Sound propagation in one-dimensional quantum droplets
Zizhou Yuan, Jiarui Xiao, Xiao-Long Chen
Sound propagation in quantum droplets differs from that in conventional Bose-Einstein condensates (BECs) because of their self-bound nature and the role of quantum fluctuations. We…
Two atoms in a harmonic trap with spin-orbital-angular-momentum coupling

Orbital angular momentum (OAM) of light represents a fundamental optical freedom that can be exploited to manipulate quantum state of atoms. In particular, it can be used to realiz…
