Electronic spin and orbital (dd) excitation spectra of (CaxLa1−x )(Ba1.75−xLa0.25+x)Cu3Oy samples are measured by resonant inelastic x-ray scattering (RIXS). In this compound, Tc of samples with identical hole dopings is strongly affected by the Ca/Ba subs ...
Understanding the role of electron correlations in strong spin-orbit transition-metal oxides is key to the realization of numerous exotic phases including spin-orbit–assisted Mott insulators, correlated topological solids, and prospective new high-temperat ...
New advances in X-ray diffraction, extended X-ray absorption fine structure (EXAFS), and X-ray absorption near edge structure (XANES) using synchrotron radiation have now provided compelling evidence for a short-range charge density wave phase (CDW) called ...
The semimetallic, two-dimensional layered transition metal dichalcogenide WTe2 has raised considerable interest due to its huge, non-saturating magnetoresistance. While for the origin of this effect, a close-toideal balance of electrons and holes has been ...
We investigated the ferroelectric perovskite material BaTiO3 by resonant inelastic x-ray scattering (RIXS) at the Ti L-3 edge. We observe with decreasing temperature a transfer of spectral weight from the elastic to the charge-transfer spectral features, i ...
In this thesis, angular resolved photoemission spectroscopy (ARPES) is used to study the electronic structure of different two-dimensional electron systems (2DES). This technique is very surface sensitive and the most direct method to probe the surface ban ...
It has recently been established that the high-transition-temperature (high-T-c) superconducting state coexists with short-range charge-density-wave order(1-11) and quenched disorder(12,13) arising from dopants and strain(14-17). This complex, multiscale p ...
This thesis deals with femtosecond broadband spectroscopy in the visible regime, which is used to study strongly correlated electron systems. The materials that were studied are high-temperature cuprate superconductors of various dopings and the charge-den ...
Vanadium sesquioxide V2O3 is considered a textbook example of Mott-Hubbard physics. In this paper, we present an extended optical study of its whole temperature/doping phase diagram as obtained by doping the pure material with M = Cr or Ti atoms (V1-x M-x) ...
