We experimentally investigate the dynamics of spin solitary waves (magnetic solitons) in a harmonically trapped, binary superfluid mixture. We measure the in situ density of each pseudospin component and their relative local phase via an interferometric technique we developed and as such, fully characterize the magnetic solitons while they undergo oscillatory motion in the trap. Magnetic solitons exhibit nondispersive, dissipationless longtime dynamics. By imprinting multiple magnetic solitons…

Core structure of static ferrodark solitons in a spin-1 Bose-Einstein condensate
We develop an analytical description of static ferrodark solitons in the easy-plane phase of ferromagnetic spin-1 Bose-Einstein condensates. We find that the type-I ferrodark soliton has a single

Interaction Control and Bright Solitons in Coherently Coupled Bose-Einstein Condensates
We demonstrate fast control of the interatomic interactions in a Bose-Einstein condensate by coherently coupling two atomic states with intra- and inter-state scattering lengths of opposite signs. We

We investigate the early-time dynamics of a quasi-two-dimensional spin-1 antiferromagnetic Bose-Einstein condensate after a sudden quench from the easy-plane to the easy-axis polar phase. The
Magnetic Solitons in a Spin-1 Bose-Einstein Condensate.
Here, using a "magnetic shadowing" technique, a new type of soliton in a spinor Bose-Einstein condensate is observed, one that exists only when the underlying interactions are antiferromagnetic and which is deeply embedded within a full spin-1 quantum system.

It is found that, above a critical twist, three-dimensional wave packets are unambiguously stabilized, with no minimum energy threshold, and are predicted to feature an unprecedented experimental robustness.
Spontaneous formation and relaxation of spin domains in antiferromagnetic spin-1 condensates
It is demonstrated that spin domains form spontaneously, that is purely because of the antiferromagnetic interactions between the atoms and in the absence of external magnetic forces, after a phase separation transition.
