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…

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…

Effects of Four-Phonon Scattering and Wave-like Phonon Tunneling Effects on Thermoelectric Properties of Mg2GeSe4 using Machine Learning
Hao-Jen You, Yi-Ting Chiang, Arun Bansil +1
We present a machine-learning interatomic potential (MLIP) framework, which substantially accelerates the prediction of lattice thermal conductivity for both particle-like and wave…
