Universal quantum corrections of two-body correlation in a weakly interspecies interacting binary Bose mixture
Rui-Yan Chen, Zhaoxin Liang, Gao Xianlong
We investigate universal quantum corrections to two-body correlations in a zero-temperature binary Bose mixture using the Cornwall-Jackiw-Tomboulis two-particle-irreducible effecti…
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…
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…
Multi-Stability in Cavity QED with Spin-Orbit Coupled Bose-Einstein Condensate
Kashif Ammar Yasir, Gao Xianlong
We investigate the occurrence of steady-state multi-stability in a cavity system containing spin-orbit coupled Bose-Einstein condensate and driven by a strong pump laser. The appli…
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…
