Spectral analysis of the magneto-optical response in valley polarized PbSnSe
Xiaoqi Ding, Jiashu Wang, Mykhaylo Ozerov +7
Since the last century, considerable efforts have been devoted to the study of valley-degenerate narrow gap semiconductors, such as the PbSnSe alloy. This material poss…
Probing Berry curvature in magnetic topological insulators through resonant infrared magnetic circular dichroism
Seul-Ki Bac, Florian le Mardelé, Jiashu Wang +16
Probing the quantum geometry and topology in condensed matter systems has relied heavily on static electronic transport experiments in magnetic fields. Yet, contact-free optical me…
Energy gap of topological surface states in proximity to a magnetic insulator
Jiashu Wang, Tianyi Wang, Mykhaylo Ozerov +14
Topological surface-states can acquire an energy gap when time-reversal symmetry is broken by interfacing with a magnetic insulator. This gap has yet to be measured. Such topologic…
Fermi level tuning and band alignment in Mn doped InAs/GaSb
Logan Riney, Joaquin Bermejo-Ortiz, Gauthier Krizman +10
InAs/GaSb hosts a broken gap band alignment that has been shown to generate helical topological edge states. Upon the introduction of Mn into the structure, it has been predicted t…
Topological response of the anomalous Hall effect in MnBi2Te4 due to magnetic canting
S. -K. Bac, K. Koller, F. Lux +15
Three-dimensional (3D) compensated MnBi2Te4 is antiferromagnetic, but undergoes a spin-flop transition at intermediate fields, resulting in a canted phase before saturation. In thi…
Weak antilocalization beyond the fully diffusive regime in Pb1-xSnxSe topological quantum wells
Jiashu Wang, X. Liu, C. Bunker +9
We report the measurements and analysis of weak antilocalization (WAL) in Pb1-xSnxSe topological quantum wells in a new regime where the elastic scattering length is larger than th…
