Our scheme can also be used to create spin-1 model of polar molecules. Thus we show that the ultracold gases of bialkali polar molecules provide a unique platform for studying the spinor condensates of rotating molecules.doi:10.1103/PhysRevA.92.033624Deng, Y.Yi, S.Physical Review A...

We study spin-polarized states and their stability in anti-ferromagnetic states of spinor (F=1) quasi-one-dimensional Bose-Einstein condensates. Using analytical approximations and numerical methods, we find various types of polarized states, including: patterns of the Thomas-Fermi type; structures ...
We present calculations of the fully quantum-mechanical spin evolution for a single spatial mode of an F = 1 antiferromagnetic spinor Bose-Einstein condensate in the presence of time-dependent microwave dressing. We focus on the coherent spin evolution driven by spin-exchange collisions, where two...
involving Bose-Einstein condensates[5, 6]. More specifically, the coherent superposition of amplitudes with different momenta resulting from the action of the Stern-Gerlach field after subsequent redefinition of the relevant quantization axis parallels that achieved through the action of the ...
Indeed, vortices, skyrmions, and other interesting exotic topological excitations are possible states in spinor condensates, which are the quantum gases made up of atoms with spin.These keywords were added by machine and not by the authors. This process is experimental and the keywords may be ...
We demonstrate detection of a weak alternate-current magnetic field by application of the spin echo technique to F = 2 Bose-Einstein condensates. A magnetic field sensitivity of 12 pT/Hz^1/2 is attained with the atom number of 5*10^3 at spatial resolution of 99 \mu m^2. Our observation...

The spatial structure of the spinor Bose-Einstein condensates with the spin degrees of freedom is analyzed based on the generalized Gross-Pitaevskii (GP) equation in light of the present spin-domain experiment on m=+/-1, and 0 of the hyperfine state F=1 of Na atom gases. The GP solution...
spinor condensatesWe develop theory for fluctuations in atom number and spin within finite-sized cells of a spinor Bose-Einstein condensate. This theory provides a model of measurements that can be performed in current experiments using finite resolution in situ imaging. We develop analytic results ...
