Topological classification through knotted graphs: Fermi surface dispersions and Lifshitz transitions
Hakan Akgün, Xianquan Yan, Ching Hua Lee
Knot theory has provided a rich topological taxonomy for band structures, but its reach is fundamentally limited: knot invariants classify only 1D nodal lines at gap closure, and c…
Practical Error Suppression and Mitigation for Reliable Quantum Computing
Han-Ze Li, Mengjie Yang, Xianquan Yan +3
Quantum computing is entering a transitional regime between noisy intermediate-scale quantum (NISQ) processing and early fault-tolerant quantum computation (FTQC), in which increas…
HSG-12M: A Large-Scale Benchmark of Spatial Multigraphs from the Energy Spectra of Non-Hermitian Crystals
Xianquan Yan, Hakan Akgün, Kenji Kawaguchi +2
AI is transforming scientific research by revealing new ways to understand complex physical systems, but its impact remains constrained by the lack of large, high-quality domain-sp…
Deterministic scale-invariant dynamics in a logistic Game-of-Life model
Hakan Akgun, Xianquan Yan, Tamer Taskiran +3
Scale invariance is a hallmark of criticality in complex dynamical systems. While random external inputs or tunable stochastic interactions are typically required to produce critic…
