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
The paper investigates how superconducting correlations are modified in helical domain‑wall ring networks that arise in moiré patterns of twisted bilayer honeycomb lattices, highli…
Green's Function Methods for Computing Supercurrents in Josephson Junctions
Eduardo R. Mucciolo, Jouko Nieminen, Xiao Xiao +3
Interest in Josephson junctions (JJs) has increased rapidly in recent years not only because of their use in qubits and other quantum devices but also due to the unique physics sup…
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…
