Nanoscale imaging of ferromagnetic vortex dynamics with scanning NV magnetometry
Jeffrey Rable, Jyotirmay Dwivedi, Nitin Samarth +3
The generation and manipulation of spin waves at the nanoscale via magnetic vortices are of considerable importance because of their broad applications across magnonic and quantum…
Helical Domain-Wall-Ring Networks Reshape Superconducting Correlations
Yi-Chun Hung, Arun Bansil
Extended domain-wall networks that emerge in moiré materials provide a distinct platform for quasi-one-dimensional electronic states. However, the interaction-driven orders in conf…
Quantum Geometry Driven Finite-Momentum Exciton Fluctuations in Flat-Band Systems
Yi-Chun Hung, Xiaoting Zhou, Arun Bansil
Quantum geometry is instrumental in stabilizing exotic phenomena in systems ranging from topological insulators to superconductors. In dispersionless flat bands, where the kinetic…
Inter-Dirac-Cone Coherence Beyond the Valley Framework
Yi-Chun Hung, Arun Bansil
Although interactions are known to generate exotic phases in pseudospin-1/2 flat-band Dirac materials, it remains an open question whether higher-pseudospin Dirac cones continue to…
Nodal Topological Superconductivity Driven by Crystalline Antiunitary Symmetry in Altermagnets
Xiao Xiao, Arun Bansil
Topological superconductivity hosts protected quasiparticles and is central to topological quantum computation, yet its realization in intrinsic materials remains challenging and o…
Emergent Quantum-Geometric Equivalence of Injection and Shift Currents
Mohammad Yahyavi, Tay-Rong Chang, Md Shafayat Hossain +3
Injection and shift currents are generally regarded as distinct nonlinear optical responses with separate microscopic origins. Here, we uncover a general hidden connection between…
Engineering Nonlinear Optical Responses via Inversion Symmetry Breaking in Bilayer Bi2Se3
Vineet Kumar Sharma, Alana Okullo, Barun Ghosh +2
Paucity of naturally occurring noncentrosymmetric materials is stimulating growing interest in engineered two-dimensional systems for nonlinear optical applications. Here, we show…
Conductivity scaling of the anomalous Hall effect in the altermagnetic semiconductor α-MnTe
Sara Bey, Shelby S. Fields, Nicholas G. Combs +22
α-MnTe is a prototypical altermagnet exhibiting a strong anomalous Hall effect (AHE), despite having a nearly vanishing magnetization. Lately, sample-to-sample variations of the am…
