Torsion-induced gauge structure in curved quantum waveguides
Xu-Yang Hou, Xianlong Gao, Hao Guo
We investigate the quantum dynamics of a particle confined to a space curve within the thin-layer quantization framework. For a nondegenerate scalar transverse mode, torsion does n…

Lyapunov Exponents as Duality-Invariant Signatures of Critical States
Tong Liu, Gao Xianlong
Critical eigenstates are usually identified through wave-function geometry in a chosen basis, such as participation ratios, multifractal spectra, or finite-size scaling. Here we fo…

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…
