Dynamics of Polar-Core Spin Vortices in Inhomogeneous Spin-1 Bose-Einstein Condensates
Zachary L. Stevens-Hough, Matthew J. Davis, Lewis A. Williamson
In the easy-plane phase, a ferromagnetic spin-1 Bose-Einstein condensate is magnetized in a plane transverse to the applied Zeeman field. This phase supports polar-core spin vortic…

Many-body enhancement in a spin-chain quantum heat engine
L. A. Williamson, Matthew J. Davis
We show that ferromagnetic interactions can enhance the adiabatic performance of a quantum spin chain engine at low temperatures. The enhancement in work output is particular prono…
