Low-threshold vortex lasing in three-dimensional cavities via flatband bound states in the continuum
Zi-Xin Zhou, Weimin Wang, Huijie Li +2
Bound states in the continuum (BICs) offer a robust route toward high-Q resonators and topological structured-light generation. While optically pumped BIC lasers have advanced sign…

Direct measurement of topological invariants through temporal adiabatic evolution of bulk states in the synthetic Brillouin zone
Zhao-Xian Chen, Yuan-hong Zhang, Xiao-Chen Sun +5
Mathematically, topological invariants arise from the parallel transport of eigenstates on the energy bands, which, in physics, correspond to the adiabatic dynamical evolution of t…
