Dimensional hierarchy of topological bound states in the continuum
Shunda Yin, Zhenyu Wang, Liping Ye +5
Bound states in the continuum (BICs), with the ability of trapping and manipulating waves within the radiation continuum, have gained significant attention for their potential appl…
Valley edge states as bound states in the continuum
Shunda Yin, Liping Ye, Hailong He +5
Bound states in the continuum (BICs) are spatially localized states with energy embedded in the continuum spectrum of extended states. The combination of BICs physics and nontrivia…
Irregular Bloch Zener oscillations in two-dimensional flat-band Dirac materials
Li-Li Ye, Ying-Cheng Lai
When a static electrical field is applied to a two-dimensional (2D) Dirac material, Landau-Zener transition (LZT) and Bloch-Zener oscillations can occur. Employing alpha-T3 lattice…
