Revealing quantum metric multipoles in magnetic topological insulator MnBi2Te4
Lars Sjöström, Prasanna Rout, Shahid Sattar +9
Nonlinear electronic transport has emerged as a powerful probe of the quantum geometry in topological quantum materials, where the band topology and broken symmetries facilitate po…
FIR transmission and resistively detected cyclotron resonances in InSb
M. E. Bal, N. DeÃmann, K. Saeedi +1
We have developed an experimental setup to simultaneously acquire magneto-transmission spectra and measure the photoconductive response. The low-temperature (=4.2 K) magneto-tra…
Absolute measurement of the exchange interaction in an InSb quantum well using Landau-level tunnelling spectroscopy
S. K. Clowes, C. P. Allford, D. Shearer +5
We studied InSb quantum well devices using Landau level tunneling spectroscopy through a three-terminal differential conductance technique. This method is similar to filled state s…
Atacamite CuCl(OH) in High Magnetic Fields: Quantum Criticality and Dimensional Reduction of a Sawtooth-Chain Compound
L. Heinze, T. Kotte, R. Rausch +13
We report an extensive high-field study of atacamite CuCl(OH), a material realization of quantum sawtooth chains with weak interchain couplings, in continuous and pulsed ma…
The Fermi surface of RuO2 measured by quantum oscillations
Zheyu Wu, Mengmeng Long, Hanyi Chen +12
The metallic oxide RuO has emerged as a promising altermagnet candidate, owing to reports of this material hosting antiferromagnetic ordering accompanied by a spin-split electr…
