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…
