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…
Half-quantized anomalous Hall conductance in topological insulator/ferromagnet van der Waals heterostructures
Shahid Sattar, Roman Stepanov, Alexander Tyner +3
The half-quantized anomalous Hall conductance (AHC) in topological materials is a condensed matter physics realization of the parity anomaly of (2+1) quantum field theory and an im…
Topological Magneto-Optical Switching in Even-Layered MnBiTe
Shahid Sattar, Roman Stepanov, C. M. Canali
MnBiTe (MBT) thin films provide a unique material platform in which magnetism, topology, and magneto-optical (MO) response can be tuned through layer-thickness and relative…
Magneto-optical Response of 5-SL MnBiTe in Spin-Flip States
Shahid Sattar, Roman Stepanov, A. H. MacDonald +1
Magneto-optical effects like Kerr and Faraday rotations provide a direct probe of topological order in thin films of the magnetic topological insulator MnBiTe (MBT). Motiva…
Surface Reconstructions in Thin-Films of Magnetic Topological Insulator MnBiTe
Shahid Sattar, Daniel Hedman, C. M. Canali
Understanding the nature of surface states and their exchange gaps in magnetic topological insulator MnBiTe (MBT) thin films is crucial for achieving robust topological Che…
