RIXS interferometry and the role of disorder in the quantum magnet BaTiIrO
M. Magnaterra, M. Moretti Sala, G. Monaco +8
Motivated by several claims of spin-orbit driven spin-liquid physics in hexagonal BaTiIrO hosting Ir2O9 dimers, we report on resonant inelastic x-ray scattering…
From Hermitian critical to non-Hermitian point-gapped phases
Carlos Ortega-Taberner, Maria Hermanns
Recent years have seen a growing interest in topological phases beyond the standard paradigm of gapped, isolated systems. One recent direction is to explore topological features in…
Quasimolecular electronic structure of the spin-liquid candidate BaInIrO
A. Revelli, M. Moretti Sala, G. Monaco +16
The mixed-valent iridate Ba3InIr2O9 has been discussed as a promising candidate for quantum spin-liquid behavior. The compound exhibits Ir ions in face-sharing IrO6 octahe…
Spin-orbit coupling and crystal-field splitting in Ti-doped Ca2RuO4 studied by ellipsometry
I. Vergara, M. Magnaterra, J. Attig +5
In Ca2RuO4, the competition of spin-orbit coupling and tetragonal crystal field splitting has been discussed controversially for many years. The orbital occupation dep…
Quantization of topological indices in critical chains at low temperatures
Oleksandr Balabanov, Carlos Ortega-Taberner, Maria Hermanns
Various types of topological phenomena at criticality are currently under active research. In this paper we suggest to generalize the known topological quantities to finite tempera…
Polarization and entanglement spectrum in non-hermitian systems
Carlos Ortega-Taberner, Lukas Rødland, Maria Hermanns
The entanglement spectrum is a useful tool to study topological phases of matter, and contains valuable information about the ground state of the system. Here, we study its propert…
