Torsion-induced gauge structure in curved quantum waveguides
Xu-Yang Hou, Xianlong Gao, Hao Guo
We investigate the effective dynamics of a particle confined near a space curve. In the strict thin-layer reduction of the nondegenerate transverse ground state, torsion does not e…

Spectroscopic readout of chiral photonic topology in a single-cavity spin-orbit-coupled Bose-Einstein condensate
Kashif Ammar Yasir, Gao Xianlong
Topological photonic phases are typically identified through band reconstruction, steady-state transmission, or real-space imaging of edge modes. In this work, we present a framewo…

Engineering chaos in a four-mirror cavity-optomechanics with mechanical drives
Kashif Ammar Yasir, Gao Xianlong
We study occurrence of chaos in a four-mirror optomechanical cavity with mechanical drives externally interacting with two transversely located moving-end mirrors of the cavity. Th…
