Nature of symmetry breaking at the excitonic insulator transition: TaNiSe
Giacomo Mazza, Malte Rösner, Lukas Windgätter +5
TaNiSe is one of the most promising materials for hosting an excitonic insulator ground state. While a number of experimental observations have been interpreted in this way…
Localized Plasmons in Topological Insulators
Zhihao Jiang, Malte Rösner, Roelof E. Groenewald +1
We investigate in a fully quantum-mechanical manner how the many-body excitation spectrum of topological insulators is affected by the presence of long-range Coulomb interactions.…
Frequency-dependent substrate screening of excitons in atomically thin transition metal dichalcogenide semiconductors
A. Steinhoff, T. O. Wehling, M. Rösner
Atomically thin layers of transition metal dichalcogenides (TMDCs) exhibit exceptionally strong Coulomb interaction between charge carriers due to the two-dimensional carrier confi…
