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…
Extending Topological Bound on Quantum Weight Beyond Symmetry-Protected Topological Phases
Yi-Chun Hung, Yugo Onishi, Hsin Lin +2
The quantum metric encodes the geometric structure of Bloch wave functions and governs a wide range of physical responses. Its Brillouin-zone integral, the quantum weight, appears…
Quantum Geometry of Moiré Flat Bands Beyond the Valley Paradigm
Xiaoting Zhou, Yi-Chun Hung, Arun Bansil
Flat bands in moiré superlattices provide a fertile ground for correlated and topological phases, governed by their quantum geometric properties. While the valley-based paradigm ca…
Breakdown of Topological Inheritance and Twist-Induced Quantum Geometry Reconfiguration in Moiré Flat Bands
Yi-Chun Hung, Xiaoting Zhou, Arun Bansil
Since the inception of moiré quantum matter, a foundational tenet of the field has been that the quantum geometry of emergent flat bands is faithfully inherited from the low-energy…
Nested Feature Spectrum Topology: Tripartite Topological Equivalence of Feature, Entanglement, and Wilson Loop Spectrum
Yi-Chun Hung, T. Tzen Ong, Hsin Lin
Topological phases of matter are traditionally characterized through symmetry-based classifications. In cases of symmetry breaking, the projected spectrum - obtained by projecting…
