Spontaneous emergence of angular momentum Josephson oscillations in coupled annular Bose-Einstein condensates [PDF]
, 2006 We investigate the nonlinear dynamics of two coupled annular Bose-Einstein condensates (BECs). For certain values of the coupling strength the nonrotating ground state is unstable with respect to fluctuations in the higher angular momentum modes. The two

Evidence for coupling between the Sagittarius dwarf galaxy and the Milky Way warp [PDF]
, 2003 Using recent determinations of the mass and orbit of Sagittarius, I calculate its orbital angular momentum. From the latest observational data, I also calculate the angular momentum of the Milky Way's warp.

Spin-orbital-angular-momentum-coupled quantum gases
AAPPS Bulletin, 2022 AbstractWe briefly review the recent progress of theories and experiments on spin-orbital-angular-momentum (SOAM)-coupled quantum gases. The coupling between the intrinsic degree of freedom of particles and their external orbital motions widely exists in the universe and leads to a broad variety of fundamental phenomena in both classical physics and ...

Structured 3D linear space–time light bullets by nonlocal nanophotonics
Light: Science & Applications, 2021 We propose the generation of 3D linear light bullets propagating in free space using a single passive nonlocal optical surface. The nonlocal nanophotonics can generate space–time coupling without any need for bulky pulse-shaping and spatial modulation ...

Spin–orbital angular momentum coupling in Bose–Einstein condensate and its spin dynamics
Results in Physics, 2023 We examine the use of Laguerre–Gaussian (LG) laser beams in the tripod scheme to create the coupling between spin and orbital angular momentum in a Bose–Einstein condensate (BEC) confined by a harmonic trap.

Acoustic orbital angular momentum Hall effect and realization using a metasurface
Physical Review Research, 2021 Vortex beams with a twisted wavefront possess both intrinsic and extrinsic orbital angular momenta. Their coupling (viz. orbital-orbital coupling) leads to an orbital angular momentum Hall effect previously found in light, providing applications in light
