Unconventional Topological Weyl Dipole Phonon
Advanced Science, EarlyView.A new higher‐order topological phonon state is proposed, which integrates an unconventional Weyl dipole phonon (a charge‐3 Weyl point and three charge‐1 Weyl points) with higher‐order topology. Moreover, the two Weyl dipoles in Y(OH)3 exhibit the sextuple‐helicoid surface and hinge boundary states from the nonzero topological charge (±6) and the ...

Antibrackets, Supersymmetric $\sigma$-Model and Localization
, 1996 We consider supersymmetrization of Hamiltonian dynamics via antibrackets for systems whose Hamiltonian generates an isometry of the phase space. We find that the models are closely related to the supersymmetric non-linear $\sigma$-model. We interpret the

Hamiltonian path, routing, broadcasting algorithms for connected square network graphs
Engineering Science and Technology, an International Journal, 2023 Connected Square Network Graphs (CSNG) in the study of Selcuk (2022) and Selcuk and Tankul (2022) is reconsidered in this paper. Although (CSNG) is a 2-dimensional mesh structure, the most important feature of this graph is that it is a hypercube variant.

Topological Singularities and Edge‐State Coupling Enable Robust on‐Chip Slow Light
Advanced Science, EarlyView.This work demonstrates the first experimental observation of a topological quantum‐interference‐like effect in a 1D on‐chip system, utilizing two topological mechanisms for robust slow light. Topological charges ensure immunity to parameter deviations, while edge states provide robustness against disturbances.
