Efficiently gate-tunable ferromagnetism in ferromagnetic semiconductor-Dirac semimetal p-n heterojunctions
Emma Steinebronn, Saurav Islam, Abhinava Chatterjee +15
We use molecular beam epitaxy to develop a gate tunable p-n heterojunction that interfaces a canonical Dirac semimetal, CdAs, and a ferromagnetic semiconductor, InM…
Hybridization of topologically distinct quartet modes in three-terminal graphene Josephson junctions
Asmaul Smitha Rashid, Le Yi, Takashi Taniguchi +4
Multiterminal Josephson junctions offer a powerful playground for exploring exotic superconducting and topological phenomena beyond the reach of conventional two-terminal devices.…
Non-Hermitian Dynamics in Quantum Anomalous Hall Insulators
Le Yi, Emma Steinebronn, Asmaul Smitha Rashid +4
Magnetically doped topological insulators (TIs) exhibit two distinct phases: the quantum anomalous Hall (QAH) phase when the Fermi level resides within the surface gap, and a metal…
Quantum confinement effect in Sb thin films
Anuradha Wijesinghe, Yongxi Ou, Anjali Rathore +7
Antimony (Sb), an element with strong spin-orbit coupling, is predicted to undergo a topological phase transition from a topological semimetal to a topological insulator as its dim…
Visualizing the breakdown of the quantum anomalous Hall effect
George M. Ferguson, Run Xiao, Anthony R. Richardella +3
The creation of topologically non-trivial matter across electronic, mechanical, cold-atom, and photonic platforms is advancing rapidly, yet understanding the breakdown of topologic…
Imaging signatures of edge currents in a magnetic topological insulator
G. M. Ferguson, Run Xiao, Anthony R. Richardella +3
Magnetic topological insulators (MTIs) host topologically protected edge states, but the role that these edge states play in electronic transport remains unclear. Using scanning su…
Nonequilibrium Andreev resonances in ballistic graphene Andreev interferometers
Asmaul Smitha Rashid, Le Yi, Takashi Taniguchi +4
We study nonequilibrium Andreev resonances in a voltage-biased graphene three-terminal Josephson junction (JJ). We observe periodic oscillations of resistance with maxima at multip…
