the parent compound of the infinite-layer nickelate is not a charge-transfer material, like cuprates. Instead, it is probably closer to a Mott compound with an additional coupling with rare-earth metallic states. Furthermore, we also found a branch of dispersive magnetic excitations with a bandwidth of approximately 200 meV in the parent compound nickelates. Although these modes are significantly damped, they are reminiscent of the spin-wave of strongly coupled, anti-ferromagnetically aligned spins on a square lattice. Upon doping, the spectral weight and energy decrease slightly, while the modes become overdamped. The dispersion, doping dependence, damping effect of the magnetic excitation, and the added complexity due to the presence of the rare-earth metallic pockets, together with its comparison with the magnetic excitation in cuprates, will be discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the dynamics of many-electron systems is of fundamental importance to all disciplines of condensed matter physics. A very effective access to electron dynamics is offered by inelastic X-ray scattering (IXS) spectroscopy. The double differential scattering cross section for IXS is directly related to the time-dependent two-particle density correlation function, and, for large momentum and energy transfer (Compton limit) to the electron momentum distribution. Moreover, resonant inelastic X-ray scattering (RIXS) enables the study of electron dynamics via electronic excitations in a very selective manner (e.g. selectively spin, crystal momentum, or symmetry), so that other methods are efficaciously complemented. The progress of IXS spectroscopy is intimately related to the growing range of applications of synchrotron radiation. The aim of the book is to provide the growing community of researchers with accounts of experimental methods, instrumentation, and data analysis of IXS, with representative examples of successful applications, and with the theoretical framework for interpretations of the measurements.

This book was released on 2010-06-30 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since 1911, the Solvay Conferences have shaped modern physics. The 24th edition chaired by Bertrand Halperin did not break the tradition. Held in October 2008, it gathered in Brussels many of the leading figures in the “quantum theory of condensed matter”, addressing some of the most profound open problems in the field.The proceedings contain the “rapporteur talks” giving a broad overview with unique insights by distinguished renowned scientists. These lectures cover the five sessions treating: mesoscopic and disordered systems; exotic phases and quantum phase transitions in model systems; experimentally realized correlated-electron materials; quantum Hall systems, and one-dimensional systems; systems of ultra-cold atoms, and advanced computational methods.In the Solvay tradition, the proceedings include also the prepared comments to the rapporteur talks. The discussions among the participants — some of which are quite lively and involving dramatically divergent points of view — have been carefully edited and reproduced in full.

This book was released on 2007 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) The lattice dynamics above T 2were characterized by inelastic x-ray scattering measurements. By analyzing the data in terms of a damped harmonic oscillator response function, we are able to extract the phonon frequency and damping for all observed modes. We find a longitudinal acoustic phonon branch whose damping increases for q-vectors close to the zone boundary, which is also associated with an apparent softening of the frequency. Both of these anharmonic effects increase as T2 is approached, and are consistent with a soft phonon description of the dimerization. The anomalous phonon damping and softening are then analyzed using the Cross & Fisher theory of spin-phonon interaction leading to a spin-Peierls transition. We find that the theory succeeds in describing the data for a narrow temperature range about Tc2, for q near the zone boundary. It does not account for the anharmonic effects observed at high temperatures. Our experimental analysis represents one of the most in-depth quantitative tests of the Cross & Fisher theory to date. In addition our results suggest that TiOCl is a particularly ideal realization of a spin-Peierls system.
