Collisional Dynamics of Half-Quantum Vortices in a Spinor Bose-Einstein Condensate
Sang Won Seo, Woo Jin Kwon, Seji Kang +1
We present an experimental study on the interaction and dynamics of half-quantum vortices (HQVs) in an antiferromagnetic spinor Bose-Einstein condensate. By exploiting the orbit mo…
Periodic shedding of vortex dipoles from a moving penetrable obstacle in a Bose-Einstein condensate
Woo Jin Kwon, Sang Won Seo, Yong-il Shin
We investigate vortex shedding from a moving penetrable obstacle in a highly oblate Bose-Einstein condensate. The penetrable obstacle is formed by a repulsive Gaussian laser beam t…
Half-Quantum Vortices in an Antiferromagnetic Spinor Bose-Einstein Condensate
Sang Won Seo, Seji Kang, Woo Jin Kwon +1
We report on the observation of half-quantum vortices (HQVs) in the easy-plane polar phase of an antiferromagnetic spinor Bose-Einstein condensate. Using in situ magnetization-sens…
Critical Velocity for Vortex Shedding in a Bose-Einstein Condensate
Woo Jin Kwon, Geol Moon, Sang Won Seo +1
We present measurements of the critical velocity for vortex shedding in a highly oblate Bose-Einstein condensate with a moving repulsive Gaussian laser beam. As a function of the b…
