Optical conductivity of multifold fermions: the case of RhSi
L. Z. Maulana, K. Manna, E. Uykur +3
We measured the reflectivity of the multifold semimetal RhSi in a frequency range from 80 to 20000 cm (10 meV - 2.5 eV) at temperatures down to 10 K. The optical conductivit…
Pronounced 2/3 magnetization plateau in a frustrated = 1 isolated spin-triangle compound: Interplay between Heisenberg and biquadratic exchange interactions
S. Chattopadhyay, B. Lenz, S. Kanungo +13
We report the synthesis and characterization of a new quantum magnet [2-[Bis(2-hydroxybenzyl)aminomethyl]pyridine]Ni(II)-trimer (BHAP-Ni3) in single-crystalline form. Our combined…
Observation and control of maximal Chern numbers in a chiral topological semimetal
Niels B. M. Schröter, Samuel Stolz, Kaustuv Manna +13
Topological semimetals feature protected nodal band degeneracies characterized by a topological invariant known as the Chern number (C). Nodal band crossings with linear dispersion…
Magnon-polaron excitations in the noncollinear antiferromagnet MnGe
A. S. Sukhanov, M. S. Pavlovskii, Ph. Bourges +4
We present the detailed inelastic neutron scattering measurements of the noncollinear antiferromagnet MnGe. Time-of-flight and triple-axis spectroscopy experiments were conduct…
Observation of Topological Photocurrents in the Chiral Weyl Semimetal RhSi
Dylan Rees, Kaustuv Manna, Baozhu Lu +6
Weyl semimetals are crystals in which electron bands cross at isolated points in momentum space. Associated with each crossing point (or Weyl node) is an integer topological invari…
Berry curvature unravelled by the Nernst effect in MnGe
Christoph Wuttke, Federico Caglieris, Steffen Sykora +8
The discovery of topological quantum materials represents a striking innovation in modern condensed matter physics with remarkable fundamental and technological implications. Their…
