Generating Giant Vortex in a Fermi Superfluid via Spin-Orbital-Angular-Momentum Coupling

Ke-Ji Chen, Fan Wu, Shi-Guo Peng +2

Spin-orbital-angular-momentum (SOAM) coupling has been realized in recent experiments of Bose-Einstein condensates [Chen et al., Phys. Rev. Lett. 121, 113204 (2018) and Zhang et al…

Ground-state phase diagram and excitation spectrum of a Bose-Einstein condensate with spin-orbital-angular-momentum coupling

Ke-Ji Chen, Fan Wu, Jianshen Hu +1

We investigate the ground-state phase diagram and excitation spectrum of an interacting spinor Bose-Einstein condensate with spin-orbital-angular-momentum (SOAM) coupling realized…

Helicoidal excitonic phase in an electron-hole double layer system

Ke Chen, Ryuichi Shindou

We propose helicoidal excitonic phase in a Coulomb-coupled two-dimensional electron-hole double layer (EHDL) system with relativistic spin-orbit interaction. Previously, it was dem…

Unfolding multi-particle quantum correlations hidden in decoherence

Ke-Ji Chen, Ho Kwan Lau, Hon Ming Chan +2

Quantum coherence is a fundamental characteristic to distinguish quantum systems from their classical counterparts. Though quantum coherence persists in isolated non-interacting sy…

Chiral Topological Excitons in a Chern Band Insulator

Ke Chen, Ryuichi Shindou

A family of semiconductors called as Chern band insulator are shown to host exciton bands with non-zero topological Chern integers and chiral exciton edge modes. Using a prototypic…
