Signature of an Ultrafast Photo-Induced Lifshitz Transition in the Nodal-Line Semimetal ZrSiTe
Robert J. Kirby, Lukas Muechler, Sebastian Klemenz +6
Here we report an ultrafast optical spectroscopic study of the nodal-line semimetal ZrSiTe. Our measurements reveal that, converse to other compounds of the family, the sudden inje…
Evidence for a Monolayer Excitonic Insulator
Yanyu Jia, Pengjie Wang, Cheng-Li Chiu +19
The interplay between topology and correlations can generate a variety of quantum phases, many of which remain to be explored. Recent advances have identified monolayer WTe2 as a p…
Landau Quantization and Highly Mobile Fermions in an Insulator
Pengjie Wang, Guo Yu, Yanyu Jia +9
In strongly correlated materials, quasiparticle excitations can carry fractional quantum numbers. An intriguing possibility is the formation of fractionalized, charge-neutral fermi…
Weyl-fermions, Fermi-arcs, and minority-spin carriers in ferromagnetic CoS2
Niels B. M. Schröter, Iñigo Robredo, Sebastian Klemenz +15
The pyrite compound CoS2 has been intensively studied in the past due to its itinerant ferromagnetism and potential for half-metallicity, which make it a promising material for spi…
Transient Drude Response Dominates Near-Infrared Pump-Probe Reflectivity in Nodal-Line Semimetals ZrSiS and ZrSiSe
Robert J. Kirby, Austin Ferrenti, Caroline Weinberg +6
The ultrafast optical response of two nodal-line semimetals, ZrSiS and ZrSiSe, was studied in the near-infrared using transient reflectivity. The two materials exhibit similar resp…
The role of delocalized chemical bonding in square-net-based topological semimetals
Sebastian Klemenz, Aurland K. Hay, Samuel M. L. Teicher +3
Principles that predict reactions or properties of materials define the discipline of chemistry. In this work we derive chemical rules, based on atomic distances and chemical bond…
